The data recorded on five qualitative traits were subjected to analysis of variance to test the significance of difference among the genotypes. Analysis of variance presented in Table 2, showed that the mean square due to genotypes were highly significant for all the traits. Mean performance of the various genotypes for the quality traits in tomato are presented in Table 3.

Total soluble solids (%)
Table 3: Mean performance of the various genotypes for the quality traits in tomato (Solanum lycopersicum L.).
Total soluble solid (%) ranged from 3.20% (2016/TODVAR-2) to 6.23% (2015/TODHYB-4) with the mean value of 4.46%. Top ranking genotypes as compared to mean are Kashi Aman (4.93%), Jawahar-99 (4.86%), Kashi Vishesh (4.80%), Sel.7 (4.73%), whereas the genotypes 2016/TODVAR-10 (3.93%), Kashi Hemanth (3.90%), VRT-01 and 2015/TODHYB-1 (3.80%) were showed significantly lower value. The results are in agreement with the findings of Neeraj et al. (2015
) and Pradeep Kumar et al., (2001).
Lycopene content (mg/100 g)
The lycopene content ranged from 6.80 mg/100 g (2016/TODVAR-12) to 18.50 mg/100 g (Kashi Aman) with the general mean of 12.13 mg/100 g. The genotypes namely 2015/TODHYB-1 (16.80 mg/100 g), VRT-19 (15.06 mg/100 g), TOLCV-28 (14.56 mg/100 g), VRT-13 (14.36 mg/100 g) and Kashi Anupam (13.60 mg/100 g), have exhibited significantly highest lycopene content as compared to general mean, whereas the genotypes viz
., 2016/TODVAR-5 (10.63 mg/100 g), Kashi Hemanth (10.23 mg/100 g), Kashi Amrit (9.36 mg/100 g), Kashi Chayan, Jawahar-99 (8.70 mg/100 g) and 2016/TODVAR-3 (7.90 mg/100 g) had lowest lycopene content as compared to general mean. The results are in agreement with the earlier findings of Gonalez-Cebrino et al., (2011).
Ascorbic acid content (mg/100 g)
The ascorbic acid content ranges from 18.73 mg/100 g (Marglobe) to 29.30 mg/100 g (Kashi Chayan) with the mean value of 22.91 mg/100 g. The genotypes Kashi Hemanth (26.26 mg/100 g), 2016/TODVAR-1 (25.63 mg/100 g), Jawahar-99 (24.86 mg/100 g), Sel.7 (24.73 mg/100 g) and TOLCCV-16 (23.93 mg/100 g) were showed significantly highest ascorbic acid as compared to general mean. The genotypes viz.
, Kashi Aman (19.30 mg/100 g), 2015/TODHYB-4 (19.30 mg/100 g), VRT-01(19.53 mg/100 g), Kashi Anupam (22.60 mg/100 g), 2016/TODVAR-12 (22.80 mg/100 g) had lowest ascorbic acid content. These results are in agreement with the earlier findings of George et al., (2004)
and Kaur et al., (2002).
Titrable acidity (%)
The highest and lowest titrable acidity was observed in Marglobe (0.46%) and Kashi Amrit (0.16%). The general mean for this trait was 0.28%. The genotypes namely, 2015/TODHYB-4 (0.37%), Kashi Hemanth (0.35%), TOLCV-28 (0.32%), 2016/TODVAR-11 (0.32%), Jawahar-99 (0.31%), were showed significantly highest titrable acidity as compared to general mean, whereas the genotypes viz
., VRT-13, Kashi Anupam (0.17%), VRT-19, 2016/TODVAR-3 (0.25%), 2015/TODHYB-1 (0.43%) were showed significantly lowest titrable acidity. The results are in agreement with the findings of Toor et al., (2006)
and Pradeep Kumar et al.
Juice to pulp ratio
The highest and lowest values for the trait juice to pulp ratio was recorded as 2016/TODVAR-5 (0.71) and Roma (0.27). The general mean for this trait was 0.50. The genotypes viz
., Kashi Vishesh (0.66), 2016/TODVAR-3 (0.65), 2015/TODHYB-1 (0.64), TOLCV-32 (0.59), 2016/TODVAR-12 (0.56) were showed significantly highest values for the trait as compared to general mean. The genotypes, TOLCV-16 (0.47), 2016/TODVAR-11 (0.46), Kashi Amrit (0.44), VRT-01 (0.41), Kashi Chayan (0.37), were showed significantly lowest value.
performance of tomato genotypes/varieties for all the quality traits revealed that Kashi Vishesh, Kashi chayan, Roma and Sel-7 were the best, hence these genotypes/varieties can be used as such in promotion of tomato production programme as elite germplasm lines/varieties or may be recommended for commercial cultivation after testing them over years and locations.
