Abstract:

Pigeonpea (Cajanus cajan L. Millsp) is the most important grain legume grown in India. The crop is affected at various stages of the crop. Among the biotic stress stresses, Alternaria blight, caused by Alternaria tenussima is one of the most important foliar diseases of pigeonpea. Management of this disease through chemicals pesticides is not feasible and it affects the human, animal and ultimate causes the environmental pollution. Hence, considering host plant resistance (HPR) is one of the most important tools in managing this disease and reducing the yield losses of pigeonpea caused by Alternaria tenuissima. One hundred six genotypes of pigeonpea were obtained from the Department of Genetics and Plant Breeding, N.D. University of Agriculture and Technology (Kumarganj), Faizabad (U.P.) and screened at University Research farm for their reaction to Alternaria tenuissima under natural and artificial inoculated conditions by spraying inoculums (15-20 conidia/microscopic field). The genotypes were screened by 1-9 scale disease rating scale. Out of 106 genotypes, seven genotypes viz. Path 402, Path 407, NDA14-4, NDA14-15, NDA-14-16, NDA-14-29 and NDA-14-36 were found resistant, 33 genotypes were found moderately resistant, 53 genotypes were found moderately susceptible and 13 genotypes were found susceptible to Alternaria blight. The most susceptible variety Bahar showed 100 percent blighting. Resistant lines can by exploited in resistant breeding programme.
