The impact of waterlogging on phytophthora root rot resistance in chickpea

Abstract

Key findings •The level of waterlogging tolerance in Pulse Breeding Australia (PBA) chickpea material is minimal. •A source of phytophthora root rot (PRR) resistance in the wild Cicer backcross 04067-81-2-1-1(B) has positive waterlogging tolerance and outperformed the moderately resistant variety Yorker[PBR] and the susceptible Rupali[PBR] following two days of waterlogging and Phytophthora in combination. •In the presence of PRR (Phytophthora medicaginis), inoculum dry root weight decreased in the wild Cicer backcross by 26% (93.7 mg) after incurring an additional two days waterlogging, and 51% (62.3 mg) after six days waterlogging when compared to and inoculated control under normal soil moisture conditions (126.2 mg)
