不同品种复播大豆产量与农艺性状的灰色关联度分析

Grey Relational Analysis of Yield and Agronomic Traits of Different Varieties of Summer Soybeans

【目的】筛选适宜于北疆推广种植的高产复播大豆品种。【方法】2013年在伊宁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,对供试的8个夏大豆品种的主要农艺性状与产量关系进行研究。【结果】黑河35号产量最高达3 160.7 kg/hm2,其次为黑河45号为3 081.17 kg/hm2和黑河43号为2 973.43 kg/hm2。大豆产量与主要农艺性状的关联度由大到小依次排序为:单株粒重>单株粒数>百粒重>主茎节数>荚数>株高>茎粗>空腔数。【结论】适宜于伊犁地区种植的复播大豆品种为黑河35号、黑河45号和黑河43号。

[Objective] In order to screen out summer soybean varieties that will be suitable for planting in the filed, we designed a comparative field trials for different varieties summer soybean in Yining County in the year 2013. [ Method] We studied the relationship between main agronomic traits and yield of the 8 summer soybean varieties which were tested by field trials and gray correlation analysis method. [ Result] The results showed that the highest yield of Heihe 35 was 3160.7kg/hm^2, followed by Heihe 45 to 3,081.17 kg/hm^2 and Heihe 43 to 2,973.43 kg/hm^2. Correlation degrees of yield and main agronomic traits were in descending order： grain weight of per plant 〉 plant grains 〉 kernel weight 〉 main stem section 〉 pod 〉 height 〉 stem diameter 〉 cavity number. [ Conclusion ] Under the experimental conditions, summer soybeans which suited for planting in the Ili area were Heihe 35, Heihe 45 and Heihe 43.
