GENETIC-VARIABILITY AND CORRELATION IN ONION (ALLIUM-CEPA)

A field experiment was conducted during the winter season of 1990-93 to study genetic variability and correlation in 9 cultivars ('Nasik Red','N 53','VL I ','VL 3','Multiplier', 'Bombay White','Bombay Red', 'Gujarat White' and 'Puna Red') of onion (Allium cepa L.). Bulb weight, bulb yield/ha and dry leaves/plant had high genotypic coefficient of variation (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.
