Description :
Rice is the most important cereal as it contains protein 6.9%, fat 0.4%, carbohydrate 79.2%, mineral matter and other elements also. Realizing that, nearly half of the world’s population depends on rice for their daily diet. In the hands of plant breeder’s, pollen is the most powerful instrument in establishing new cultivators and improving existing ones. Pollen is not only a part of sexual reproduction process in the plant but a separate, metabolically active organism with half of the genetic compliment of the parent plant. The establishment of “pollen Bank” for the supply of viable pollen for mass scale hybridization in some advanced countries, is a striking example of the usefulness of pollen. In the present experiment some varieties of Oryza sativa L which are very useful in Eastern Vidarbha Zone, comprises of Chandrapur, Gadchiroli, Bhandara, Gondia and some part of Nagpur district were tested for pollen viability using TTC redox dye. Pollen material was collected at peak flowering period and subjected to following test of viability.
