为新疆大豆广适性品种的选育和改良提供理论依据,研究采用灰色关联分析法,在低纬地区对15份来自新疆的栽培大豆单株产量与主要农艺性状进行分析。结果表明,新疆大豆在低纬地区的单株产量与7个主要农艺性状的关联顺序为单株粒数>单株荚数>有效分枝数>株高>主茎节数>生育期>百粒重。得出单株粒数、单株荚数、有效分枝数是影响新疆大豆在低纬地区种植的重要因素。因此,在新疆大豆广适品种的选育过程中,应优先考虑单株粒数、单株荚数、有效分枝数等指标。
This study provides a theoretical basis for the breeding and improvement of wide adaptable soybean cultivars in Xinjiang, and studies the yield per plant and the main agronomic traits of 15 cultivated soybean cultivars from Xinjiang in low latitude by using gray relational analysis. The results showed that the order of association of single plant yield and seven main agronomic traits of Xinjiang soybean at low latitude was single grain per plant> pods per plant> number of effective branches> plant height> number of main stems> growth period> 100 Grain weight. The results showed that the number of per plant, number of pods per plant and number of effective branches were the important factors affecting Xinjiang soybean planting in low latitudes. Therefore, in the selection and breeding of soybean varieties in Xinjiang, priority should be given to individual grain number, number of pods per plant, number of effective branches and other indicators.
