Abstract: The present study was carried out at the Research and Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during kharif 2007, rabi 2007-08 and kharif 2008. The experimental material consisted of parents, F₁, and F₂ of the each crosses (i.e. Abhaya x Swarna and Jhitpiti x Swarna, respectively), the crosses between F₁’s (Abhaya x Swarna // Jhitpiti x Swarna) and F₂ recombinant population of this cross. The experimental material consisted of Abhaya and Jhitpiti gall midge resistant varieties along with one ergonomically superior but gall midge susceptible variety i.e., Swarna. The screening test revealed that Abhaya and Jhitpiti varieties were resistant against gall midge, whereas Swarna was susceptible. Inheritance study reported the presence of single dominant gene for gall midge resistance in Abhaya and Jhitpiti. Allelic studies revealed the ratio 15 R: 1 S indicated that the gene governing resistance in Abhaya and Jhitpiti were independent resistant genes
