  The effects of NaCl stress on in vitro induced potato plantlets of variety of potato Solanum tuberosm L.) commercial variety cardinal was studied at Potato Research Center, Abbottabad, NWFP, Pakistan. Five NaCl treatments, each consisting of 0, 1, 2, 3 and 4% were used. Viability percentage, fresh weight of plantlet and height of plantlet was decreased by given range levels of NaCl. The effect of all treatments was very drastic on length of roots and number of roots per plantlet where no response was recorded. The treatment of 4% NaCl depressed all the parameters understudy. The results indicate that the variety "Cardinal" is not salt tolerant, even at 1% salt concentration.

  To estimate mid-parent and better-parent heterosis in Brassica napus L. an experiment was conducted at NWFP Agricultural University, Peshawar, during 2004-05 and 2005-06 using 8x8 full diallel crosses. All the 56 F1 hybrids and their parents were planted in a randomized complete block design with three replications. Out of 56 hybrids, negative mid-parent and better-parent heterosis were estimated in 28 and 25 hybrids for 50% emergence, in 30 and 17 hybrids for 50% flowering, in 34 and 49 hybrids for physiological maturity and in 27 and 38 hybrids for plant height, respectively whereas positive heterosis were estimated in 28 and 23 crosses for primary/branches plant. However, significant negative mid-parent and better-parent heterosis were recorded in 6 and 7 hybrids for 50% emergence, in 17 and 04 for 50% flowering, in 11 and 20 for physiological maturity, in 27 and 36 for plant height while significantly positive heterosis was recorded in 27 and 23 crosses for primary branches/plant, respectively. Better-parent heterosis reduced to 25% for emergence, 2.78% for flowering, 4.08% for maturity and 21.22% for plant height whereas it reached to 50% for branches/plant. Among parents, NUR1, NUR2, NUR4, NUR5 and NUR9 were found superior when used in different cross combinations. Hybrids NUR3xNUR4, NUR5xNUR1 and NUR5xNUR7 could be used to develop early maturing while NUR3xNUR2 and NUR5xNUR8 would be helpful to develop medium sized with robust structured brassica lines that could be tolerant to lodging with greater yields.

  Combining ability analysis of eight Brassica napus L. genotypes was estimated using diallel crosses. Analysis of variance for genotypes revealed highly significant differences (p=<0.01) for all traits. Components of combining ability analysis exhibited that, GCA was highly significant (p=<0.01) for 50% flowering, number of primary branches/plant and number of pods main/raceme, while non-significant for maturity and plant height whereas SCA and RCA effects were highly significant for all traits. GCA effects were higher than SCA and RCA for majority of the traits indicating that additive gene effects controlled the expression of these traits. RCA effects were greater than GCA and SCA for maturity showing that reciprocal crosses have higher potential than direct crosses for this trait. The parent genotypes NUR1, NUR2, NUR4, NUR7 and NUR8 and hybrids NUR1 x NUR3, NUR2 x NUR3, NUR2 x NUR4, NUR2 x NUR8, NUR4 x NUR2, NUR7 x NUR1, NUR8 x NUR2, NUR8 x NUR3 and NUR9 x NUR4 had higher GCA and SCA effects, respectively therefore could be used to develop early maturing, medium height and high yielding lines.

  The effect of three different auxins viz, naphthalene acetic acid (NAA), indole acetic acid (IAA) and indole butyric acid (IBA) each at four levels (0, 0.1, 0.5 and 1.0 mg l-1) was evaluated on meristem culture of Potato (Solanum tuberosum L.) for production of virus-free plantlets. Maximum plantlet height (8.3 cm), largest number of nodes/plantlet (7.3) and highest number of leaves/plantlet (8.9) were recorded at 0.5 mg l-1 of NAA followed by IBA at 1 mg l-1, whereas extensive number of roots/plantlet (23.7) as well as the earliest microtuber formation (17 days, after transplantation) were recorded at 1 mg l-1 of IBA followed by NAA at 0.1 mg l-1. Largest root (4.2 cm) was observed for IAA at 1 mg l-1 concentration. Enzyme Linked Immunosorbent Assay (ELISA) test proved that all plants were free of Potato Virus X (PVX), Potato Virus Y (PVY) and Potato Leaf Role Virus (PLRV), except one which was positive for Potato Virus X (PVX) virus.

