| 摘 要： | 应用关联度分析法,研究了超高产小麦主要性状对产量的影响,结果表明产量与10个性状的关联序依次为容重r10＞穗粒数r7＞有效穗r6＞抽穗至成熟天数r2＞千粒重r9＞穗粒重r8＞全生育期r3＞株高r4＞最高分蘖r5＞出苗至抽穗天数r1,而且还明确了各个性状之间的关联程度,提出了超高产小麦的育种途径.

| Abstract: | The effects of main traits on the yield of superhigh yield wheat were studied by the method of grey correlative degree analysis.The results showed that the successive order of the correlative degree bewteen the yield and the every special trait is:Volume weight( r 10 )> Number of grains per ear( r 7 )>Effective ear( r 1) >Days from earring to maturity (r 2 )>1000-grain weight (r 9 )>Weight of grains per ear( r 8 )>The whole planting period (r 3 )>plant height (r 4 )>Largest number of tillers (r 5) >Days from seeding to earring (r 1) .The studies indicated the correlative degree among the different traits and presented the breeding approach of the superhigh yield wheat. |
