Identification of Sources Resistant to Dry Root Rot Caused by Macrophomina phaseolina (Tassi) in Chickpea (Cicer arietinum L.)

摘要

Dry root rot is one of the most important and widespread soil borne diseases of chickpea grown between latitudes 20° N and 20° S where, the climate is relatively dry and warm and is emerging as a serious biotic constraint for chickpea production. Inthis study, 815 germplasm accessions of chickpea collected from different research institutes representing significant diversity were screened for resistance against dry root rot (DRR) under a controlled environment using Blotter paper technique. In all, 7, 154, 436 and 218 accessions were moderately resistant, moderately susceptible, susceptible and highly susceptible to DRR, respectively. Seven chickpea germplasm accessions identified through this study possessing high levels of resistance to dry root rot disease viz., ICCV-07305, ICCV-06304, K-007, GNG-1499, GNG-1958, ICC-14699 and BGM-572 would be useful in chickpea disease resistance breeding programs.
