5个品种饲用玉米主要农艺性状评价
|
摘要
为引进和推广饲用玉米(Zea mays)提供理论依据,利用单因素方差分析和主成分分析对5个品种(科多四号、科多八号、BMS001、BMS002和中原单32)饲用玉米的10个主要农艺性状进行分析和评价。结果表明:饲用玉米各品种间农艺性状差异均达到极显著水平(P<0.05)。主成分分析得到的前2个主成分特征值的累积贡献率达到了90.02%,分别表示生产性能和营养生长的特点。通过第1和第2主成分值为坐标作图,得出BMS001和BMS002的综合性能表现最好。
In order to provide theoretical basis for introduction and extension the Zea mays,ten agronomic traits from five forage maize varieties(Keduo 4,Keduo 8,BMS001,BMS002 and Zhongyuandan 32) were evaluated by one-way ANOVA and principal component.Results showed that agronomic traits were significantly different among all of the five forage maize varieties(P<0.01).The component contributin rate of two extracted principal component factors was 90.02% in principal component analysis.The first and second principal component were productive performance and vegetative growth respectively.Coordinate drawing by means of first and second principal component values,the comprehensive performance of BMS001 and BMS002 were the best.
