Drought is the most important abiotic stress that inhibits plant growth and reduces productivity. Varieties developed through the conventional plant breeding approach have not been adopted by the farmers of rainfed uplands because they not only lack in drought resistance but also in many of the farmer preferred traits such as high fodder yield and cooking qualities. Farmers of rainfed uplands thus cultivate old and unimproved cultivars and obtain low yields. Of the 141 varieties released for the uplands in India, only a few have become popular with farmers. In Jharkhand, most of farmers either grow the Brown Gora landrace, or its derivative, Birsa Gora 102, that have low yield and poor grain quality.
