Summary

Twenty genotypes of chilli were tested under four different environments for two years for their stability in performance for different traits. To assess the stability of different genotypes, the models given by Finaly and Wilkinson (3) and Eberhart and Russell (2) were used. The second order interactions were important for all the characters, while first order interactions in a few cases. The linear component of genotype-environmental interaction was significant for almost all the characters. The high mean yields were given by S-l18, S-l14 and S-138. S-138 had relatively better adaptability. S-l18, S-l14 and Long Red 70-4-4 were specifically adapted to high yielding environments, while NP-46 A was consistently a poor performer. The genotype S-14 for plant height and S-147 for plant spread showed wider adaptability and high stability. The genotypes S-l14 and Shahkot Chillies were highly stable for fruit length, while 70-2-1 for fruit diameter.
