Selection of best germplasm on the basis of selection parameters (Heritability, genetic advance & correlation) in maize (Zea Mays L.)

Abstract

Estimates of heritability was found for grain yield per plant, 100 kernel weight, cob height, plant height and no. of grain rows per cob. The character grain yield per plant show moderate heritability with high genetic advance over mean. The economic trait grain yield per plant show positive significant association with the characters namely; days to 50% tasseling, days to 50% silking, days to 75% dry husk, cob height, cobs per plant, grain rows/ cob, grains per row, cob weight, 100 grain weight and grain weight per cob.
