不同类型大麦品种间杂交若干性状的相关分析

Correlation Analysis on some characters by Different Types Barley's Intervarietal Crossing

用简单相关分析方法，对不同类型大麦品种间杂交获得的12个世代的15个生育期和经济性状进行分析。验证了大麦幼穗分化开始比小麦早的观点，提出了拔节—孕穗是有效分蘖的关健时期。各经济性状间相关系数也得到分析，为大麦栽培和育种提供了依据。

Through simple correlation analysis about fifteen growth periods and economicalcharacters of twelve generations acquired by different types barley's intervarietal crossing, thepaper identied the viewpoint that barley's panicle-differentiation stage is earlier than wheat' s,and put for ward elongation-booting stage is crucial for effective tillering. In the meanwhile, thecoefficients of correlation among economical characters also were analysed to offer evidence forbowley'cultivating and breading.
