摘要
该研究以哈密地区30个春小麦品种(系)为参试品种(系),对其12个农艺性状进行了主成分分析。结果表明:生育期、最高总茎数、收获穗数3个农艺性状是影响哈密地区春小麦产量的主要因子,当春小麦品种(系)生育期较低、最高总茎数适中,收获穗数较高时,春小麦较易获得高产;主成分分析得出,前3个主成分累计方差贡献率达99.83%,初步筛选出综合性状较好的品系3个为A4、A8、A14。
30 Spring Wheat Varieties（lines）were used as the experimental object,principal component analysiswas carried out on 12 agronomic characters. The results showed that there were 3 main factors affecting the yield ofspring wheat in Hami area. When the growth period was shorter,the highest total stem number was moderate,thenumber of spike and the rate of spike were higher,spring wheat varieties（lines）was easy to obtain high yield. The 3 traits of the cumulative contribution rate reached 99.83%,3 strains were screened out according to comprehensivetraits.
