Abstract

The challenge of weather and soil variation in block method of planting male and female parents differ, often resulting in delay of flowering up to 3 to 5 days affecting pollination. Four pollen storage periods (3, 4, 5 and 6 days) was compared for seed setting and filling in female parent. The study revealed the potential of stored pollen at 4°C up to 5 days with about 80% seed setting in DRSH-1 hybrid.
