| Abstract: | Experiments from 1988 to 1990 led to the following results.Undcr thc radish CMS cytoplasmgenetic backgrounds,the additative genetic effects of the yellowing in Brassica campestris ssp.chinensis wasmore important than the partial dorminant effects.The broad and the narrow heredity were 87.6% and67.73%,respectively.Thus,it was thought that the yellowing of thc hybrids could be improved by allevi-ating the yellowing of the CMS line and scrccning the paternal genotypes obtusely sensitive to the yellowing.Effective improving the yellowing of the CMS lines could be attained by the pedigree selection in the lowergenerations and by changing their recurrent parents in the higher generations.10 suitable paternal cultivarswere screencd out and 4 of them with higher combine ability could be used for producing hybrids suitable forautumn or autumn-winter cultivating seasons. |
