Abstract:
The present investigation on “Genetic variability, heritability and genetic advance in onion (Allium cepa L.) for bulb yield and its component characters” was carried out at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad, Karnataka, during the rabi season of 2021-2022. The study was undertaken to evaluate the variability present among the rabi genotypes and predict the results for hybridization programme. Thirty-seven genotypes of onion were used for the experiment. On the basis of mean performance RVC-21-40 was found best performing genotype with highest bulb yield (35.20 t/ha). Higher estimates of heritability were found for pyruvic acid followed by bulb weight, yield, TSS, polar diameter and equatorial diameter characters, indicating the presence of high variability, which suggests that these traits can aid in simple selection which could be helpful for further crop improvement.
