The genus Oryza to which the cultivated rice (Oryza sativa L.) belongs has 24 wild species. These wild species are an important source of useful genes for resistance to various diseases and insect pests. Madhya Pradesh (India) is rich in rice germplasm resources. The wild rices collected from Chhattisgarh region during October-November, 1991 were evaluated for BPH resistance in October, 1993.
