摘　　要：【目的】筛选适宜于新疆南疆推广种植的高产夏播大豆品种,挖掘与夏播大豆产量密切相关的农艺性状。【方法】2021年在新疆喀什地区泽普县进行复播大豆不同品种田间比较试验,采用田间试验灰色关联度分析方法,研究供试的23个夏大豆品种的主要农艺性状与产量关系。【结果】吉育354产量最高3271.05 kg/hm^(2),其次为吉育260为3154.35 kg/hm^(2)和吉育554为3066.75 kg/hm^(2)。大豆产量与主要农艺性状的关联度由大到小依次排序为株高(0.731)>百粒重(0.714)>底荚高(0.699)>荚节数(0.678)>单株粒数(0.669)>单株荚数(0.646)>茎秆直径(0.636)>单株粒重(0.633)>种植密度(0.625)>生育期(0.614)>主茎分枝(0.611)。【结论】适宜于新疆南疆地区种植的夏播大豆品种为吉育354、吉育260和吉育554,与新疆夏播大豆产量密切相关的农艺性状主要为株高和百粒重。【Objective】【Objective】In order to select the high-yield summer sowing soybean varieties suitable for planting promotion in southern Xinjiang,the agronomic traits closely related to the summer sowing soybean yield were excavated.【Methods】In 2021,the field comparison test of different replanted soybean varieties was conducted in Zepu County,Kashgar region,and the gray correlation analysis method was used to study the main agronomic traits and yield relationship of 23 summer soybean varieties.【Results】The highest yield of Jiyu 354 was 3,271.05 kg/hm^(2),followed by Jiyu 260 at 3,154.35 kg/hm^(2) and Jiyu 554 at 3,066.75 kg/hm^(2).The correlation between soybean yield and major agronomic traits was ranked from large to small as:plant height(0.731)>100 grain weight(0.714)>bottom pod height(0.699)>pod number(0.678)>Single seed number(0.669)>individual pod number(0.646)>stalk diameter(0.636)>individual seed weight(0.633)>planting density(0.625)>reproductive period(0.614)>main stem branch(0.611).【Conclusion】The summer sowing soybean varieties suitable for planting in southern Xinjiang are Jiyu 354、Jiyu 260 and Jiyu 554,the agronomic traits closely related to the yield of summer sowing soybean in Xinjiang are mainly plant height and hundred grain weight.
