Evaluation of per se performance of parental lines and their hybrids for growth, yield and quality attributes in tomato (Solanum lycopersicum L)

Abstract

The present work entitled “Evaluation of per se performance of parental lines and their hybrids for growth, yield and quality attributes in Tomato (Solanum lycopersicum L).” was conducted at the Department of Vegetable Science, Chandra Shekhar Azad University of Agriculture Technology Kanpur during rabi 2022-23 and 2023-24. The experiment was laid out in randomized block design (RBD). Seven lines viz. EC-163605, EC-549819, Pusa Sheetal, Azad T-6, Kashi Anupam, KS-08767, KS-241 and three tester viz. Kashi Amul, Kashi Adarsh, And Kashi Amrit were grown in Rabi 2022 and mated into line × tester mating design and further the 21 F1s were grown in Rabi 2023. The result of the study revealed that among the lines EC-163605 performed better in case of number of leaves per plant (28.25, 47.33, 79.53, 114.10 at 30, 60, 90 and 120 DAT respectively), stem diameter (0.68, 1.02, 1.45, 1.92 cm at 30, 60, 90 and 120 DAT respectively), days of first flowering (21.50 DAT), days of 50% flowering (33.52 DAT), number of flower per cluster(5.42), fruit diameter (3.70 cm) and highest yield per ha(653.13kg). Among the tester Kashi Amul performed better in case of highest plant height(30.90, 63.55, 95.00, 120.20 cm at 30, 60, 90 and 120 DAT respectively), number of leaves per plant (27.50, 44.75, 80.85, 112.50 leaves at 30, 60, 90 and 120 DAT respectively), stem diameter(0.67, 0.97, 1.32, 1.85 cm at 30, 60, 90 and 120 DAT respectively), Days of first flowering, days of 50% flowering (34.76DAT), number of flower per cluster(5.35), fruit weight (75.00 gm), highest yield per ha(650.65kg), Highest TSS content(4.20 o Brix), and maximum Vit.C content(18.00). Among their hybrids EC-163605 × Kashi Amul perform better in case of plant height height (37.37, 72.51, 116.00, 137.07 cm at 30, 60, 90 and 120 DAT respectively), stem diameter diameter (0.70, 1.00, 1.41, 1.87 75 cm at 30, 60, 90 and 120 DAT respectively), days of first flowering (22.17 DAT), days of 50% flowering (35.00 DAT), number of flower per cluster (5.45), fruit diameter(4.90 cm), fruit weight (80.82 gm), Highest TSS (5.04oBrix), and maximum Vit. C content (21.93).
