Breeding of resistant cabbage 'CT-171' to Fusarium Wilt.

A new resistant cabbage variety 'CT-171' to Fusarium wilt was bred by crossing with resistance to the disease and 397- 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.