  Physiological response of six wheat genotypes to Water defibit conditions was studied. Leaf water potential (LWP) and relative leaf water content (RLWC) were used to asses the influence of water stress at four leaf, heading, anthesis and senescence stages. Different stages of plant appeared to be negatively correlated with LWP because with growing age, LWP became more negative. The treatment effects dr, LWP at different stages of plant were significantly different, maximum value was recorded for full irrigation folloWed by gradual decrease in one-half and one-fourth irrigation. Genotypes appeared to differ significantly at anthesis only Unlike LWP, treatments as well as genotypic differences for RLWC at heading and anthesis were significani Among the genotypes, Barani-83 and Khushal-69 maintained higher LWP at anthesis, may be due to having drought avoidance potential, as their yield was comparatively less affected by external water stress. Sonalika and PR-33 appeared to tolerate lower LWP to produce reasonable yield hence can be regarded drought tolerant.

  Drought tolerance potential of five F10 brassica lines derived from interspecific crosses involving three genotypes of B. napus, two of B. juncea and one of B. carinata was assessed under green house conditions during crop season 1992-93. Relative leaf water contents (RLWC) were significantly altered by the three levels of moisture stress at flowering stage but genotypic differences were significant at the pod formation stage only. Leaf water potential (LWP) decreased with increasing stress and increased with age from flowering to pod stage. Under stress conditions plants generally took longer to complete 100% flowering, however, maturity was not significantly delayed. Brassica juncea was the earliest in reaching maturity followed by B. carinata and B. napus, respectively, while lines showed little differences. Leaf area decreased significantly with moisture stress, Whereas genotypic differences were significant for pod length, number of pods/main stock and number of secondary branches and non-significant for number of seed/pod and grain yield/plant. The Lines AY and WY derived from crosses between Altex X Yellow Raya and Westar x Yellow Raya, respectively were proved to be stress tolerant.

  Morphological differences among the Brassica lines for all the characters were statistically significant. Among the lines, AY produced maximum yield and was closely followed by WL and AAR with lower but statistically similar trend. As expected these lines were also statistically higher in number of pods per main stalk, pod size and thousand grain weight. Present efforts were quite successful in determining the genetic potential of different lines for yield and its components and are recommended for further testing and if proved stable could be released as an improved variety(s).

  An 8x8 full diallel set of bread wheat (Triticum aestivum L.) was studied for heterosis and heterobeltiosis. The magnitudes of heterosis (mid-parent) and heterobeltiosis (better-parent) from F1 were calculated for days to heading, flag leaf area, plant height, spike length, days to maturity and harvest index. All the 56 F1 hybrids and their parents were planted in a randomized complete block design in three replicates. Out of the 56 F1 hybrids, 18 and 16 hybrids for days to heading; 11 and 2 for flag leaf area; 24 and 15 for spike length; 8 and 3 for days to maturity and in 3 and 1 for harvest index expressed significant heterosis and heterobeltiosis, respectively. Maximum limits of heterobeltiosis for flag leaf area, spike length, harvest index, plant height, days to heading and days to maturity were 22.3, 13.03, 11.23, 3.27, 2.60 and 1.82%, respectively. Among parent cultivars, Takbeer, Inqilab-91, Tatara and Idaho-458 proved to be superior combiners. Populations of Tatara x Khattakwal, Takbeer x Inqilab-91, Idaho-458 x Fakhre Sarhad, Fakhre Sarhad x Takbeer and Ghaznav-98 x Takbeer were the best for most of the traits and their use in breeding programmes is suggested.

