Identification and Comprehensive Evaluation of Drought Resistance of Different Foxtail Millet during Germination
Multiple indexes of different varieties/lines of foxtail millet under drought stress were comprehensively analyzed to provide theoretical basis for drought resistance mechanism and germplasm resources for drought resist-ance of foxtail millet.The physiological indexes of 12 varieties/lines of foxtail millet were measured under different treatment conditions,and the drought resistance of 12 varieties of millet was evaluated by membership function a-nalysis,correlation analysis and cluster analysis.The results showed that different varieties/lines of millet had dif-ferent levels of drought resistance to a single index.According to drought resistance measurement value,the drought resistance of 12 varieties/lines of foxtail millet could be divided into three categories.The first category was Yugu 18 and lines 155,312 and 244 with strong drought resistance.The second category was the medium drought resistance strains 134,154,185,230,239,273 and 291.The third category was strain 199 with weak drought resistance.The results showed that CAT,germination rate and biological weight had good correlation with comprehensive drought resistance index,and were important reference indexes for evaluating drought resistance of millet during germination.
