Stability analysis for yield and quality attributes in tomato (Solanum lycopersicum L.)

Author(s): SV Savale and AI Patel
To study stability of total 45 genotypes of tomato (32 hybrids + 12 parents + 1 commercial check) under three diverse environments were evaluated in Randomized Block Design (RBD) with three replications. Environment included three locations viz., Navsari (E1), Surat (E2) and Hansot (E3) under the Navsari Agricultural University, Navsari (Gujarat) during late kharif 2014-15 to identify the most stable genotypes. The pooled analysis of variances indicated that genotypes x environment interactions were highly significant for fruit yield per plant (kg) and pericarp thickness (mm) and these characters were subjected to stability analysis. Linear as well as non- linear component of G x E interactions were found to be significant for these characters indicating that response of genotypes varied in different environments. In general, all the genotypes did not show any uniform stability and linear pattern for all the traits. In present experiment, the parent viz., AVTO-4 and the hybrids AVTO-6 x GT-2 had high mean value over population mean, closer to one regression coefficient (bi) and low and non-significant deviation from regression and was highly stable for yield per plant. These genotypes are likely to perform well in all the three environments.
