| 为应对北疆热量资源不断增加的现状，筛选出适宜北疆地区种植的早熟高产复种大豆品种，采用单因素随机区组试验，以‘黑河45号’为对照品种，通过灰色关联度分析方法，对供试17个复种大豆品种进行生育进程、农艺性状、干物质积累及产量关系进行研究。结果表明：‘来豆1号’、‘合丰51号’、‘合交02-69’和‘合农114’生育时期天数为95～98 d，比对照品种延长13～16 d；株高和主茎节数显著高于对照品种，分别增加18.52%～37.85%和6.47%～17.80%；干物质积累量和产量均较高，平均产量为3 576.13 kg·hm-2，比对照品种增加3.83%。通过灰色关联分析发现，各品种农艺性状与产量的权重系数表现为主茎节数（0.1336）>株高（0.1325）>百粒重（0.1313）>单株粒数（0.1305）>单株荚数（0.1278）>茎粗（0.1272）>底荚高度（0.1116）>空腔数（0.1065），加权关联度的综合排名结果为‘合交02-69’>‘来豆1号’>‘合农114’>‘合丰51号’>‘合农77’>‘黑河45’>‘贺豆9号’>‘佳豆30’。从各品种的综合表现来看，‘来豆1号’、‘合丰51号’、‘合交02-69’和‘合农114’在早霜来临前能够成熟且获得较高产量，适合在北疆地区种植。 |

| To address the increasing heat resources in northern Xinjiang, early\|maturing, high\|yielding multiple\|cropping soybean varieties suitable for the region were selected. The growth process, agronomic traits, dry matter accumulation, and yield relationships of 17 multiple\|cropping soybean varieties were examined using a single\|factor randomized block design, with ‘Heihe 45’ as the control variety. Grey correlation analysis was applied to analyze the data. The results showed that the growth period days of ‘Laidou 1’, ‘Hefeng 51’, ‘Hejiao 02-69’ and ‘Henong 114’ were 95～98 days, 13～16 days longer than the control variety. The plant height and the number of main stem nodes were significantly higher than those of the control varieties, increased by 18.52%～37.85% and 6.47%～17.80%, respectively. The average yield was 3 576.13 kg·hm-2, which was 3.83% higher than the control variety. The weight coefficient of agronomic traits and yield of each variety showed as follows: number of main stem nodes (0.1336)>plant height (0.1325)>100-seed weight (0.1313)>seeds per plant (0.1305)>pods per plant (0.1278)>stem diameter (0.1272)>bottom pod height (0.1116)>number of cavities (0.1065). The comprehensive ranking results by weighted correlation degree were: ‘Hejiao 02-69’>‘Laidou 1’>‘Henong 114’>‘Hefeng 51’>‘Henong 77’>‘Heihe 45’>‘Hedou 9’>‘Jiadou 30’. Based on the overall performance of each variety, ‘Laidou 1’, ‘Hefeng 51’, ‘Hejiao 02-69’, and ‘Henong 114’ can mature and achieve high yields before the early frost, making them suitable for planting in northern Xinjiang. |
