The yield stability of eight faba bean (Vicia faba L.) varieties was studied in Great Britain and France across nine environments. The varieties were categorized into a small seeded group (Maris Bead, Blaze, Dacre, Kristall, an2048d Herra) and a large seeded group (Felix, Minica, and Wierboon C.B.). The two groups were different in plant height, pod profile, and earliness. All varieties were analyzed for their stability. Simple correlation between stability parameters for yield and those for yield components and other characters were determined. Significant variety x environment interactions were detected for seed yield and other characters. The variation in the linear and non-linear components of the V x E interactions indicated significant differences between the characters involved. No significant relationship between seed yield and the various stability parameters was found, but between variance (v), b (regression coefficient) and S2 d (deviation from the regression) of these parameters highly significant relationships were found. However, significant positive correlations between stability parameters for seed yield and some parameters of 1000-seed weight were detected. A high stability for yield components such as 1000-seed weight and maturity should be considered when breeding for yield stability in faba b
