Genetic Variability Assessment in Onion (Allium cepa L.) Genotypes


Author(s): Pushpendra Singh, AK Soni, Pratishtha Diwaker, Atma Ram Meena and Deepika Sharma

Abstract: The present investigation was carried out to estimate genetic variability among thirty genotypes of onion for fourteen characters comprised of bulb yield and its contributing characters. These genotypes were planted in Complete Randomized Block Design with three replications during Rabi-2016-17, SKN College of Agriculture, Jobner. On the basis of mean performance, the genotype RO-1 was the highest yielder followed by RO-643, RO-252, and RO-647. 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 fourteen 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 aid in selection programme.
