Studies on the Problem of Loss of Viability Rice Seeds in Storage

Abstract

Oryza sativa, the species to which most of the cultivated rices belong, has great diversity of forms in India, varying with the seasonal and climatic conditions. Nevertheless, it is usual to find a particular variety adapting itself to different conditions of soil and climate. On this capacity of varietal adaptation, depends the success of "Introduction" as a method of crop improvement. In addition to the climatic factors that might facilitate the growth and development of an introduced variety, there are others that contribute directly or indirectly to its sustained popularity. Resistance to pests and diseases, consistency in response to intensive methods of cultivation, among others, have also to be taken into account in judging of a variety as suited to permanent cultivation in a locality. Still, the conditions may not be quite favourable to every phase of the life cycle from seed to seed of the variety introduced. A particular season or seasonal conditions might favour its growth and development to maturity but subsequent weather conditions and methods of storage might affect its rest phase as seed.
