Abstract

In an effort to breed lines resistant to both bacterial wilt and Phytophthora blight, F5 and BC1F4, and F6 and BC1F5 generations of the crosses between the lines previously bred for resistance to Phytophthora blight ((16-2-2-3-2 = Phytophthora-resistant 'Kalmi', 19-1-3-7-1-1, 19-2-4-5-3-2 = Phytophthora-resistant 'Subi', Kim et al., 1996) and sources of resistance to bacterial wilt (KC350 = MC-4 or KC353 = PBC631, Kim et al., 1998) were evaluated for resistance to both bacterial wilt and to Phytophthora blight in 1999 and in 2000, respectively. Plants which were highly resistant to both bacterial wilt and Phytophthora blight were selected for development of the next generations.

풋마름병과 역병에 복합저항성인 계통을 육성하기 위한 노력으로서 앞서 역병 저항성으로 육성한 계통(16-2-3-2 = 역병 저항성 '칼미초', 19-1-3-7-1-1, 19-2-4-5-3-2 = 역병 저항성 '수비초', 김 등, 1996)과 풋마름병 저항성 계통(KC350 = MC 4, KC353 = PBC631)을 교배하여 육성한 $F_5$$BC_1F_4$, $F_6$$BC_1F_5$ 세대에 대해 1999년과 2000년에 각각 풋마름병과 역병에 대한 복합저항성을 검정하였다. 풋마름병과 역병에 복합 저항성을 보인 개체를 선발하여 다음 세대의 종자를 채종하였다.
