摘要
为筛选适宜兴安盟地区推广种植优质高产大豆品种,深挖与产量紧密相关农艺性状,文章运用相关性和灰色关联度分析方法,对30个大豆品种产量与9个主要农艺性状关系进行分析。结果表明,产量与9个主要农艺性状变异系数由大到小依次为有效分枝数>单株粒数>有效荚数>底荚高度>单株粒重>产量>百粒重>主茎节数>株高>生育期。底荚高度与有效荚数、单株粒数及单株粒重呈极显著负相关,与产量呈显著负相关;主茎节数与有效荚数、单株粒数及生育期呈极显著正相关;有效荚数与单株粒数及单株粒重呈极显著正相关;产量与单株粒重呈显著正相关。产量与主要农艺性状灰色关联度大小依次为单株粒重(0.7245)>单株粒数(0.6984)>有效荚数(0.6939)>有效分枝数(0.6906)>株高(0.6806)>主茎节数(0.6416)>百粒重(0.6358)>底荚高度(0.6350)>生育期(0.6243)。综上,在兴安盟地区对大豆产量影响最大为单株粒重,其次为单株粒数和有效荚数,适宜推广种植底荚高度低、主茎节数多大豆品种。
In order to select high-quality and high-yield soybean varieties suitable for promotion and planting in the Hinggan League area,the relationship between yield and nine main agronomic traits of 30 soybean varieties participating in field comparison experiment was analyzed by using correlation analysis and grey correlation analysis method.The results indicated that the coefficient of variation for yield and agronomic traits,arranged in descending order,was as follows:number of effective branches>number of grains per plant>number of effective pods>pod base height>grain weight per plant>yield>hundred-seed weight>number of main stem nodes>plant height>growth duration.The pod base height exhibited negative correlations with the number of effective pods,the number of grains per plant,and the grain weight per plant,and was also negatively correlated with yield.The number of main stem nodes was highly significantly positively correlated with the number of effective pods,and the number of grains per plant;the number of effective pods was highly significantly positively correlated with the number of grains per plant and the grain weight per plant;and the yield was significantly positively correlated with the grain weight per plant.The grey correlation degree between yield and the main agronomic traits was as follows:single plant grain weight(0.7245)>single plant grain number(0.6984)>effective pod number(0.6939)>effective branch number(0.6906)>plant height(0.6806)>main stem node number(0.6416)>hundred-seed weight(0.6358)>base pod height(0.6350)>growth period(0.6243).In conclusion,in the Hinggan League area,the factor that has the greatest impact on soybean yield was the weight of each individual grain,followed by the number of grains per plant and the number of effective pods.It was recommended to promote the cultivation of soybean varieties characterized by low bottom pod height and a high number of main stem nodes.
