Identification of novel sources for resistance against ascochyta blight and botrytis grey mould of chickpea

Abstract

Ascochyta blight (Ab) and botrytis grey mould (bGM) are the major foliar diseases of chickpea that can cause severe yield losses. Thus, to identify stable sources, a set of 388 lines including 288 lines from Reference Set of chickpea and 100 advanced breeding lines were screened at PAU, Ludhiana for two years against Ab and bGM. One accession, ICC 1915, from the Reference Set and 24 advanced breeding lines were found resistant against Ab. None of the lines was found resistant against bGM, however, some lines were found moderately resistant. The identified lines can be used as sources of resistance in the disease resistance breeding programmes.
