Abstract/ Executive Summary:

The study with four hybrids and BARI Hybrid Tomato 5 as a check variety was conducted at five locations of BARI which include Joydebpur, Ishwardi, Jamalpur, Potuakhali and Akberpur in the winter season of 2014-15. The response of test hybrids to marketable fruits per plant (MF/Pl), average fruit weight (AvFtwt), and marketable yield per hectare (MY/ha) when data of all the locations were combined. marketable fruits per plant varied from 30 (W11Hybrid 33) to 46 (WS11Hybrid 1) at combined data while it ranged from 20- 80 across the locations. The test hybrids WS11Hybrid1 had higher marketable fruits per plant (45.49) than the check variety (37.54) at combined data. average fruit weight was higher in three hybrids W11Hybrid 33, 35 and 37 (102.70- 111.92g) than the check variety (91.56g) at combined data. Except W11Hybrid 37 all the test hybrids produced higher and similar yield (97- 109 t/ha) than the check variety (92.27t/ha) at combined data. W11Hybrid 35 gave average higher yield (108.45 t/ha) at combined data. Three hybrids (Hybrid 1, 35 and 37) had lower virus incidence (0.0-5.7 %) than the check variety (7.2 %) of which Hybrid 1 may be considered as highly resistant (HR) (0.0 % incidence) while the rest resistant (R) (4.2-7.2 % incidence) under field condition. Considering average fruit weight, marketable fruits per plant, marketable yield per hectare and virus reaction two hybrids, hybrid 35 and 37 were found promising which can be processed for release as variety.

Location: Joydebpur, Ishwardi, Jamalpur, Potuakhali and Akberpur

Start Date: 00-00-2014

End Date: 00-00-2015

Program Area: Variety and Species

Commodity: Tomato

Objectives:

To select suitable hybrids with high yield, better quality and wide adaptability across the country.

Methodology:

The study consisted of four hybrids and BARI Hybrid Tomato 5 as a check. It was conducted at five locations of BARI which include Joydebpur, Ishwardi, Jamalpur, Potuakhali and Thakurgaon in the winter season of 2014-15. Age of transplanted seedlings varied from 25-36 days at different locations. The experiment was laid out in RCB design with three replications. The plant spacing maintained 60 cm between rows and 40 cm between the plants within the row in the bed. The land was fertilized with cow dung, N, P, K, S, Zn and B @ 5000, 253, 90, 125, 22, 5.4 and 2 kg/ha respectively. Half of the cow dung; entire quantity of P, S, Zn, B and 1/3rd of K were applied as basal dose during final land preparation. The remaining amount of cow dung was applied in pit as basal and K in two equal installments as split at 20 and 40 days after transplanting. The entire urea was applied in three equal installments as top dressing at 20, 40 and 60 days of transplanting. Intercultural operations were done as and when needed. Measured characters include days to 50% flowering, flower per cluster, fruit per cluster, duration of fruit harvest, marketable fruits per plant (MF/Pl), average fruit weight (AvFtwt) in gram, marketable yield per plant in kg, marketable yield per hectare (MY/Ha) in ton, total soluble solid in % (TSS), locule number in fruit, virus incidence (VI) and virus reaction. For convenience, the data of all locations for three characters which include MF/Pl, AvFtwt and MY/ha for interpretation were combined . Data was recorded from 10 randomly selected plants per genotype per replication.
