Stability of reproductive characters such as pods per plant, pod length (cm), seeds per pod, 1000 seed weight (g) and seed yield per plant (g) in horsegram [(Macrotyloma uniflorum (Lam.)Verdc] mutants was evaluated by conducting multilocation trials at different localities.Trails are important for evaluation of genotype by environment interaction and identification of superior genotypes in the final selection cycles.Multilocation trials are often used to analyse the adaptability of genotypes in different environments and to find for each environment the genotype that is best adapted.The objective of this study was to evaluate stability and adaptability of reproductive characters of horsegram mutants.Multilocation trails of horsegram mutants were conducted at different localities of five districts of Maharashtra 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 reproductive 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.
