Abstract:
The present study was made to evaluate fieldbean genotype for tolerant against fieldbean aphids. The experiment was conducted during 2017-18, at college of agriculture, IGKV, Raipur, Chhattisgarh. By growing a total of 118 genotype accessions on July, 2017 in an augmented design. It was found that out of 118 fieldbean genotypes, 5 genotype were recorded as a tolerant with overall mean per cent foliage drying between 21-25 per cent, 39 genotype were observed as a moderately tolerant comprised with overall mean infestation between 26-46 per cent infestation, 48 genotype were observed as a susceptible comprised with overall mean foliage drying per cent infestation between 50-64 per cent infestation and 26 genotype were observed as a highly susceptible comprised with overall mean foliage drying per cent infestation between 77-78 per cent infestation. The aphid population was lowest (6.64/cm length around pod) in the tolerant genotypes IS-37, followed by the genotypes IS-56 (6.92/cm length around pod) and IS-78 (7.48/cm length around pod) against aphids, respectively. Highest population was observed in the genotype IS-12 (18.31/cm length around pod) was highly susceptible, followed by the IS-18 (17.77/cm length around pod) and IS-88 (17.74/cm length around pod) against aphids.
