Abstract:
A field study was conducted during kharif 2018-19 crop season at department of Plant Pathology and experimental farm, College of Agriculture, Sawmi Keshwanand Rajasthan Agriculture University, Bikaner, Rajasthan to test the resistance of 31 germplasm/varieties against Sclerotium rolfsii under field condition. Pure culture of pathogen was mixed in soil before one week of sowing. Each germplasm/varieties were sown in second week of July in three rows of 5 m row length keeping 10 cm plant to plant distance. The disease incidence was recorded using 0-9 rating scale. Among thirty one varieties/germplasm two two genotypes viz.GR-13 and GP-15 were highly resistant, nine genotypes/varieties viz., GR-3, GR-5, GR-6, GR-7, GR-8, GR-10, RGC-1066, RGC-1055 and GP-17 were categorized as resistant. Another twelve genotypes/varieties viz., GR-1, GR-2, GR-4, RGC-1033, GP-12, GP-13, GP-14, GP-16, GP-18 GP-19, GR-11 and GR-12 were moderately resistant, five genotypes/varieties were moderately susceptible viz., GR-9, GR-14, RGC- 1017, RGC-1031 and RGC-1003, two genotypes/varieties RGC-936 and RGC-986 were susceptible, and remaining one variety RGC-197 was highly susceptible.
