摘　　要：番茄斑点萎蔫病毒病是我国辣椒生产的一种新兴和潜在重大威胁病害。利用引进的中国辣椒(Capsicum chinense Jack.)抗源材料PI152225,通过种间杂交和分子标记辅助回交选育,历时10年,将抗性基因Tsw转育到中椒系列骨干亲本一年生辣椒(Capsicum annuum L.)大果甜椒自交系0516中,创新材料0516(Tsw)的生长势和果实长度超过对照0516,商品性和配合力与骨干亲本0516差异不显著。Tomato spots wilt virus is a serious disease affecting pepper production in China.It is also a new and high potential threat to pepper production.Using resistant material PI152225 of imported pepper（Capsicum chinense Jack.）,this study has conducted backcross via interspecies crossing and molecular markers assisted breeding for 10 years,and successfully introduced the resistant gene Tsw into the inbred line 0516 of sweet pepper（Capsicum annuum L.） with large fruit.The growth vigor and fruit length of this innovated material 0516（Tsw）has surpassed that of the contrast.There were no significant differences in their commodity nature and coordinate ability.
