Abstract: Since the great increases of grain yield brought by the dwarf rice and hybrid rice breeding which benefited from using sd1 gene and heterosis, rice high yield breeding seldom showed significant progress in the next successive two decades. The authors considered that, utilizing heterosis between indi
