Genotype X Environment Interaction of Some Tomato Hybrids under Kashmir Conditions

Ms. Ummiyah H Masoodi

To evaluate seventeen hybrids of tomato (Solanum lycopersicum Mill.) field experiments were carried out 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 hybrids for eight quantitative characters. As per the model of stability analysis by Eberhart and Russel (1966), the pooled analysis of variance for stability of hybrids 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 hybrids stable for yield and most of the traits were TO-687, Indam-531, Rambo, PS-255, Maharaja and Swaraj-1516. This implied that these hybrids contributed less to the genotypic x environment interaction. Therefore, the hybrids TO-687, Indam-531, Rambo, PS-255, Maharaja and Swaraj-1516 could be recommended to the farmers of Kashmir for cultivation.

As per the quality parameters analysis, Shalimar Tomato Hybrid-1 (3.187 mg/100g) among all hybrids had the highest lycopene content, Arth-3 (6.230 mg/100g) had the highest total carotenoids, the highest Vitamin C content was found in PS-255 (30.913 mg/100g). Samrat-1861 had the highest dry matter (4.100 %), Shalimar Tomato Hybrid-1 had the highest mean for TSS (6.507 0B), PS-255 (2.730) had the highest juice/pulp ratio and the highest acidity (0.510 %) as well, specific gravity was highest in Arth-3 (0.977). The hybrids TO-687, Indam-531 and Rambo showed suitability for fresh market, PS-255, Maharaja and Swaraj-1516 for both processing as well as fresh market purposes.
