| 摘 要： | 按照国家优质稻谷标准GB/T17891-1999,对安徽省 10 1个中籼、中粳和晚粳新组合 (品种 )进行主成分分析 ,对累计贡献率达 89.114 %的 6个主成分因子 ,即整精米率、垩白米率、垩白度、胶稠度、糙米率和直链淀粉含量等 6项指标进行达标分析。结果表明 :糙米率全部达二级标准以上 ,胶稠度达标率为 89.1% ,整精米率和直链淀粉含量达标率分别为 64 .4%和 71.3 % ,垩白米率和垩白度达标率仅为 3 2 .7%和 3 3 .7%。而且粳稻达标率高于籼稻 ,常规稻达标率高于杂交稻。提出今后杂交稻优质育种的主攻方向是降低垩白米率和垩白度 ,重视整精米率的改良。 |

| Abstract: | Six grain quality characters of 101 hybrid rice combinations (varieties) newly developed in Anhui Province were tested according to the national standard of quality rice GB/T17891-1999 and the principlal component analysis. In the principlal component of rice grain quality, first principlal component was head rice rate (HR), second was chalky rice rate (CR), third to sixth was chalkiness(C), gel consistency (GC), brown rice rate (BR) and amylose content (AC), respectively. The up-to-standard percentage was BR>GC>AC>HR>C>CR, which was 100%, 89.1%, 71.3%, 64.4%, 33.7% and 32.7%, respectively. To lower CR and C and to improve HR were considered to be the main targets of quality breeding of hybrid rice, in the future. |
