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 annuumL.) with large fruit. The growth vigor and fruit
length of this innovated material 0516 (Tsw) has surpassed that of the
contrast. There are no significant differences in their commodity nature and
coordinate ability.

Sweet Pepper (Capsicum annuum L.) Germplasm Resource with Resistance to Tomato
Spots Wilt Virus delivered by researchers Wang Lihao, Zhang Zhenghai, Mao
Shengli, Cao Yacong, Du Meizhen and Zhang Baoxi from the Vegetable Research
Institute of the Academy of Agricultural Sciences.
