Genetic Divergence In Baby Corn (Zea Mays L.)

Abstract

A field experiment was conducted with 80 genotypes in three replications in randomized block design at College Farm, College of Agriculture, ANGRAU, Rajendranagar during Kharif 2011-2012. The data on baby corn yield and other traits were results indicated that the varieties were distributed in eight clusters of which cluster VI had maximum intra- cluster distance (3.09) followed by cluster III (3.01) cluster I (2.99) and cluster V (2.85) and remaining clusters are having minimum cluster distances with the zero. The inter- cluster distance ranged from 2.32 (clusters V and IV) to 9.32 (clusters VII and VI). Among the clusters variations were planted height, ear height, baby corn length, cob weight, number of cobs per plant, cob yield per plant, cob yield and green fodder yield. The contribution of each character towards total genetic diversity. In that out of 13 characters plant height (42.31%), ear height (16.84%), baby corn length (17.22%) and cob yield (7.97) contributed high for divergence.
