Damping-off Resistance in Chickpeas

Abstract

Association of resistance to preemergence damping-off caused by Pythium ultimum and gene P for flower and seed coat color was studied in two crosses of chickpeas (Cicer arietinum), kabuli line C 104, and desi lines T3(GW) and P 436-2 made at ICRISAT, Patancheru, India. Evaluations were performed under greenhouse conditions. Resistance was found to be inherited polygenically. Gene P appeared to be closely linked to the resistance. Kabuli segregants with reduced susceptibility were identified in both crosses, which indicates that linkage between gene P and genes for resistance to P. ultimum can be broken
