The kinds of fertility genes and its genetic characters for D 2 type CMS lines of common wheat were studied, the results showed: (1) For D 2 type CMS line, there was wide restoring sources and high digree of restoration in common wheat varieties (the restoring digree of 33.

In order to resolving the problem that cross breeding in utilizing hybrid vigor by usingthe material of Multiple Allele inheritance green stalk cabbage as the source of the multiplealleles of male sterility, the experiment was designed to be the compound transfer anddirectional transfer scheme in studying on the method of Genetic male sterility(GMS) lines ofmilk Chinese cabbage.

This review focused on the progresses of study on CMS and restorer gene for fertility,such as the mitochondrial DNA locus found to be associated with CMS,the effects of restorer gene for fertility on the expression of the locus associated with CMS,the mapping with molecular marker and cloning of restorer genes for fertility of the CMS,and the molecular mechanis.

This review focuses on theprogresses of study on CMS in rapeseed fromfour aspects: (1) the mitochondrial DNA locusfound to be associated with CMS, (2) the effectsof restorer gene for fertility on the expression ofthe locus associated with CMS, (3) the mappingwith molecular marker and (4) cloning of restorergenes of fertility of the CMS in rapeseed.
