摘要
以湖南、四川、广西、浙江等省具有广泛代表性的组合进行米质状况分析表明,当前三系杂交水稻的米质问题主要表现在整精米率低、垩白粒率高、垩白度大和胶稠度低。在杂交稻育种中,我们根据多年实践总结,提出了降低杂交稻垩白,提高胶稠度的新理论、新方法,并提出了具体的育种思路,以提高杂交稻整体品质水平。
Using typical combination of Hunan2, Sichuan4, Guangxi and Zhejiang to analyze rice quality, we have revealed that problems of current Three Series Quality Hybrid lies in low percentage of complete delicate rice, high percentage of white grains, and low rate of stickiness. Based on years of practice, we put forward new theory and method in rice breeding in the hope of improving the overall quality of hybrid rice.
