Ali, M.S.
The reaction on 14 varieties/lines of cotton (Gossypium sp) were studied against 17 different diseases in field condition under natural infection. Each variety/line showed different degrees of susceptibility and resistance to different diseases. The variety DPY/1 was found to suffer least degrees of susceptibility to various diseases than the rest. Kandwa/2 and 2421Y were also found promising in respect of disease resistance and disease avoidance. All the varieties/lines studied were highly susceptible (HS) to leaf spot disease caused by Alternaria sp and resistant (R) to foot rot and wilt disease.
