Inheritance of bolt resistance in an interspecific cross of Brassica species
II. Chikale (B. campestris L. ssp. pekinensis × B. napus L.) ×Chinese cabbage
Department of Horticulture, Michigan State University East Lansing, MI 48824
Abstract
The inheritance of bolting in Chinese cabbage (Brassica campestris L. ssp. pekinensis) was investigated by hybridization with Chikale (B. campestris L. ssp. pekinensis × B. napus L.). The two Chikale lines were developed by hybridizing Chinese cabbage cv. Mandarin with the kale cv. Siberian. The Chikale lines differed for bolting response with QB-2 bolting after one week of vernalization, and LB-7 bolting after four weeks of vernalization. Segregation for the bolting response from reciprocal crosses between the Chinese cabbage cv. Wong Bok and these two Chikale lines suggested two major additive genes with modifiers conditioned the bolting response.
