不同结荚习性大豆品种综合生产力灰色关联度分析

Grey Relational Analysis of Comprehensive Productivity of Soybean Varieties(Glycine max) with Different Podding Habits

[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 99009-7Tie 00052-1Tie 00027-5Fu 05-148Liao 02 Pin-4-3-1Tiefeng No.33Liao 000045-2Tie 97118-2,while the weighted grade values was in order： Tie 99009-7Tie 00027-5Tie 00052-1Liao 000045-2Fu 05-148Liao 02 Pin-4-3-1Tie feng No.33Tie 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.
