优质抗疫病甜椒种质资源的选育

Selection of Sweet Pepper Germplasm on Resistance to Phytophthora capsici L.

本文利用国外引进的2个抗疫病的商业品种,通过系谱法选择,获得了6个园艺性状普遍优于茄门、对疫病达到抗病和高抗水平的株系,其中有4个株系兼中抗CMV和TMV,另有1个株系兼抗CMV。其中2007903127和2008001329综合表现尤其突出。开展优质抗疫病甜椒种质资源的选育,将为国内抗疫病的甜椒育种起到积极的作用。

To develop new sweet pepper hybrid with resistance to Phytophthora capsici L., good breeding materials of sweet pepper with the resistance were scarce for a long period. In this study, using two introduced hybrids with the resistance, 10 lines with good agricultural characters and resistance to Phytophthora capsici L. were obtained by line method selection. Among them 6 lines have also resistance to CMV and TMV, and 1 line has resistance to CM V. Two of them （20079-0-3-1-27 and 20080-0-1-3-29） have outstanding agricultural characters and resistance. The sweet pepper germplasm we obtained would do great help on breeders to develop sweet pepper hybrids with resistance to Phytophthora capsici L..
