Abstract

Rice is one of the most important staple foods for huge population of more than 1000 million in India which ranks first in hectare (42.1 million ha.) and is second only to China in production (85 million tons) among the countries of the world. The most spectacular success of hybrid rice technology in China in 1976 showed that exploitation of hybrid vigour is one of the feasible options to overcome the yield barrier. The other option for stepping up the potential yield is to modify plant type. In fact, China increased the area under hybrid rice from 0.14 million ha in 1976 to 18.1 million ha in 1992 out of the total area of 33.6 million ha producing 187.1 million tons of rice, accounting for 54% rice area and 63.9% of the production through hybrid rice. It encouraged the Indian Council of Agricultural Research(ICAR) to exploit this hybrid rice technology during VIII plan period by sanctioning a project on “Promotion of Research and Development Efforts on Rice Hybrids” to step up potential rice yields. Finally our study indicates towards yield potentiality of the hybrid DRRH1as compared to popular inbred check. This phenomenon perhaps concludes a narrow range of adaptability of the hybrid to abiotic stresses which needs elaborate study.
