| Abstract: | By the method of artificial hybridization and directional selection,the genes controlling the character of medium amylose content were transferred to both the female parent and male parent and the parents of hybrid rice varieties with similar amylose content were bred,then rice hybrid combinations were made by these parents.The amylose content of the grains born by these hybrid rice combinations was similar to that of their parents and there was little difference of amylose content between the grains.So it solved the problem of the great separation of amylose content between the grains born by hybrid rice varieties. |
