Breeding ‘Chinese Cabbage Parental Line Nou-6’ with Bolting Resistance

Abstract

‘Chinese Cabbage Parental Line No.6’ is selected from a cross between Chinese cabbage and lage bolting turnip. Its bolting resistance is due to low sensitivity to low temperature. This line showed high marketability when other bolting-resistance cultivars could not be harvested because of early bolting. No.6 is to be abole to use for bolting-resistant Chinese cabbage breeding, because more than 10% of bolting resistant individuals were observed in the F₂ segregated population. It may facilitate more stable cultivation of spring sown Chinese cabbage, saving both labor and energy.
