应用主成分和隶属函数分析对国内20种大豆基因型的耐低磷能力进行评价,结果表明:11个差异显著的耐低磷评价指标通过主成分分析归纳为地上部分生物量因子、磷因子、根系因子3个主成分;供试基因型耐低磷由强到弱的顺序为:赶泰、五河齐黄豆、7650、湘豆4号、先进2号、苏88M-21、Peking、高作选1号、科丰一号、新沂小黑豆、南农1138-2、94-156、87-23、菏84-5、波高、RN-9、通山薄皮甲、皖82-178、湘秋豆2号、垫江早黄豆。 Principal component analysis and membership function analysis were used to evaluate the tolerance of 20 soybean genotypes to low-phosphorus stress. The results showed that eleven significant markers of low-phosphorus tolerance were summarized as aboveground biomass, phosphorus, Root elements of the three main components; test genotypes from low to strong phosphorus to strong to weak order: catch Thai, Wuhe Qi soybeans, 7650, Xiang Dou 4, Advanced 2, Su 88M-21, Peking, No. 1 Branch, Kefeng, Xinyi small black beans, Nongong 1138-2,94-156,87-23, He 84-5, wave height, RN-9, Tongshan thin leather armor, Anhui 82-178, Hunan autumn beans 2, Dianjiang early soybeans.
