Abstract
One hundred and twelve accessions of lentil (Lens culinaris Medik) were screened for tolerance to black aphids (Aphis craccivora Koch) and some morphological attributes were recorded to find the association with aphid incidence. There was substantial variability observed for field infestation against aphids in lentil. A total of 27 accessions were found tolerant to aphids, 38 were highly susceptible and the rest were moderately resistant. Pearson Chi Square contingency analysis indicated that leaf pubescence and foliage colour had significantly contributed towards aphid infestation. Growth habit and days to flowering had shown significant association but with lesser degree while there was no significant role of biomass. Low infestation of aphids was observed on genotypes with green or yellowish green foliage and slightly pubescent leaves. Moderate infestation was recorded in genotypes with dark green foliage while genotypes with ash green foliage and densely pubescent leaves were highly susceptible to aphids.
