Abstract

Out of 15 varieties tested, none was recorded as resistant. However, Precilla and Pink dream were recorded as moderately resistant having gall index range of 2–3 and 3–3, respectively. Rest were classified as susceptible. Pathogenicity of root-knot nematode was studied at 0, 10, 100, 1,000 and 10,000 J2 of Meloidogyne incognita/kg soil under net house condition. The reduction in plant growth parameters was recorded at all the initial inoculum level, however the pathogenic level of root-knot nematode in Gladiolus was noticed at and above 1,000 J2 inoculum level. At the population density (1000 J2/plant) there were 24.6, 25.1, 22.3, 8.2, 20.2 and 25.7% reduction in shoot height, shoot dry weight, spike length, root length, corm diameter and corm dry weight, respectively over un inoculated check.
