Two hundred twenty nine isolates of Magnaporthe grisea were collected from finger millet cultivars at 14 locations in north India (Uttarakhand) and two locations in south India (Tamilnadu&Karnataka). Each isolate was tested for the mating types (Male fertile and female sterile) using standard fertile testers. Per cent isolates that neither mated nor produced perithecia was high among isolates collected from south India than those from Uttarakhand. Male fertile and hermaphrodite isolates from cooler region showed greater efficiency to produce perithecia. Results revealed that distribution of mating type varied with geographical region. Male fertile and female sterile isolates segregated in 1:1 ratio among field isolates collected from both north and south India. Field isolates from north India showed equal probability of getting male fertile, female sterile and hermaphrodite isolates, which suggested that probability for sexual reproduction in the population of M. grisea existed in nature in the central Himalayas of India.Keywords
