Mapping of a gene for photoperiod-sensitive genic male sterility in Nongken 58s on chromosome 5 of rice

摘要

A photoperiod-sensitive genic male sterile(PGMS)rice was found in 1973 as a sponta-neous mutant of Nongken 58,a japonica vari-ety.Pollen fertility of Nongken 58s(N58s)iscompletely sterile when grown under long-dayconditions,whereas fertile under short-dayconditions.This PGMS was found to be con-trolled by one or two recessive gene(s),ofwhich one gene(pms)was linked to a markergene(d-1)on chromosome 5.In order to identify a more precise
