Abstract

                                Five barnyardmillet genotypes viz., Sadai kudiraivali, Pullu kudiraivali, CO (KV) 2, VL 29 and VL 172 were evaluated over five different environments to study the stability parameters viz., regression coefficient (bi) and mean square deviations (S 2 d i ). Variances due to genotype, environment, genotype x environment, environment (linear) and pooled deviation were significant for days to 50 per cent flowering, days to maturity, plant height and grain yield. Based on the stability analysis, the genotype CO (KV) 2 was found to be stable across five different environments for days to maturity, plant height and grain yield. Hence, it may be recommended for the commercial cultivation in these five environments.

Key words : Barnyardmillet, Stability, Regression coefficient, Grain yield
