Abstract
Stability parameters for grain yield were worked out for five erect leaf genotypes of fingermillett (ragi) viz., IE 252, IE 503, IE 629, IE 798 and TNAU 5 and four normal high yielding varieteies, PR 202, Co.7, Co.13 and Paiyur 1. Significant differences were observed for genotype. environment and genotypes x environment interaction. TNAU 5 and PR 202 recorded above average response for grain yield, low regression coefficient and low mean square deviation from regression indicating their adaptability to unfavourable environments. All other varieties except IE 252 were found to be adaptable for favourable environment. In general, mean square deviation from regression was very low in all the genotypes studied. There was a decline in grain yield of these genotypes when planted at higher plant density levels.
