Studies on Genetic Variability and Heritability in Bulb Onion (Allium cepa L.) in North-Western Plains of India

A study on genetic variability, heritability and genetic advance was carried out in bulb onion for 13 traits using 43 accessions. The range of variation was highest for bolting (0 to 51.30%), followed by days to maturity (110 to 155 days) and bulb weight (44 to 87.03g). Values for phenotypic coeffic...
