The present study was carried out to identify pearl millet hybrids and populations suitable for general cultivation for enhancing pearl millet productivity levels in arid region of Rajasthan. The study included a set of 14 released genotypes consisting each seven hybrids and populations of pearl millet [Pennisetum glaucum (L) R. Br. emend. stuntz]. These genotypes were evaluated from 2006 to 2010 at ARS, Bikaner. Stability behaviour for days to 50 % flowering, days to maturity, plant height/plant (cm), effective tillers per plant, ear length per plant (cm), dry fodder yield per plant (gm), grain yield per plant (gm) and test weight (gm) was worked out. Analysis of variance showed that genotype x environment interaction was significant for all the characters. Among the components of G x E interaction i.e., G x E (linear) and pooled deviation, the variance due to pooled deviation alone registered significance for most of the characters. It indicated that the performance of genotypes is unpredictable over environments due to preponderance of non-linear component for the characters used in the study. It was concluded that the hybrids were more adaptive than the populations for yield and yield components. Among the 14 genotypes studied, hybrids RHB 121 and HHB 67-2 and population Pusa 266 were found stable for grain yield with high mean, regression coefficient (bi) around unity and deviation from regression coefficient (S2di) nearer to zero.
