Stability for quality and physiological traits of tomato under high temperature conditions over dates of sowing

Abstract: An investigation was carried out with twenty five genotypes to study phenotypic stability based on Eberhart and Russel model over three dates of sowing viz., February, March and April sowings in Vegetable Research Station, Rajendranagar, Hyderabad, Telangana state. Mean sum of squares due to environments was significant for all the traits which indicated the strong influence of environment on genotypes. The genotypes were significantly differed for lycopene content which showed the wide variability for these traits over seasons. Significant mean sum of squares due to genotype x environment interactions were noticed for ascorbic acid and remained non-significant for rest of the traits. Among eight traits studied, Arka Alok andAVTO-9803 for ascorbic acid and PKM-1 for lycopene are recommended for general cultivation. The results revealed that one genotype for number of locules per fruit, Seven genotypes for total soluble solids (TSS), ten genotypes for lycopene, one genotype for stomatal diffusive resistance (SDR), eight genotypes each for relative water content (RWC) and chlorophyll content (CC) are recommended for unfavourable environments and one genotype for number of locules, eleven genotypes for TSS, seven genotypes for lycopene, two genotypes for SDR, five genotypes for RWC and ten genotypes for CC are recommended for favourable environments. Based on favorability of environments, February sowing is best for SDR, RWC and CC characters, March sowing is best for ascorbic acid and lycopene characters and April sowing is best for number of locules per fruit and TSS.
