The primary objective of the current research was to evaluate the available chickpea germplasms by screening method against root knot nematode M. incognita. | 2020 9 11 1636-1643 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 9 Number 11 2020 Journal homepage http Original Research Article https Screening of Chickpea Germplasms against Meloidogyne incognita Sulkshana Borah Aparajita Borah and Bornali Mahanta Department of Nematology Assam Agricultural University Jorhat Assam India Corresponding author ABSTRACT A pot experiment was carried out in the net house of Department of Nematology during the rabi season of 2016-17 to know the reaction of different germplasms of chickpea on Meloidogyne incognita. Twenty germplasms viz. JG-315 CSG-515 JG-16 JAKI-9218 RSG 991 GNG- 1958 GG-2 JG-14 Vijay IPCK 02-29 L550 Vishwas BG- 372 GNG- Keywords 1581 BG-256 GNG-469 Annegiri 1 Vishal HC-3 RSG-888 were obtain from the Director IIPR Kanpur. Five germplasms viz. JG62 ICCV10 JG 11 DCP and ICC313 M. incognita were obtained from Department of Agricultural Biotechnology Assam Agricultural Chickpea University Jorhat. Chickpea germplasm Avarodhi was taken as susceptible check. Ten Germplasam etc. days after germination each seedling were inoculated with 500 freshly hatched second stage juveniles of Meloidogyne incognita. Each treatment was replicated five times in Article Info CRD design. After forty five days of inoculation the root-knot index for each germplasms Accepted was determined on the basis of root-knot index 1-5 scale given by Sasser et al. 1984 . It 12 October 2020 was observed that among twenty five germplasms VIJAY and ICC-313 were found to be Available Online moderately resistant JG-315 CSJ-515 JG-16 RSG-991 JG-14 GNG-1581 BG256 10 November 2020 GNG-469 VISHAL HC-3 RSG-888 JG-62 ICCV-10 and DCP were found to be susceptible whereas remaining were recorded to be highly susceptible reaction towards M. incognita. It can be concluded that the moderately resistance varieties VIJAY and ICC- 313 can be used in the
