Abstract:

For investigating the cytoplasmic effects of cytoplasmic male sterility(CMS)on major agronomic and quality characters of cauliflower hybrids,six cauliflower sterile lines(A lines)with different cytoplasm from rape and cabbage,etc,and their maintainer lines(B lines)were used to make hybrids of A lines × test lines(AF 1)and B lines × test lines(BF 1). The effects were indicated by AF1-BF1 or (AF1-BF1)/BF1(relative effect). The results showed that significant positive effects were observed on days of curd appearing,days of curd harvesting,and vitamin C content. Comparison of cytoplasmic effects of different CMS sources,the rape cytoplasm had significant positive effects on growth period and number of rosette leaves. The cabbage cytoplasm showed significant positive effects on curd weight,lengthways diameter of curd,vitamin C content and days of curd harvesting,but a significant negative effect on chlorophyll content and number of rosette leaves. The cauliflower cytoplasm presented significant positive effects on growth period and vitamin C content. Comparison of cytoplasmic effects of the six cauliflower CMS lines which showed that NB65A had the highest positive effect on curd weight,lengthways diameter of curd,transverse diameter of curd and soluble sugar content,XG108A had the highest positive effect on cotent of vitamin C and soluble protein. Both of them could be used as the female parent for breeding high yield or high quality combinations. These results indicated that the cytoplasmic of different CMS sources of cauliflower showed complex effects on major agronomic and quality characters,and the adverse effects on some characters could be alleviated or overcome by nucleus of a appropriate male parent.
