The male sterility is this system is determined by one recessive genomic gene, given a 3:1 ratio from a heterozygote. In this present year, the project would be first focused on the screening and identification of molecular linked to the gene affected male sterility in this system. Any identified markers will be used to evaluate the likage between the marker and male sterility among other lines.辣椒雄不稔性一代雜種分子標誌hot peppermale sterilityF1 hybridmolecular marker辣椒雄不稔系統分子標誌之研究
