Genetical studies on eight hybrids involving four induced mutants of local aromatic cultivars were made to gain information on recombination breeding and heterosis breeding. The hybrids IET-14142 x Pusa Basmati I for plant height, IET-14142 x Basmati-370 for panicles number, test weight and dry matter production, IET-13541 x Pusa Basmati I for primary branches per panicle, IET-13541 x Basmati-370 for spikelet number per plant, grain number per plant, dry matter production and grain yield per plant, 21-6-1 x Basmati-370 for spikelet number plant and 21-6-1 x Pusa Basmati-I for grain number plant, IET-14143 x Basmati 370 for grain length and IET-14143 x Basmati-370 for test weight and grain number plant would be effective for recombination breeding. The hybrid IET-14143 x Basmati-370 for panicle weight and spikelet number plant, IET-14142 x Pusa Basmati I for dry matter production plant, IET-13541 x Pusa Basmati I for panicle weight and secondary branches per plant, 21-6-1 x Basmati-370 for secondary branches per plant and grain yield per plant, 21-6-1 x Basmati 370 for dry matter production per plant would be promising for heterosis breeding. Although, the future breeding programme always should be based on their estimates in particular environment.
