Evaluation of horse gram germplasms for resistance to the root-knot nematode, Meloidogyne incognita

Horse gram is one of the lesser known beans. It is a legume of the tropics and subtropics, cultivated mostly under dry-land agriculture, especially in southern Indian states. The crop is susceptible to many viral diseases and fungal diseases. This crop is included in crop rotation program to minimize the root-knot nematode population in FCV tobacco cultivation. Of late, horse gram is noticed to be infected with root-knot nematodes. In a field trial 91 germplasms were evaluated against root-knot nematode for their resistant reaction. Fourteen germplasms were highly resistant, sixty nine germplasms read resistant, while eight germplasms recorded to be moderately resistant. None were found immune or susceptible.
