Abstract:

The experiment was conducted at Agricultural and Horticultural Research Station, Kathal agere during kharif 2018. Estimation of variability parameters like environmental variability, Genotypic variability, Genotypic coefficient of variability, Phenotypic variability, Phenotypic Coefficient of Variability, Heritability (h2), Genetic advancement at 5%, Genetic advancement as % of mean 5% and General mean. In the present study twenty seven diverse hybrids were grown in RCBD design with three replications during Kharif 2018 to study the genetic parameters viz. ANOVA, GCV, PCV, h2 and Genetic Advance (GA). The results indicates that ANOVA for all the characters viz. cob weight, shelling %, moisture %, initial plants and, final plant stand, cob count, days to 50% pollen shed, days to 50% silking, days to70% dry husk, plant height, ear height are highly significant while grain yield showed significant values. The high GCV and PCV values were observed for grain yield, cob weight while moderate GCV and PCV values were shown by moisture %, days to 70% dry husk and cob count. High heritability coupled with high expected genetic advance in percent of mean was observed for grain yield, cob count, days to 70% dry husk, plant height and ear height. Conclusively PCV was higher GCV indicates that environmental role in the expression of these traits.


Keywords: Heritability, Variability, Pollen, Silking
