不同基因型大白菜耐湿性综合评价
Waterlogging tolerance of seventeen chinese cabbages of different genotypes
摘要
Abstract
Seventeen Chinese cabbage (Brassica rapa L. ssp. Pekinensis) of different genotypes were subjected to waterlogging stress to study the effects on some of the plant's yield traits and physiological indicators. Principal component analysis, subordinate function and system clustering analysis were used to evaluate the waterlogging tolerance of the 17 Chinese cabbages. The principal component analysis indicated that 11 indices could be categorized into 5 factors, with an accumulative contribution up to 0. 845. A comprehensive evaluation on the heat resistance was given based on D value of subordinate function analysis. The 17 genotypes were divided into 3 clusters by system clustering based on the D value. The most tolerant genotypes were Zao5-1-2-3, YMZ10-1 Baiyang-1 and Jingxia2-2-1 H. The moderately tolerant genotypes were Xiafu-2, Baiyang-2-5-3-2, XiaY-1 H, 001-3 S-8 H, Xia 001-4 S and Xiangyang-1. The least tolerant were Fu-2H, Ri-l-iH , llW-13H, 10W-18-2, Qingnong601-2jia, Bai15-5-3, Naire-8-1-3 and Zaoz-5.关键词
