摘　　要：探讨不同小麦品种光合性能,筛选高光效小麦品种,对促进小麦高光效育种研究进程奠定重要基础。选用河南省新中国成立以来28个主推品种,通过测定小麦灌浆期旗叶的叶绿素含量、叶绿素荧光参数等,采用主成分分析法对28个小麦品种的13个光效率相关指标进行研究。结果表明,不同小麦品种间13个光效率指标变异系数为2.33%~26.53%。主成分分析提取的前3个主成分累计贡献率为88.22%,表明能全面反映光效率信息。基于光效率综合得分和小麦产量,筛选出高产高光效品种(百农307、周麦16、洛麦6号、内乡188、豫麦49、郑麦7698和百农207)、低产高光效品种(豫麦10、豫麦21、豫麦25和周麦27)、高产低光效品种(矮抗58、宝丰7228、高优503、温6、西农979、豫麦34、郑麦366、郑麦9023和周麦18)和低产低光效品种(阿勃、阿夫、辉县红、陕农7859、西安8号、豫麦54、豫麦18和豫麦13)。To explore the photosynthetic performance of different wheat varieties and screen high photosynthetic efficiency wheat varieties,and to provide an important foundation for promoting high photosynthetic efficiency of wheat breeding research process,we measured the changes of chlorophyll content and chlorophyll fluorescence parameters of 28 representative wheat cultivars in Henan Province since the founding of new China.And the principal component analysis method was used to study the 13 photosynthetic efficiency indexes of 28 wheat cultivars.Results showed that the coefficient of variation of 13 photosynthetic efficiency indexes was 2.33%-26.53%.The cumulative contribution rate of the first three principal components extracted by principal component analysis was 88.22%,which fully reflected the photosynthetic efficiency information.Combining with the comprehensive scores of high photosynthetic efficiency of each wheat variety and grain yield,the high yield photosynthetic efficiency wheat varieties were Bainong 307,Zhoumai 16,Luomai 6,Neixiang 188,Yumai 49,Zhengmai 7698 and Bainong 207;the low yield and high photosynthetic efficiency varieties were Yumai 10,Yumai 21,Yumai 25 and Zhoumai 27;the high yield and low photosynthetic efficiency varieties were Aikang 58,Baofeng 7228,Gaoyou 503,Wen 6,Xinong 979,Yumai 34,Zhengmai 366,Zhengmai 9023 and Zhou 18;and low yield,photosynthetic efficiency varieties were A Bo,A Fu,Huixianhong,Shaannong 7859,Xi’an 8,Yumai 54,Yumai 18 and Yumai 13.
