采用灰色关联度分析法分析了12个杂交稻品种(丰两优4号、杨农优3611、先农303、金优987、东优1388、丰优126、45S/RX10、荆楚优1537、Ⅱ优838、香优218、川香29A/AW03和SD-88)产量与单位面积有效穗数、株高、穗长、每穗粒数、结实率和粒重的关系.结果表明:12个杂交稻品种产量与6个农艺性状关联度的降序排列为:单位面积有效穗数(0.742)、结实率(0.739)、穗长(0.705)、粒重(0.657)、每穗粒数(0.639)、株高(0.614).由此可见,适宜的单位面积有效穗数、结实率和穗长可能成为今后杂交稻育种与栽培管理工作的主攻方向.

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.
