Selection indices for yield in rabi sorghum (Sorghum bicolor L. Moench) genotypes
Various selection indices were constructed for yield in rabi sorghum genotypes using 45 genotypes. Among various traits,plant height, 1000-seed weight and fodder yield had significant and positive genotypic correlation with the seed yield perplant. Among the selection indices, the expected genetic g...
