摘　　要：为了探讨NEA细胞质相对效应,对选育出的甘蓝型细胞质雄性不育新材料NEA的不育胞质和可育胞质杂种F112个主要性状进行了比较研究。结果表明:考察的12个主要性状中,除主序角果数不育胞质杂种F1和可育胞质杂种F1t检验差异达5%显著水平外,其余11个性状2种胞质杂种F1t检验差异不显著;主序有效长、第一次分枝数、硫苷等3个性状的可育胞质与不育胞质间线性相关关系显著,其余9个性状的线性相关关系不显著;NEA不育胞质对多数组合的硫苷和千粒重有优良相对效应,对其余性状的相对效应则组合不同正负效应不同。说明NEA不育胞质对杂种一代主要性状无显著负效应,在产量和品质育种中应注意选择有较大优良相对效应的组合,更好地发挥其杂种优势。In order to study the effects of NEA male sterile cytoplasm on major characters of F1, the differences between the male sterile and normal cytoplasms of the NEA plants were investigated. The results showed that except pods of main inflorescence, the other characters of the sterile and normal cytoplasms had not significant difference by t test. The correlation coefficients of length of main inflorescence, No. of first time branches and glucosinolates between sterile and normal cytoplasms was at 5 percent significant level, but corrclation coefficients of the others was not significant. There were positive effects of male sterile cytoplasm on glucosinolates and weight of 1000 seeds, but different effects on the other characters when combinations were different. The conclusion was drawn that there were not negative effects of NEA male sterile cytoplasm on major characters of F1 ,the combinations which had distinct positive effects in yield and quality breeding in Brassica napus L. should be selected.
