    A field investigation entitled “Evaluation of cherry tomatoes (Solanum lycopersicum L. var. cerasiforme) for yield and quality under shade net” was carried out at experimental farm, Horticultural College and Research Institute, Dr. Y.S.R. Horticultural University, Anantharajupet, Y.S.R. (Dist.), Andhra Pradesh during the early kharif-2013. The experiment consists of eleven cherry tomato genotypes viz., IIHR-2871(T1), IIHR-2872(T2), IIHR-2873(T3), IIHR-2751(T4), IIHR-2753(T5), IIHR-2876(T6), Laila(T7), Roja(T8), Ruhi(T9), Sheeja(T10) and AFA 602(T11) replicated thrice in a Randomized Block Design under 50 per cent shade net. The results on growth parameters revealed that maximum plant height at 90 days after transplanting in Roja (313.26 cm) followed by Laila (312.20 cm). Sheeja (3.20) followed by IIHR-2876 (3.00) produced significantly highest number of primary branches plant-1. The genotype AFA 602 (28.40) took significantly minimum number of days for first flower initiation followed by Ruhi and Roja, which took 29.88 and 30.40 days respectively. Similarly the genotype, AFA 602 (70 days) took the shortest period from transplanting to first fruit harvest followed by Roja (71days). IIHR-2872 took least number of days (39.66) to 50 per cent plants to flowering and said to be an early genotype followed by Roja (41.33). Highest number of flowers cluste-1 and number of fruits cluster-1 was noticed in the genotype Sheeja (10.70 and 9.46) followed by Ruhi and Laila (9.80, 7.80 and 9.60, 7.20 respectively). Maximum number of fruiting clusters plant-1 at harvest was recorded by Sheeja (31.46) followed by IIHR-2872 (29.80), while the genotype IIHR-2751 (14.60) recorded the minimum. Fruit set percentage was maximum in Sheeja (88.8) which is at par with Roja, Laila, AFA 602 and Ruhi with a fruit set values of 88.8, 86.53, 82.80 and 81.10 per cent respectively. The longest fruit was recorded in genotype IIHR-2872 (4.12 cm) followed by Sheeja (4.06 cm) and Laila (4.05 cm). The genotype IIHR-2873 (4.17cm) followed by IIHR-2873 (3.67cm) produced significantly highest fruit width. Fruit shape index was found maximum in Sheeja (2.00) followed by Laila (1.91) and Roja (1.58). Significantly highest fruit volume was recorded in IIHR2872 (20.33 cc) followed by IIHR-2751 (18.26 cc). The highest mean fruit yield plant-1, fruit yield plot-1 and fruit yield hectare-1 was recorded in AFA 602 followed by Sheeja (3.70 kg, 40.68 kg, 53.70 tonnes and 3.64 kg, 38.68 kg, 50.96 tonnes respectively). With respect to quality parameters TSS was maximum in Roja (8.46 0 B) followed by Laila (8.10 0B), titrable acidity was highest in IIHR-2873 (0.48 %) followed by Roja (0.45 %), highest ascorbic acid content was recorded in IIHR2753 (27.55 mg 100g-1) followed by Ruhi (27.38 mg 100g-1), lycopene content was maximum in genotype Roja (8.570 mg 100g-1) followed by Laila (6.85 mg 100g-1). The genotype Roja (4.81%) followed by IIHR-2871 (3.42%) recorded significantly maximum reducing sugars content. IIHR-2753 (1.68 %) followed by Sheeja (1.54) showed maximum values for non-reducing sugars. The cherry tomato genotypes AFA 602 and Sheeja outperformed other genotypes in terms of yield when grown during early kharif under 50 per cent green shade net. The reason might be the genetic potentiality of these genotypes to perform well under favourable micro climate. The genotypes AFA 602, Sheeja and Roja were found to be early maturing. With respect to quality parameters, the genotype Roja and Laila were found promising as they recorded higher values of total soluble solids, lycopene content and reducing sugars which can be better exploited in the processing industry.
