Multi-location trials for growth parameters such as plant height (cm), primary branches per plant, days for first flower and days for maturity in horsegram [(Macrotyloma uniflorum (Lam.)Verdc] mutants are important for evaluation of genotype by environment interaction and identification of superior genotypes in the final selection cycles.The objective of this study was to evaluate stability and adaptability of growth parameters of horsegram mutants.Multilocation trails of horsegram mutants were conducted at different localities of five districts such as 1.Pokhari (Tal-Ashti, Dist-Beed), Chinchpur, Tal-Paranda, Dist-Osmanabad), 3. Hulgewadi (Tal-Karmala, Dist-Solapur), 4. Kuldharan (Tal-Karjat, Dist-Ahmednagar) and Pimpalwadi, (Tal-Kankavali, Dist-Sindhudurg).The stability of growth parameters in M 4 , M 5 and M 6 generations was investigated.Almost all mutants like early dwarf, early semi dwarf, late and high yielding showed stability in all generations at five localities in five districts of Maharashtra.
