Abstract
Tissue cultures derived from stems of tobacco (N. tabacum) plants either susceptible to races 0 and 1 of P. parasitica var. nicotianae ''Burley 21'' or with resistance to race 0 derived from N. longiflora ''L8'' were inoculated with race 0 or 1 of the pathogen. Tissue cultures derived from ''Burley 21'' plants were susceptible to both races; cultures derived from ''L8'' plants were resistant to race 0 and susceptible to race 1. These results correlate with the reactions of stems or roots of these cultivars to races 0 and 1 and provide further evidence of the similarity of black shank resistance of N. longiflora and N. plumbaginifolia.This publication has 1 reference indexed in Scilit:
