Abstract:
The present investigation was carried out to estimate genetic variability among thirty genotypes of onion for different characters comprised of bulb yield and its contributing characters. These genotypes were planted in Randomized Block Design with three replications during Rabi-2016-17, SKN College of Agriculture, Jobner. On the basis of mean performance, the genotype ROG-29 was the highest yielder. These genotypes may further be utilized in breeding programme aimed at improving bulb yield in onion. Analysis of variance indicated presence of considerable variability for all the characters. High GCV and PCV were observed for neck thickness, dry matter content and number of fleshy scale leaves. High estimates of heritability along with high genetic advance as per cent of mean was observed for dry matter content, pungency, TSS, bulb volume, equatorial diameter, average bulb weight and bulb yield ha¹. Therefore, these characters can laid in selection programme.
