Field experiments were carried out to evaluate sixteen varieties of tomato (Solanum lycopersicum Mill.) for their stability at three locations in Kashmir valley during kharif 2011 and 2012 i.e. six environments. Significant differences were observed among all the varieties for eight quantitative characters The pooled analysis of variance for stability of varieties for the quantitative traits over six environments revealed significant differences among the genotypes and environments for all the traits studied. The interaction component genotype × environment was also significant for all the traits. The varieties stable for yield and most of the traits were Arka Meghali, Shalimar-II, Roma and Arka Vikas. This implied that these varieties contributed less to the genotypic x environment interaction. Therefore, the varieties Arka Meghali, Shalimar-II, Roma and Arka Vikas could be used as breeding stock that could be incorporated in crosses with the objectives of improving the above mentioned traits.
