Abstract

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 CMV. 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..
