Abstract:

Identification of ideal genotype is the utmost important to trigger desirable qualitative and quantitative characters. The present investigation was meant to assess the degree of variability, heritability, genetic advance and genetic divergence in kharif onion (Allium cepa L.) cultivars using eleven quantitative and six biochemical traits. Out of twenty-two cultivars Agrifound Dark Red had maximum yield whereas minimum recorded in Arka Bindu. The analysis of variance was highly significant for all the characters studied. Phenotypic coefficient of variance (PCV) was higher than genotypic coefficient of variance (GCV) for all the traits but the difference was less in average bulb weight, TSS, total sugar, ascorbic acid, pyruvic acid and phenol. Such difference indicates higher contribution of genotypic effect towards phenotypic expression. High heritability along with high genetic advance as percent of mean was recorded in neck thickness, average bulb weight, total sugar, ascorbic acid, phenol and pyruvic acid which refers the presence of additive gene action for the expression of these traits. This study would ease the selection of potential genotypes for yield related traits and help breeders in selection of promising diverse parents for purposeful breeding programmes.
