  Genetic studies were conducted on six marketable cultivars of wheat (Triticum aestivum L. emp. Thell) viz; Inqilab, Khyber 87, Soghat, Sarsabz, Rohtas 90 and Pak 81 and their three F1 hybrids; Khyber 87 X Inqilab, Rohtas 90 X Pak 81, and Soghat X Sarsabz in Pakistan. Data for various morphological and biochemical traits were taken and analyzed for heterosis, correlation and path co-efficient. Significant heterosis for grain yield, biomass, plant height, flag leaf area, spike length, spikelets per spike and 1000-seed weight, protein content, gluten, reducing sugars, fats and minerals was recorded in F1 for all the three crosses. Analysis of variance revealed significant sum of genetic variability for all the characters. Positive and significant correlation of grain yield was recorded with plant height, spike length and biological yield at the genotypic level. There was a positive and significant association between protein content and number of spikelets per spike and protein and gluten content at genotypic level. However, correlation between grain yield and 1000-seed weight was negative and highly significant. In general, more correlation coefficient was recorded at the genetic level as compared to phenotypic level. While improving the yield potential of wheat varieties under investigation, direct simultaneous selection based on plant height, spikelets per spike, biological yield, harvest index and protein content of kernel would be advantageous. This information will ultimately lead to the determination of suitable plant types in wheat (Triticum aestivum L. emp. Thell)

  Seventeen soybean varieties were evaluated for yield components at National Agricultural Research Centre, Islamabad during July to October 2002. Data were recorded for traits viz. leaf area, chlorophyll content, 1st pod height, days to 50% flowering, days to flowering completion, days to pod initiation, days to 50% maturity, plant height, number of pods per plant, number of branches per plant, number of unfilled pods, number of shattered pods, 100 seed weight, grain yield, oil content, protein content. Data were analyzed for analysis of variance, heritability, correlation coefficient and path analysis. Results of analysis of variance revealed that there were highly significant differences among genotypes for all the characters. High heritability was recorded in 100 grain weight, days to maturity, days to flowering completion, days to pod initiation, leaf area, days to 50% flowering, oil contents, no. of shattered pods/plants and grain yield/plant, plant height and protein contents respectively indicating the additive type of gene action. On the basis of heritability selection for these traits will provide greatest improvement in soybean. Correlation coefficient of yield was significant and positive with leaf area, pods per plant and oil contents. Therefore, increase in these traits will ultimately increase the grain yield. Path coefficient analysis revealed that days to pod initiation had maximum direct contribution to yield followed. Therefore, it is suggested that this characters can be considered as selection criteria in improving the bean yield of soybean genotypes
