| 摘 要： | 为明确间作大豆的性状表现，筛选适宜间作的高产、稳产性大豆品种，本研究在玉米大豆间作模式下，对50份大豆材料在两年的产量与11个主要农艺性状进行相关性及灰色关联度分析，并采用GGE双标图法进行品种适应性及稳产性分析。结果表明：50份材料的主要农艺及产量性状的变异系数在6.87%~77.32%，广义遗传力为0.62~0.97，且生育期、营养生长期、百粒重等9个性状的广义遗传力均大于0.8；相关性分析表明，单株产量与茎粗(0.75**)、生育期(0.76**)呈极显著正相关，其次为株高、主茎节数、分枝数、底荚高、营养生长期、百粒重、单株荚数、单株粒数；灰色关联度分析表明，单株产量与各农艺性状的关联顺序为茎粗>生育期>营养生长期>单株荚数>百粒重>底荚高>单株粒数>分枝数>主茎节数>株高>生殖生长期；GGE双标图法表明汾豆79、中作J7018和皖豆30为适宜间作的高产、稳产性较好的品种。

| Abstract: | In this study, the characters of intercropping soybean were identified with an aim to screen high yield soybean germplasms for intercropping pattern. The correlation between yield traits and 11 agronomic traits of 50 soybean materials were analyzed by grey correlation degree analysis, and their adaptability and yield stability analyzed by GGE-biplot method. The results showed that the variation coefficients and the generalized heritability of agronomic and yield traits were 6.87%-77.32% and 0.62-0.97 in two years respectively. Generalized heritability of 9 characteristics was greater than 0.8, such as growth period, vegetative growth stage and hundred-grain weight. The correlation analysis showed that the yield per plant was significantly positively correlated with stem diameter, growth period, plant height, node number, branch number, bottom pod height, vegetative growth, 100-seed weight, pods per plant, seeds number per plant. The grey correlation degree analysis showed that the order of the correlative degree of main characteristics to yield was stem diameter > growth period >vegetative growth > pods per plant > 100-seed weight > bottom pod height > seeds number per plant > branch number > node number on main stem > plant height > reproductive growth period. GGE-biplot method analysis showed that Fendou 79, Zhongzuo J7018 and Wandou 30 were suitable for intercropping in Shandong. |
