Abstract:
Field studies were carried out to evaluate the reactions of pigeonpea, mungbean and chickpea against root-knot nematode (Meloidogyne incognita) during Kharif and Rabi, 2018- 2020. A total of 28 genotypes of pigeonpea, 20 genotypes of mungbean and 29 genotypes of chickpea were screened in sick plot area of Nematology. The initial nematode population was recorded above pathogenic level in both the seasons. The observations on number of galls/plant and number of eggmasses/plant were recorded after 45 days of sowing. The different genotypes were categorized from highly resistant to susceptible based on number of galls and gall index. Out of 28 genotypes of pigeonpea, four genotypes showed resistant reaction and 15 were moderately resistant. In case of chickpea, out of 29 genotypes; three genotypes showed resistant reaction and seven were found moderately resistant while out of 20 genotypes of mungbean, four genotypes showed moderately resistant reaction against RKN. The remaining genotypes were either categorized as susceptible or highly susceptible.
