Association of green islands with rice blast lesions and its utility in varietal screening



Association of green islands with rice blast lesions and its utility in varietal screening



Current Science, India 56(4): 192-193



Lesions produced on the leaves of resistant varieties (e.g. Rambhog, Zapaka, Taichung and Phudunge I) following infection by Pyricularia oryzae were small, dark and not associated with the production of 'green islands' of uninfected tissue. Lesions produced on the leaves of 11 susceptible varieties varied in colour and size, but green islands were always present.
