摘要: 高密度种植可以提高大豆产量,但通过改良株高及叶柄性状以选育株型紧凑、抗倒伏性优异的高产品种是提高产量的重要途径。2017-2018年,我们比较了黄淮地区四个地点的短叶柄种质M657与三个对照品种产量相关性状、抗倒伏性和叶柄相关表型间的关系。结果表明,M657对高种植密度和倒伏性表现出极高且稳定的耐受性,尤其在最高密度8×105株ha-1下表现依然优异。回归分析表明,较短的叶柄长度与抗倒伏性的增加显著相关。产量分析表明,M657在较高密度下获得了较高的产量,尤其在黄淮北片地区。在与地点、密度相关的倒伏性和产量方面,不同品种对株距、行间距的反应存在显著差异。植株的倒伏性与种植密度、株高、叶柄长度和有效分枝数显著正相关,与茎粗、单株粒数、单株粒重呈显著负相关。在当前大豆品种种植密度的基础上,适当增加种植密度有助于黄淮地区大豆的产量提高。本研究为在高密度种植系统中引入适宜高产的紧凑株型性状、建立黄淮地区大豆高产模式提供了极有价值的新种质资源。

Abstract:

Soybean yield has been increased through high planting density, but investigating plant height and petiole traits to select for compact architecture, lodging resistance, and high yield varieties is an underexplored avenue to improve yield.  We compared the relationship between yield-related traits, lodging resistance, and petiole-associated phenotypes in the short petiole germplasm M657 with three control accessions over 2017-2018 in four locations of the Huang-Huai region.  The results showed M657 exhibited stable and high tolerance to high planting density and resistance to lodging, especially at the highest density (8×105 plants ha-1).  Regression analysis showed that shorter petiole length was significantly associated with increased lodging resistance.  Yield analysis showed that M657 achieved higher yields under higher densities, especially in the north Huang-Huai region.  There are markedly different responses to intra- and inter-row spacing designs among varieties in both lodging and yield related to location and density.  Lodging was positively correlated with planting density, plant height, petiole length, and number of effective branches, and negatively correlated with stem diameter, seed number per plant, and seed weight per plant.  The yield of soybean was increased by appropriately increasing planting density on the basis of current soybean varieties in the Huang-Huai region.  This study provides a valuable new germplasm resource for introgression of compact architecture traits amenable to high yield in high density planting systems and establishes a high-yield model of soybean in the Huang-Huai region.
