Nine advanced selected synthetic populations and a check variety of sweet corn
were used to compare the performance among populations, to determine correlations
between important traits in the populations, and to estimate a broad-sense heritability
of the traits. The populations showed a wide range of performance in fresh ear
yield and other traits and yield components measured. The potential of two populations,
MMX368NS and P368 was revealed, and could be short-listed for further testing
and selection before release as new varieties. Population MMX368NS, in particular
possessed high ear yield of 8750 kg/ha, high number of ears per hectare, moderate
plant height, moderate maturity, superior ear measurements as yield components
and moderate brix content. Number of ears per hectare, ear weight, ear length
and number of kernels per ear row were found to be most correlated with ear
yield, while plant height, days to tasseling and ear length were the traits
found to be most heritable in these populations of sweet corn. This information
would be greatly useful to help breeders in making appropriate selection in
genetic improvement of tropical sweet corn populations.
