Cataloguing variability in Phytophthora infestans with respect to ploidy status and response of different polyploids to temperature

Late blight, caused by the oomycete Phytophthora infestans, had been, and continues to be the most dreaded disease of potato and tomato world over. In the present study, P. infestans isolates collected from Indian hills, sub-tropical plains and plateau regions were analyzed for their ploidy status and results revealed that P. infestans population in the country are polyploid consisting of diploids, triploids and tetraploids. Diploids were...
