摘要

A new recessive genic male sterile dual-purpose line 20118AB which the ratio of fertility segregation is stable 1:1 and 3:1 by the sterile plants(ms1ms1ms2ms2RfRf) crossed with the fertile plants(Ms1ms1ms2ms2RfRf or ms1ms1Ms2ms2RfRf) and fertile plants selfed, respectively was found. The fertility of a sterile line of 20118A was contr olled by two pairs of recessive duplicate sterile genes(ms1ms1ms2ms2) and one pair of recessive epistatic fertile gene(rfrf). The genotype of the maintainer line was ms1ms1ms2ms2rfrf. The genotypes of the restorer line were Ms1Ms1__and__Ms2Ms2. Hybrid seeds can be produced by using this system. Firstly, the homozygous dual-purpose line was kept by sib-mating and the sterile line could be obtained by removal 50% fertile plants in the two-type line. Secondly, the full sterile line(ms1ms1ms2ms2Rfrf) could be produced by the cross between the sterile line and the maintainer line. Lastly, hybrid seeds were produced through the cross between the full sterile line and restorer line. Three double low hybrid varieties have been bred by Shanghai Academy of Agricultural Sciences using the system Up to 2006.
