Comprehensive Evaluation of 11 Rice Varieties(Lines)in Yanhe County
摘要
Abstract
To screen rice varieties(lines)suitable for promotion and cultivation in Yanhe County,this study analyzed the growth period,yield components,and grain quality of 10 major promoted varieties(lines),including Aofuyou287 and Qin-you808,using Yixiangyou2115 as the control(ck).The results showed that the growth periods of the 11 varieties(lines)ranged from 137 to 144 days.Except for Huazheyou210,which had a higher yield than the control,the yields of all other vari-eties(lines)were lower than that of ck.The yields ranked from high to low were for Huazheyou210,Yixiangyou2115,Jingli-angyou534,Taiyou390,Quanyousimiao,Aofuyou287,Yexiangyouyousi,Huazhongyou9367,Yexiangyou9901,Zhongzheyou8,and Taiyou808.The yield components with larger coefficients of variation among the varieties(lines)were grains per spike,filled grains per spike,and effective panicles,while plant height showed a smaller coefficient of variation.Membership func-tion analysis revealed considerable differences in quality among the varieties(lines).The chalky grain rate exhibited the larg-est coefficient of variation(52.97%),while the cooked rice score showed the smallest difference(2.73%).The comprehensive quality scores ranked from high to low were for Huazheyou210,Aofuyou287,Jingliangyou534,Quanyousimiao,Taiyou390,Yixiangyou2115,Taiyou808,Huazhongyou9367,Zhongzheyou8,Yexiangyou9901,and Yexiangyouyousi.关键词
