Oryza sativa L. (Rice) belongs to family poaceae is annual grass. The pollen grains of this plant are short lived. In the course of plant breeding, pollen serves as a powerful means in establishing genetic bases that lead to new cultivars, as also to improve the existing one. The experimental results reveal that the pollen grains of some varieties could be well presented for a period of 20 days at high relative humidity (RH) and low temperature (3oC). The germinabilit of pollen was observed to be good upto 6th day of storage and during the remaining days there appears to be slow decline in the geminiability of stored pollen grains.
