to search the male sterile line from segregating population
The experiment was conducted at Spices Research Centre, Shibganj, Bogra during rabi season (2012 -2013) for searching the male sterile line from segregating population. The planting materials were Hybrid Onion-1, 2, 3 & 4. These seeds were collected from different seed company. Bulbs of these hybrids were planted on November 2012. The unit plot size was1.0m x 1.0m having plant spacing of 25cm x 20cm. Onion was fertilized with recommended dose of cow dung 10 t/ha, N115, P54, K75, S20, Zn3 and B2 Kg/ha Weeding was done at 25, 50, 75 & 100 days after planting. Irrigation was applied at 20, 40, 60, 80 & 100 days after planting. Fungicide (Ruvral @ 2.5 g/l) was sprayed at 15 days interval starting from 60 day after planting. Insecticide (Admare @ 0.5 ml/l) was sprayed at 15 days interval starting from 90 day after planting.
