The Correlation and Regression Analysis of Quantitative Characters in Crossing-Wheat

杂交小麦性状间相关、通径和回归分析表明,数量性状与株粒重的相关系数大小及趋势与中间型绵阳11品种基本相同。但杂交小麦具有明显的优势。由表1平均值比较可看出,杂交小麦的结实小穗数,主穗粒数,百粒重和株粒数比绵阳11有优势。从相关和回归关系看,杂交小麦具有绵阳11优良品种的株型结构,可以预料杂交小麦在大面积生产上推广,将有广阔前景。

The correlation and regresion analysis of quantitative characters in crossing-wheat shows that quantitative characters to grain weight of per plant have basic identification with Mianyang 11 of mesial-type breeds in affecting size and trend. But croosing-wheat possesses clear dominancy. From figure-1, mean comparison can make out: the effective spike number, the number of grains of main spike, the weight of 100 kernels and the grand grain number of per plant in comparison with Mianyang 11, express clear dominancy in crossing-wheat. From correlation and regrassion angls, crossing-wheat possesses Mianyang 11 structure of individualtype of good breeds. We may expect that popularization on the great area production of crossing-wheat will bring about broad prospects.
