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。
This experiment in the character of 8 wheat eultivars 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 eultivars with variant yield and the problem about improvement of the yield character of super-high-yielding wheat eultivars were discussed.
