Selection procedures for breeding genic male sterile lines for resistance to both Phytophthora blight caused by Phytophthora capsici and bacterial spot caused by Xanthomonas euvesicatoria were executed to and generations derived from a cross between a Phytophthora resistant genic male sterile (GMS) breeding line and a bacterial spot and Phytophthora resistant breeding line. Resistance to P. capsici was originally introduced from KC294(CM334) and KC263(AC2258), the well-known sources of resistance to P. capsici. Resistance to bacterial spot was introduced from KC47(PI244670). GMS lines with high resistance to P. capsici were obtained and the selected lines are expected to be quantitatively resistant also to bacterial spot.

역병(Phytophthora capsici)과 세균성점무늬병(Xanthomonas euvesicatoria)에 복합저항성인 핵유전형 웅성불임계(Genic male sterile line, GMS)를 육성하기 위하여 역병 저항성 핵유전형 웅성불임계에 역병-세균성점무늬병 복합저항성 계통을 교배하여 작성한 조합의 와 세대에 대하여 두 가지 병에 대한 저항성 선발을 실시하였다. 역병 저항성은 잘 알려져 있는 KC294(CM334)와 KC263(AC2258)에서 도입하고, 세균성점무늬병 저항성은 KC47(PI24467)에서 도입되었다. 역병에 고도의 저항성을 지닌 GMS 계통이 얻어졌으며, 이들은 세균성점무늬병에도 양적으로 저항성을 나타낼 것으로 기대된다.
