Screening of cowpea genotypes for resistance against aphid, Aphis craccivora Koch

Field experiment carried out during Kharif 2024 under natural conditions for screening the cowpea genotypes for aphid resistance at Post Graduate Institute, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. Total twenty-one genotypes were taken for the experiment. The data from all twenty-one genotypes were collected and average was worked out. Also, the categorization of genotypes for resistance and susceptibility was done. The study showed that the genotypes PDKV Rutuja along with AKCP-18-2-1, AKCP-22-1-4, AKCP-19-1-1, AKCP-19-2-1, AKCP-24-1 were found resistance. The genotypes AKCP-18-5-4, AKCP-24-2, AKCP-18-4-3, AKCP-18-4-4 were found moderately resistant. The genotypes Konkan Sadabahar, AKCP-Divya and AKCP-18-5-2 were found highly susceptible with highest aphid infestation.
