Occurrence of Phytophthora blight of cowpea in Madhya Pradesh and evaluation of genotypes for field resistance
208 / 76
Abstract
A cowpea (Vigna unguiculata) blight disease observed during the rainy season in Madhya Pradesh, India, was identified as Phytophthora vignae. Following identification, 51 cultivars/lines were screened for their reaction to P. vignae at Jabalpur during 1996-97. None of the entries was resistant to the disease and only IFC-9502 was moderately resistant. All the other entries were moderately susceptible (UPC-601, UPC-942 and UPC-5286) or highly susceptible (47).
