杂交稻产量与主要农艺性状的灰色关联度分析
Grey relational grade analysis between grain yield and main agronomic traits of hybrid rice
摘要
Abstract
Twelve hybrid rice eultivars,including Fengliangyou 4,Yangnongyou 3611,Xiannong 303,Jinyou 987,Dongyou 1388,Fengyou 126,45s/RX10,Jingchuyou 1537,Ⅱ You 838,Xiangyou 218,Chuanxiang 29A/AW03 and SD-88,were used to analyze the relationships of grain yield(GY)to panicles per unit area(PPUA),plant height(PH),panicle length(PL),grains per panicle(GPP),seed setting rate(SSR)and grain weight(GW)based on grey relational grade analysis.The results showed that the ranking of the grey relational grades between the GY and the six agronomic characters of the twelve hybrid rice cultivars in descending order was PPUA(0.742),SSR(0.739),PL(0.705),GW(0.657),GPP(0.639),PH(0.614).Therefore,the breeding and cultivation of hybrid rice cultivars with appropriate PPUA,SSR and PL would be the main task in the future.关键词
