重庆地区生态条件下的油菜产量与农艺性状相关性分析

根据2009-2011年重庆市23个油菜品种区试的试验数据，利用SPSS统计分析软件，分析油菜产量与主要农艺性状之间的相关性。结果表明：油菜主要农艺性状对产量的作用大小依次为全株角果数〉株高〉每果粒数〉千粒重〉一次有效分枝数〉一次有效分枝高度；全株角果数和株高均与单株产量呈极显著正相关；株高和全株角果数之间呈极显著正相关；全株角果数和株高高效地控制着油菜生产力。

Correlation Analysis of Rape Yield and Agronomic Traits in Chongqing Ecological Condition

The annual total of 23 varieties of test results, 2009--2011 rape regional trial in Chongqing, the use of SPSS statistical analysis software, made on correlation analysis for yield and agronomic traits, the results show that： pods/ plant〉plant height〉the seeds of per silique〉 1000-grain weight〉the number of primary effective branches〉the height of primary effective branch, pods/plant and plant height were very significantly correlated with the yield of single plant respectively; plant height was very significantly correlated with pods/plant; pods/plant and plant height efficiently control the rape productivity.
