Abstract

                                A study was conducted during the period of June 2015 to January 2017 at college orchard of Tamil Nadu Agricultural University, Coimbatore with an objective to evaluate tomato (Solanum lycopersicum L.) genotypes suitable for polyhouse condition. Fifty one genotypes received from diverse agro climatic regions were used for evaluation of twenty characters in a randomized block design with two replications. The genotypes were assessed for plant height, days to first flowering, number of flowers per truss, number of fruits per cluster, number of fruits per plant, fruit setting percentage, number of harvest, individual fruit weight and yield per plant. The analysis of variance showed that there existed significant differences among the genotypes with all character tested. Among the genotypes, plant height ranged from 84.0 (IIVR EC 620464) to 476.0 cm (NBPGR HYD EC 165700). Early flowering was recorded in IIVR PB Kaghri (26.88 days). Number of flowers per truss ranged from 4.00 (Punjab Gourav) to 8.65 (IIHR 2042). The highest number of fruits per cluster was recorded in IIHR 2042 (7.61). Number of fruits per plant ranged between 5.00 in Punjab Gourav and 48.50 in NBPGR HYD IC 249514.The individual fruit weight ranged from 3.50 to 125.50 g in NBPGR HYD IC 249514 and in Pant Polyhouse Hybrid Tomato1 respectively. Yield per plant ranged from 0.20 kg (NBPGR HYD EC 145057) to 3.63 kg (IIVR EC 521038). From the study it was concluded that the tomato genotypes NBPGR HYD EC 165700 (476.0 cm) IIVR EC 521038 (3.63 kg) and IIHR 2042 (2.36 kg) could be most promising in terms of growth and yield under poly house condition.
