【摘要】 通过鉴定15份大豆品种的主要农艺性状及分析相关性，旨在为新乡市大豆生产和品种选育提供理论参考。运用变异分析、相关性分析等方法，对15份大豆品种的7个农艺性状进行综合分析。结果表明：15份大豆品种有效分枝数的变异系数最大，单株有效荚数次之，遗传变异丰富，主茎节数变异系数最低，最为稳定；单株平均粒重与单株粒数、单株有效荚数呈极显著正相关，与有效分枝数呈显著正相关，与株高呈极显著负相关。更多还原

【Abstract】 This paper aims to provide a theoretical reference for soybean production and variety selection in Xinxiang City by identifying the main agronomic traits and correlation analysis of 15 soybean varieties. Variation analysis, correlation analysis and other data analysis methods were used to comprehensively analyze the 7 agronomic traits of 15 soybean varieties. The effective branches of 15 soybean varieties had the largest coefficient of variation, followed by effective pods per plant with abundant genetic variation, the variation coefficient of the number of main stem nodes was the lowest and the most stable. The average grain weight of a single plant was positively correlated with the number of grains per plant and the number of effective pods per plant, positively correlated with effective branches, and negatively correlated with plant height.更多还原
