胶东半岛鲜食大豆种质资源产量及相关农艺性状分析

Adaptability Analysis of Different Vegetable Soybean Varieties in Jiaodong Peninsula Based on Their Yields and Yield-related Agronomic Traits

  • 摘要: 为筛选适合胶东半岛种植的鲜食大豆品种(系),本试验选取63个鲜食大豆品种(系)于2019—2021年进行田间种植,在鲜食期对13个产量相关农艺性状进行考查统计,并和鲜荚产量进行相关性和关联度分析。结果表明:参试品种(系)的各农艺性状变异系数在9.66%~86.53%之间;单株产量与节数、一粒荚数、标准荚数、单株荚数和标准荚长呈极显著正相关,与分枝数、空荚数和鲜重呈显著正相关,与株高、虫荚数、干重和标准荚宽呈不显著正相关。各性状与产量的关联度排行为单株荚数>单株荚重>鲜重>干重>有效分枝数>标准荚长>标准荚宽>主茎节数>标准荚数>株高>一粒荚数>空荚数>虫食荚数。对所有参试品种大豆(系)与理想品种(系)进行等权和加权关联分析,筛选出综合表现最优的7个品种,分别为辽鲜3号、晋豆39、南农29、辽08M13-1H、首豆38、引豆9701和南农95C-13,本研究为菜用大豆在胶东地区的推广和种植奠定了坚实的基础。

     

    Abstract: To obtain the varieties of vegetable soybean suitable for Jiaodong Peninsula. 63 vegetable soybean varieties from different areas were selected and sown in the field during 2019—2021 in this experiment.During the fresh-eating period, 13 agronoinic traits related to yield were investigated and their correlation with yield of fresh pods were canied out. The results showed that the variation coefficient was ranged from 9.66% to 86.53%. Except for plant height, the number of pods eaten by insects, dry weight and standard pod width, the yield per plant were significantly correlated with the other yield agronomic traits investigated. The order of correlation degree from high to low was: pod number per plant>pod weight per plant>fresh weight>dry weight>effective branches>standard pod length>standard pod width>main stem node number>standard pod height>plant height> one-pod number>the number of pods eaten by insects. By the equal weight and weighted association analysis, seven best varieties were selected, including Liaoxian 3, Jindou 39, Nannong 29, Liao08m13-1h, Shoudou 38, Yindou 9701, and Nannong 95C-13, which will establish a solid foundation for the popularization and cultivation of vegetable soybean in Jiaodong area. This study has laid a solid foundation for the promotion and planting of vegetable soybeans in Jiaodong region.
