Abstract
In trials in 1976-7 the new tobacco cv. B 103 resistant to powdery mildew (Erysiphe cichoracearum) was compared with cv. Burley 21. Av. leaf yields for 3 sites in 1976 were 3.05 t/ha in B 103 and 3.22 t in Burley 21; comparable yields in 1977 were 2.81 and 2.97 t, resp. Plant ht. and leaf length were less in B 103 than in Burley 21.
