Study on Adaptability of Different Dryland Wheat Varieties in Guanzhong Region of Shaanxi Province
This experiment was conducted at the experimental base of the Baoji Academy of Agricultural Sciences,using 6 dryland wheat varieties(lines)as the research subjects.Through comprehensive analysis of yield and stress resistance,correlation and cluster analyses were carried out to select high-quality new wheat varieties suitable for planting in Baoji.The correlation analysis showed that the average yield was positively corre-lated with the maximum tillering,test weight,effective panicles,and grain number.There was a significant posi-tive correlation between the maximum tillering and grain number,and between the test weight and thousand-grain weight.The cluster analysis showed that the yields of'Pubing 017'and'Zhongmai 49'in Cluster I were 6 914.29 kg/hm2 and 6 535.71 kg/hm2,respectively,which were 16.0%and 9.6%higher than that of'Zhongmai 36'(control),showing significant effects in increasing production.Moreover,'Pubing 017'and'Zhongmai 49'exhibited strong stress resistance and favorable overall traits,which were suitable for planting in Guanzhong region of Shaanxi Province.
