A field experiment was conducted during the winter season of 1990-93 t
o study genetic variability and correlation in 9 cultivars ('Nasik Red
','N 53','VL I ','VL 3','Multiplier', 'Bombay White','Bombay Red', 'Gu
jarat White' and 'Puna Red') of onion (Allium cepa L.). Bulb weight, b
ulb yield/ha and dry leaves/plant had high genotypic coefficient of va
riation (21.95, 20.72 and 20.28 respectively), heritability (97.88, 96
.95 and 95.92% respectively) and genetic advance (44.80, 42.05 and 40.
96% respectively). Bulb yield showed strong positive correlation with
bulb weight and neck girth.
