Abstract:

The present investigation was carried out in 25 sweet corn inbred lines during Rabi 2019-20. Significant differences among genotypes for most of the traits were noticed, indicating the presence of substantial genetic variability. Phenotypic coefficients of variation (PCV) were higher than genotypic coefficients of variation (GCV), indicating the role of experimental variance to the total variance. Moderate to high range of GCV, PCV, heritability and genetic advance over mean were recorded for ear height, ear length, number of rows per ear, number of kernels per row, cob weight with husk and without husk and PFSR disease score, which indicates the importance of these traits in selection of sweet corn inbred lines. Ear height, ear length, number of rows per ear, number of kernels per row, cob weight without husk were very important for selection of sweet corn genotypes as they recorded positive significant correlations and direct effects were also recorded by some of these traits on cob weight with husk i.e. green cob yield.