  For determination of good combiners in Brassica napus L. genotypes, a study was conducted 8x8 diallel during 2004-05 and 2005-06. F1s and parents were evaluated for combining ability for yield associated traits. Analysis of variance revealed highly significant differences (p≤0.01) for all traits. Components of combining ability analysis exhibited that, GCA was highly significant (p≤0.01) for number of seeds/plant, while significant (p≤0.05) for number of pods/plant and pod length whereas non-significant for 1000 seed weight and seed yield/plant. SCA and RCA effects were highly significant for all traits. GCA effects were higher than SCA and RCA for number of pods/plant and number of seeds/pod indicating that additive gene effects controlled the expression of these traits. The SCA effects were of greater magnitude than GCA effects for 1000 seed weight showing the contribution of non-additive gene effects. RCA effects were greater than GCA and SCA for number of pods/plant and seed yield/plant showing that reciprocal crosses have higher potential than direct crosses for these traits. The parent genotypes NUR1, NUR3, NUR4 and NUR9 and hybrids NUR1xNUR7, NUR2xNUR1, NUR2xNUR8, NUR3xNUR1, NUR3xNUR9, NUR4xNUR7, NUR5xNUR2, NUR5xNUR8, NUR7xNUR4 and NUR8xNUR1 had higher GCA and SCA effects, respectively therefore could be exploited for further selection of high yielding progenies. The overall study revealed the importance of both additive and non-additive genetic variability suggesting the use of integrated breeding strategies which can efficiently utilize the additive as well as non-additive genetic variability.

  Broad sense heritability estimates, genetic advance and Relative Expected Genetic Advance (REGA) were computed for different fodder yield related traits in two maize populations during Kharif 2002 and 2003. Two maize populations, DRS; developed through recurrent selection and DMS developed through mass selection, were grown in modified RCBD with two replications. Mean squares from the analysis of variance among S1 families for both maize populations indicated highly significant (p<=0.01) differences for all the studied traits. Estimates of genetic variances were significant for all traits except stem girth in both populations. Genetic variances in comparison to respective environmental variances were greater for majority of the traits in both populations. Heritability estimates were high and significant for all the traits in both populations. Comparison of two populations revealed that heritability estimates were higher for internode length and fresh fodder yield in the DRS population and for plant height, stem girth, flag leaf area and dry matter content in the DMS population. Genetic advance was higher for internode length, flag leaf area, fresh fodder yield in the DRS population and for plant height, stem girth and dry matter content in DMS population. REGA% was higher for internode length and fresh fodder yield in DRS population while DMS population attained higher values for plant height, stem girth, flag leaf area and dry matter content. The higher heritability estimates, genetic advance and REGA for fresh fodder yield in DRS population indicates that recurrent selection method was comparatively more effective in improving maize population for fodder yield parameters.

  Wheat production is often reduced by terminal heat stress therefore present study was aimed to characterize wheat genotypes for their heat tolerance for some important traits. Plant material was composed of sixteen wheat (Triticum aestivium L.) genotypes including two check cultivars. Wheat genotypes were sown in the field at two dates i.e., November 15 (normal sowing) and December 13 (delayed sowing) during winter seasons of 2003-2004 and 2004-2005. Combined analysis of variance (for two years) showed that mean values for years were highly significant at p=<0.01 for majority of the traits, differences were significant (p=<0.05%) for grain filling duration while non-significant for days to emergence. For seasons; differences were highly significant for all parameters, whereas for genotypes; the differences were highly significant for all parameters except grain filling duration where differences were non significant whereas, response for different interactions was variable. In present experiment, generally late sowing imposed negative effects on all traits. However, two years combined data showed that minimum difference between early and late sowing was 23 days for heading (CT-4), 7 cm for leaf area (CT-12, 13 and 14), 6.3 cm for plant height (CT-10) and 3 days for grain filling duration (CT-9) whereas, CT-10 matured 29 days earlier when sown late in comparison to the normal sowing time. From the experiment it was concluded that CT-4 and CT-10 had built in terminal heat stress escape mechanism which could be used for the development of new early maturing variety.

