Studies on resistance in some pearl millet hybrids against Meloidogyne graminicola

Abstract

Study was conducted to find out sources of resistance against Meloidogyne graminicola in some pearl millet hybrids, their parental lines (A-Line and R-lines) and Maintainer lines (B lines). In order to find exact reaction screening of germplasm lines was done for two years i.e. 2017 and 2018. Hybrids and germplasm lines were classified highly susceptible to highly resistance adopting 1-5 scales of root-knot index. Out of 36 germplasm, 8 were moderately resistant, 25 resistant and 3 susceptible (HHB 272, 94555 A and 843-22A) to Meloidogyne graminicola infection. All the tested R-lines were found resistant against root-knot nematode infection.
