Abstract:
The present investigation was undertaken with the objective to assess variability (ANOVA, PCV and GCV), heritability, genetic advance, genetic advance as percentage of mean (GAM) and grain zinc concentration in 30 biofortified inbred lines of maize (Zea mays L.) for 11 traits. Trials were conducted during kharif 2017 at Agricultural Research farm, Institute of Agricultural Sciences in Randomized Block Design with three replications. Each entry was planted in row-to-row and plant-to-plant spacing of 60 cm x 20 cm. All the recommended packages of practices were followed to raise a good crop. The data were analyzed for variation using ANOVA. Over the year high GCV and PCV was observed for 100 seed weight followed by ear height, tassel length, Zn concentration, cob diameter, plant height and grain yield per plant. High heritability was observed for all the character except for days to 50% tasseling, days to 50% silking and cob length without husk. The high heritability coupled with high genetic advance as percent of mean was recorded for 100 seed weight, tassel length, ear height, Zn concentration, grain yield, plant height and cob diameter.
