[目的]综合评估不同结荚习性大豆(Glycine max)品种(系)的综合生产力表现,为大豆育种工作提供参考.[方法]用灰色关联度分析法对4个有限结荚习性大豆品种(铁99009-7、辽200045-2、铁00052-1、铁00027-5)和4个亚有限结荚习性大豆品种(铁97118-2、阜05-148、辽02品-4-3-1、铁丰33号)的主要农艺性状、光合速率、叶绿素含量和品质进行分析.[结果]等权关联度大小顺序依次为铁99009-7＞铁00052-1＞铁00027-5＞阜05-148＞辽02品-4-3-1＞铁丰33号＞辽000045-2＞铁97118-2；加权关联度大小顺序依次为铁99009-7＞铁00027-5＞铁00052-1＞辽000045-2＞阜05-148＞辽02品-4-3-1＞铁丰33号＞铁97118-2.所以有限结荚大豆品种铁99009-7综合表现最好,有限结荚大豆品种铁00052-1和铁00027-5次之,亚有限品种铁97118-2表现最差,其他品种居中.[结论]有限结荚习性品种综合表现优于亚有限结荚习性品种.%[Objective] The aim was to evaluate the comprehensive productivity performance of soybean varieties with different podding habits, and provide a reference for soybean breeding word. [Method] The main agronomic traits, photosynthetic rate, chlorophyll content and quality of four soybean varieties with limited podding habits( Tie 99009-7, Liao 200045-2, Tie 00052-1, Tie 00027-5) and four soybean varieties with sub-limited podding habits( Tie 97118-2, Fu 05-148 , Liao 02 Pin-4-3-1, Tiefeng No. 33) were analyzed by the grey relational analysis. [ Result] The equal relational grade values was in order; Tie 99009-7 > Tie 00052-1 > Tie 00027-5 > Fu 05-148 > Liao 02 Pin4-3-1> Tiefeng No. 33 > Liao 000045-2 > Tie 97118-2, while the weighted grade values was in order; Tie 99009-7 > Tie 00027-5 > Tie 00052-1 > Liao 000045-2 > Fu 05-148 > Liao 02 Pin4-3-1> Tie feng No. 33 > Tie 97118-2. So the limited podding habits soybean varieties Tie 99009-7 had the best comprehensive performance, Tie 00052-1 and Tie 00027-5 followed, while the sub-limited podding habits soybean varieties Tie 97118-2 showed the worst, the other soybean varieties was in the middle. [Conclusion] The comprehensive performance of the limited podding habits soybean varieties is better than that of the sub-limited podding habits soybean varieties.