  To estimate heterosis over mid-parent and better-parent of F1 hybrids in Brassica napus L. an experiment was conducted during 2004-05 and 2005-06 using 8x8 full diallel crosses. All the 56 F1 hybrids and their parents were planted in a randomized complete block design with three replications. Out of 56 hybrids, positive mid-parent and better-parent heterosis were found in 44 and 32 hybrids for number of pods/raceme, in 27 and 19 hybrids for number of pods/plant, in 27 and 15 hybrids for pod length, in 26 and 20 hybrids for number of seeds/pod, in 50 and 39 crosses for 1000-seed weightand in 21 and 07 crosses for yield/plant. However, significant positive mid-parent and better-parent heterotic effects were recorded in 44 and 32 hybrids for pods/raceme, in 26 and 19 hybrids for pods/plant, in 11 and 09 hybrids for pod length, in 21 and 20 hybrids for seeds/pod and in 07 and 04 crosses for 1000-seed weight. Better-parent heterosis reached to 66.67% for pods/raceme, 60.85% for pods/plant, 16.03% for pod length, 27.27% for seeds/pod, 54.62% for 1000-seed weight and 1.02% for grain yield. Among parents, NUR1, NUR4, NUR5, NUR7, NUR8 and NUR9 proved to be superior when used as parents in most of the hybrid combinations. Crosses NUR1xNUR7, NUR1x NUR9, NUR5x NUR4, NUR4xNUR9, NUR3xNUR9 and NUR8xNUR9 were best for yield associated traits and their further utilization in breeding programmes would be useful for developing high yielding genotypes.

  This study was conducted during the years 2002-2003 at the Research Farm of NWFP Agricultural University, Peshawar (Pakistan) to compare selected maize populations for fodder parameters. Two maize populations, one developed through recurrent selection (DRS) and the other through mass selection (DMS), each comprising of 125 S1 families were tested in modified Randomized Complete Block Design (RCBD) with two replications. Six fodder related traits viz., plant height, internode length, stem girth, flag leaf area, dry matter content and fresh fodder yield were determined. Mean squares from the analysis of variance among S1 families for both maize populations indicated highly significant (p<=0.01) differences for all the parameters. Data ranged from 58.7-201.9 and 60.8-184.1 cm for plant height, 6.6-16.3 to 13.0-18.5 cm for internode length, 0.7-2.0 to 0.7-1.6 cm for stem girth, 9.7-177.2 to 9.0-120.0 for flag leaf area, 124.0-680.0 to 182.0-652.0 g kg-1 for dry matter content and 600.0-6720.0 to 360.0-5040.0 kg ha-1 for fresh fodder yield in DRS and DMS population, respectively. The mean values were 124.5 and 134.5 cm for plant height, 11.9 and 12.6 cm for internode length, 1.0 and 1.1 cm for stem girth, 52.1 and 43.8 cm2 for flag leaf area, 354.2 and 392.8 g kg-1 for dry matter content and 2167.9 and 2166.2 kg ha-1 for fresh fodder yield in DRS and DMS population, respectively. Coefficient of variation was comparatively smaller (less than 10%) for plant height, internode length and stem girth in the DRS population and plant height, internode length, stem girth and dry matter content in the DMS population. The wider range among S1 families of both populations depicts the existence of sufficient variation for these traits which can, therefore be exploited in maize breeding programs aimed at improving fodder characteristics.

  Considerable variation among the lines were observed for total oil contents, oleic acid, linoleic acid, linolenic acid, erucic acid and glucosinolates. Maximum oil contents were recovered from WY and MG followed by a group of five lines with almost similar values (47%) and these could be a material of choice for transferring this potential into a desirable background. None of the lines exhibited desired level of erucic acid and glucosinolates. Present study successfully identified lines with improved oil content which could be advanced and utilized in future breeding programs for high oil content.
