Abstract

A new resistant cabbage variety ‘CT-171’ to Fusarium wilt was bred by crossing A337MSBC5 with resistance to the disease and 397-G₆ with good density and color. ‘CT-171’ was selected after combining ability, seed gathering and regional adaptability test in 2008. For breeding of resistant varieties, we investigated the development of Fusarium wilt on cabbage seedlings inoculated with Fusariumoxysporum f. sp. conglutinans by root dipping inoculation method. As a result, ‘CT-171’ showed higher resistance to Fusarium wilt than ‘Asiaball’ used as control. The maturity of new variety was 58 days and was faster than control and well suited for autumn cultivation because of cold resistance. The anthocyanin pigment of plant was not revealed. The weight, height and width of head were 1.5 kg, 14 cm and 15 cm, respectively and the core size was 5.7 cm and stable in various cultivation environments. ‘CT-171’ which showed good agricultural character and resistance to Fusarium wilt filed for variety protect right in Korea Seed & Variety Service on February 2013. The new variety will be appropriate for export and domestic consumption.

시들음병에 저항성인 수출 및 국내용 양배추 품종을 개발하기 위해 시들음병 저항성 계통인 A337MSBC5를 모계로, 중국에서 수집하여 결구긴도와 구의 색이 우수하여 선발 고정된 397-G₆를 부본으로 선발하여 2008년부터 조합검정과 채종시험 및 지역적응성 시험을 거쳐 ‘CT-171’ 품종을 육성하였다. 시들음병 저항성 검정은 뿌리 침지법을 이용하여 저항성 정도를 검정하였고, 그 결과 ‘CT-171’ 품종이 대조품종인 ‘아시아볼’, ‘중감 11호’에 비해 더 강한 저항성을 보였다. ‘CT-171’ 품종은 숙기가 58일로 대조품종에 비해 숙기가 빨랐으며, 내한성이 강하여 가을작형에 적합하였고 안토시안발현이 없는 특성을 가지고 있었다. 구중은 1.5kg, 구고 14cm, 구폭 15cm, 고갱이가 5.7cm로 재배환경에 고갱이 길이가 크게 영양을 받지 않는 안정된 특성을 가지고 있었다. ‘CT-171’ 품종은 2013년 2월 국립종자원에품종보호권이 최종등록 되었으며, 원예적 형질이 우수한 시들음병 저항성 품종으로 해외 수출용 및 국내 수입대체용으로 적합할 것으로 판단된다.
