Summary Genotype-environment interactions for green fodder yield in yellow sweet clover (Melilotus parviflora Desf.), by growing 10 genotypes in four different years, revealed that the genotypes interacted significantly with the environments and a large portion of these interactions was accounted for by the linear function of the environmental means. No association existed between the mean values and both the parameters of stability (b and S d 2 ). High yielding genotype HFYS 3 was found to be stable for favourable environments, whereas genotype HFYS 7 was more suitable for poor environmental conditions. Genotypes HFYS 8, 10 and 11 were found to be highly stable, whereas the genotypes HFYS 3, 7, 24, 25 and 44 were medium in their stability. Check variety FOS 1 and the genotype HFYS 43 were highly unstable. Prediction of the mean performance was made using two methods, one by using all the genotypes studied in a set of environments and the other by using only one stable genotype. It was possible to predict the mean performance of most of the genotypes within the limits of sampling error. Use of only one stable genotype for the purpose of prediction was found to be quite useful. The importance of studies on genotype-environment interactions in future breeding programme has also been discussed.
