Introduction of Rice Germplasm-A Boon for India

摘要

India is supposed to be a part of the homeland for cultivated rice. Tremendous amount of variability existed in the landraces of rice germplasm, which has been estimated to be more than 15,000 accessions. However, in the process of evolution and natural selection some of the characters were favored and some other characters got eliminated. Thus there was and has been a necessity of introducing rice cultivars from other geographical regions for the purpose of increasing the yield.
