| Abstract: | Water-saving and drought-resistance rice (WDR) is a new type of rice with not only high yields and good quality, but also water-saving and drought-resistance characteristics. When this crop is irrigated, its grain yields and quality are equivalent to those of paddy rice, but its water requirement is only half that of paddy rice. It retains good yields in uplands because of its drought resistance. Furthermore, the sowing and cultivation of this rice requires lower inputs and less energy, and thus, it is very... |
