摘要
为筛选出适宜鲁西北地区推广种植的优质高蛋白大豆,采用模糊隶属函数及主成分分析对参试10个高蛋白大豆品种的生产性能进行综合评价。结果表明,参试大豆品种分枝数、百粒重、底荚高度、产量和株高变异系数较大,主茎节数、单株荚数和单株粒数变异系数较小,且分枝数与株高、主茎节数均呈显著负相关,与单株荚数呈显著正相关,单株荚数和单株粒数之间,百粒重和产量之间均呈显著正相关。因此,在本地区选育高产品种时,应适当选择分枝数多、单株荚数多、单株粒数多和百粒重大的品种。通过隶属函数和主成分分析,冀豆12、齐黄34和菏豆37综合得分较高,产量也高,在鲁西北地区适应性强,可作为该区推广种植的优选高蛋白品种。
In order to select high-quality and high-protein soybean suitable for planting in northwest of Shandong,fuzzy membership function and principal component analysis were used to evaluate the production performance of 10 high-protein soybean varieties.The results showed that the coefficient of variation of branch number,100-seed weight,bottom pod height,yield and plant height were larger,but the coefficient of variation of main stem node number,pod number per plant and seed number per plant were smaller.The number of branches was negatively correlated with plant height and node number of main stem,and positively correlated with the pods number of per plant.There were significant positive correlations between pod number and grain number of per plant,as well as between 100-grain weight and yield.Therefore,varieties with more branches,pods and grains per plant,100-grain weight should be appropriately selected when breeding high-yield varieties in this region.According to the membership function and principal component analysis,Jidou 12,Qihuang 34 and Hedou 37 have high comprehensive scores and high yield,which has strong adaptability and can be used as the preferred high-protein variety for planting in northwest of Shandong.
