摘要
大白菜对黑斑病抗性属数量遗传，由７～１０对以上基因控制，符合加性─显性模型。回交效应显著，表明主要为核基因遗传。亲本配合力ｇｃａ与ｓｃａ差异极显著，Ｆ值分别为１８０２及２９６，ｇｃａ／ｓｃａ＝６０７６。大白菜对黑斑病感病性与体内可溶性糖及ｖＣ含量呈显著正相关，ｒ值分别为０８９８及０９６０。
The resistance of Chinese cabbage to Alternaria brassicae falls into quantitative heritance and accords with additivedominant modelThe resistance controlled by 7～10 pairs of genes has lower genetic ability The backcross effect illustrates that the resistance is mainly nuclear heredityThe difference of parent gca and sca is extremely significance (F=1802,296)The susceptibility of Chinese cabbage to Alternaria brassicae is negetive correlation with the content of soluble sugar and vC in it The correlation coefficient is 08976 and 09599 respectively
