摘要
选用 4 0个小麦品种 (系 ) ,运用方差分析、产量构成分析、生物产量分析等方法 ,对供试品种的 11个主要农艺性状进行比较分析 ,以探讨小麦主要农艺性状协调性对单株产量的影响。结果表明 ,小麦品种 (系 )的这些性状与产量因素之间是相互制约、相互促进、协调发展的 ,不能片面追求单一目标性状的提高 ,而忽略品种其它性状的协调性。在育种工作中 ,既要注重某一优良性状 ,又要兼顾其它性状 ,考虑各优良性状的内在联系 。
Using 40 Cultivars (lines), the effect of coordinating activity among 11 major agronomic traits on the grain weight per plant in wheat was studied. The comparison of traits among different wheat cultivars(lines)were discussed with the analytic methods of variance in yield components and biomass. The results showed that the relations among all traits in wheat was in limiting and development each other so a single trait should not be raised without consideration of other traits. Not only a elite trait should be considered, but also other traits and their relations should be regarded. The development of all relative traits is the best method in increaring the yield of wheat cultivar.
