| In order to cultivate new wheat varieties using available resourses more rapidly and efficiently in south mountain of Ningxia province, the study was carried out to identify the 12 traits of 8 varieties by the methods of drought resistance coefficient, principal component analysis, correlation analysis and cluster analysis. The results showed that ,according to the different drought resistance coefficient, 8 varieties can be divided into strong, middle and weak three grades. and the main information of the 12 traits was mainly concentrated in 4 principal components. The cumulative contribution rate was 93.40%. The main component factors mainly reflected yield, drought resistance coefficient, ear length, number of grains per spike, 1000-grain weight, grain weight per plant, plant height, number of panicles untrue, and spikelet seed setting rate. There was significant or very significant positive correlation between yield , panicle length, plant height, and drought resistance coefficient. The eight varieties were clustered into three categories The first category contains three varieties, including Z0217-3,Z0231-3 and CK(Zhongyin 6) the main indicators of yield, drought resistance, panicle length, 1000-grain weight and plant height and other major indicators of this category was between the third and second categories, but the spike length, number of grains per panicle, and grain weight per plant were the lowest among the three categories. The second category contains two varieties, in cluding 98-5808-1 and Z0228-2-1, the average values of the number of grains per spike, plant weight per plant, and number of false spikelets were the highest, but the average values of yield, drought resistance coefficient, panicle length, 1000-grain weight and other indicators were the lowest. The third category contains three varieties, including Z0349-4, 08AWS089 and Jintai 0509, the average of the three cultivars of yield, drought resistance coefficient, panicle length, the number of spikelet ,the largest grain weight, the plant height were the largest, This study will provide a theoretical basis for wheat parental selection and drought resistance breeding. |
