The present research problem was carried out to assess the variability parameters, heritability,
genetic advance and correlations among various quantitative traits in maize inbred lines. A total of
69 inbred lines were evaluated in alpha lattice design with 2 replications at Winter Nursery Centre,
Hyderabad. ANOVA results displays genotypes were significantly different from each other. From
the results it was depicted that Phenotypic Coefficient of Variation (PCV) was higher than
Genotypic Coefficient of Variation (GCV) indicating the influence of environment. The traits, No. of
kernels per row, Cob weight, Grain yield per cob showed high GCV and PCV values likewise Daysto 50% tasseling, Days to 50% silking and Days to 75% dry husk showed low GCV and PCV
values. Most of the characters showed high heritability and traits such as Plant height, Tassel
length, Ear length, No. of kernels per row, Cob weight and Grain yield per cob showed high GAM
and its values ranged from 21.5% to 101.30%. So, the traits such as No. of kernels per row, Cob
weight and Grain yield per cob can be used for further crop improvement in the breeding
programme. Of all the traits under study except, Days to 50% tasseling, Days to 50% silking and
Days to 75% dry husk showed positive significant correlation with grain yield per cob indicating
selection for the traits will enhance the grain yield whereas the excepted traits showed negative
significant association with grain yield per cob indicating selection for these traits is also essential
as it reduces duration of crop.
