Assessment of stability performance in scented rice genotypes under transplanted condition of south-eastern plain zone of Rajasthan

Abstract

An experiment was conducted during kharif 2007 to 2009 to assess the stability performance of seven genotypes of scented rice (Oryza sativa L.) for grain yield and its component characters. Genotypic and G x E interaction variances were found to be significant for all the characters studied. Both linear and non-linear components of G x E interaction were also found significant. Estimates of stability parameters as general mean (X), regression coefficient (bi) and deviation from regression (S2 di) showed that, genotype IET 19491 was found stable for grain yield and number of panicles/m2, Pusa basmati-1 was found stable for plant height (cm) and days to 50% maturity.
