本试验选用3个在黑龙江省大面积生产上推广应用的小麦品种,利用方差分析、线性回归、主效累加互作可乘模型以及产量与农艺性状、气候因子的相关性,分析3个小麦品种的丰产性、稳定性和适应性。结果表明:克旱16号丰产性、稳定性、适应性较好;对产量影响较大的农艺性状和气象因子分别为千粒重和平均气温;各试验点鉴别力最好的环境为2013年的拉布大林,即在此环境下最能表现不同品种的特征特性。
Three wheat cultivars that were widely used in large-scale production in Heilongjiang Province were selected in this experiment. The variance analysis, linear regression, multiplicative multiplication-multiplication model and the correlation between yield and agronomic traits and climatic factors were used to analyze the genetic diversity of three wheat cultivars The high yield, stability and adaptability. The results showed that the yield, stability and adaptability of Khan 16 were good. The agronomic traits and meteorological factors which had a great influence on the yield were respectively 1000-grain weight and average temperature. The best discriminating power for each experimental site was 2013 Bu Dalin, that is, in this environment can best show the characteristics of different varieties.
