| 摘 要： | 玉米杂交种的综合评价是新品种选育、审定和推广的重要依据。以黑龙江省种植的部分玉米杂交种为试验材料,测定其产量（14%含水量）、籽粒含水量、容重、秃尖长、出籽率、轴粗/穗粗、百粒重和穗长8个性状,采用灰色关联度法对28个供试玉米杂交种的8个性状进行综合评价。结果表明,德美亚3号、先玉696和先玉335加权关联度排在前3位,综合表现好。

| Abstract: | Comprehensive evaluation of maize hybrids are an important basis for the breeding, certification, and popularization of new varieties. In this experiment, some maize hybrids planted in Heilongjiang province were used as experimental materials. Eight characteristics were measured such as yield (14% water content), grain water content, unit weight, bald tip length, cone rate of seed, axle diameter/ear diameter, 100-grain weight, and ear length using the grey correlation method to evaluate the tested 28 maize hybrids. The results showed that the first three of the weighted correlation degree of maize hybrids were Demeiya 3, Xianyu 696 and Xianyu 335, which had the excellent comprehensive performance. |
