应用灰色关联度分析方法 ,对乌什垦区冬小麦产量与 10个性状的关联度进行了分析。结果表明 :关联度大小依次为千粒重r6 >收获穗数r7>单穗重r5 >粒质r8>株型r3>穗长r2 >穗粒数r4 >生育期r10 >株高r1>抗倒性。与产量形成关系密切的主要性状为千粒重、收获穗数、单穗重 ,并明确了各性状之间的相互关系 ,为小麦及时更替提供依据
Gray correlation analysis method was used to analyze the correlation between winter wheat yield and 10 traits in the area of Wushi reclamation area. The results showed that the degree of correlation was in the order of 1000 - grain weight r6> harvest panicle r7> single spike weight r5> grain r8> plant type r3> spike length r2> number of spike grains r4> growth stage r10> plant height r1> lodging resistance. The main traits closely related to the yield were the 1000-grain weight, the number of ears harvested, the weight of a single ear, and the relationship between the traits was clarified to provide a basis for the timely replacement of wheat
