Abstract: An experiment was conducted at Indian Institute of Horticultural Research, Bangalore in Rabi season during the years 2001-2002 and 2002-2003 to study the flowering of CMS (A) and pollinator lines (C) of onion cv. Arka Lalima for effective synchrony in hybrid seed production. Results indicated that days to 100% flowering and days to complete flowering in a plant varied significantly in the parental lines and C line was earlier than A line by 12 days and 25 days respectively. The duration of flowering in a plant was also lesser in C line (23 days) than in A line (29 days). Due to lack of floral synchrony between parental lines, pollen availability is a limiting factor in hybrid seed production of Arka Lalima. Delayed planting of C lines by one week after planting A lines resulted in synchronised flowering of parental lines at peak flowering stage. This also resulted in higher fruit set (80%) and hybrid seed yield (15g/plant) as against planting of A and C lines simultaneously (29.54% and 0.38g respectively).
