Development of High Yielding Cultivation Researches in Indica Super Hybrid Rice

This paper summarized the research results of high yielding physiology,ecological adaptation and cultivation technology in indica super hybrid rice(ISHR).At the present,over 12 t·hm-2 of ISHR has been recorded in different ecological regions of Southern China.And ISHR displayed vigorous root system,strong tillering capacity,proper panicle number and big panicles,coordinated ratio of source to sink,fertilizer tolerant and lodging resistant as well as the growth vigor at early stage and senescence free at late stage.The research results showed that high dry matter production as well as high economic coefficient is only one path to increase yield of ISHR.This paper also pointed out that to study the yield stability,yield formation mechanism,optimum regions grown,canopy index diagnosed as well as the key techniques of the coordinated relation between high yielding and good quality further have the important scientific meaning and application value to set up the cultivation theory and technology system.
