Selection and fixation in generations after backcross of the crosses for incorporation of resistance to Phytophthora capsici into Korean land races of pepper.

摘要

In a breeding programme to incorporate resistance to Phytophthora capsici into Korean landraces of pepper (Capsicum annuum), screening and selection for resistance was carried out in the BC1F3 to BC1F5 generations of the crosses Kalmi X PI201234, Punggak X PI201234 and Subi X PI201234, and in the BC2F2 to BC2F4 generations of the cross Kalmi X PI201234. Resistance to P. capsici appeared almost fixed in the BC1F5 generation. BC1F6 seeds of the three crosses and BC2F5 seeds of Kalmi X PI201234 were secured from BC1F5 and BC2F4 selections, respectively.
