| 摘 要： | 利用近10年来安徽省主要推广的8个高产小麦品种,针对影响小麦产量的单位面积穗数、穗粒数和千粒重等因素,通过方差分析、相关分析和通径分析,探讨三者之间的相互关系及其对产量的影响.结果表明,小麦产量水平的不断提高是其产量因素协调发展的结果.讨论了超高产小麦品种的产量构成因素与产量性状改良等问题.

| Abstract: | This experiment in the character of 8 wheat cultivars with higher yield in Anhui province in the 10 years lately was done to study on the three factors of yield component:number of panicle per unit area,grains per ear and thousand-grain weight,with variance analysis、correlation analysis and path analysis.Theresults showed that unceasingly enhancement of yield was a result of harmoniously development of the three yield components.The yield components of wheat cultivars with variant yield and the problem about improvement of the yield character of super-high-yielding wheat cultivars were discussed. |
