Plot trial introduction of spring wheat varieties (lines) , and yield varieties compare measured physiological indicators of drought characteristics , consolidated a number of indicators using fuzzy comprehensive evaluation method to evaluate screened adapt Xinjiang Arid Zone in the strong drought resistance and high yield varieties (lines) . The research results show that the analysis of variance and multiple comparison plot yield preliminary screening C16O and 8275 two drought resistance strong high yield varieties (lines) . This variety has a large biological yield , grain number and grain weight per spike higher characteristic . Leaf area changes of peak early, medium size , late to maintain higher leaf area . Physiological parameters were measured under drought conditions , the two varieties (lines ) showed high chlorophyll , leaf relative water content and more , proline accumulation , leaf water potential increase , reducing the cell membrane relative permeability characteristics , more drought-resistant performance . Use of fuzzy comprehensive evaluation method to the production of all varieties , and yield - related traits and physiological indicators together a comprehensive evaluation , sort varieties pros and cons , order : C160, 8275,8139,8624,8338, Dingxi 35 C4, sPRING , the Hoeryong 17 . Fuzzy Comprehensive Evaluation Method is a comprehensive , integrated , quantitative evaluation of the pros and cons of the spring wheat varieties , and the method is simple and effective , and high accuracy.
