Abstract/ Executive Summary:

A regional yield trial (RYT) of two selected cherry tomato lines of AVRDC and one advance cherry tomato line with check BARI Tomato-11 was conducted at the experimental field of Olericulture Division, Horticulture Research Centre (HRC) and at five RARSs of Bangladesh Agricultural Research Institute (BARI), Gazipur during the winter season of the year of 2017-18 to assess the yield potentiality, pest and disease reaction and adaptability. The fruit number per plant varied from 290 to 322. The highest fruit yield per hector obtained from SL0068 (71.03), while second highest yield (61.85 tons) was exhibited by the control. But the yield difference between SL0067 and control is statistically identical. The magnitude of virus infestation showed ranged from 0.41-2.0 %.

Keywords: Cherry tomato, High yielding, Performance, Regional yield trial

Location: Olericulture Division of HRC, BARI, Joydebpur, Gazipur Bangladesh

Start Date: 00-00-2017

End Date: 00-00-2018

Program Area: Variety and Species

Commodity: Tomato

Objectives:

1. To evaluate the performance of the WVC supplied selected potential cherry tomato lines in different ago-ecological zones and; 2. To develop high yielding cherry tomato variety for Bangladesh.

Methodology:

The experiment was carried out at the experimental field of Olericulture Division of HRC along with more five RARSs of BARI during winter season of 2017-‘18.The selected (selection was made in the year of 2012-2013 onward) WVC supplied tomato lines viz.: SL0067 and SL0068 were considered for this study, while BARI Tomato-11 was used as check. The seeds of above mentioned lines and variety were sown in the on 3^rd week of October, 2017. Thirty days old seedlings were transplanted in the main plot on 3^rd week of November, 2017. The crop was fertilized with cow dung 10 ton, N-253kg (urea- 550kg), P- 90kg (TSP-450kg), K-125 (MoP-250kg), S- 21kg (Gypsum-116kg), Zn-4.9kg (Zinc Sulphate-14kg) and B-2kg (12kg) per ha, respectively. Half of the quantity of cow dung, entire P and half of the K, entire zinc and boron were applied during land preparation. The remaining half of the cow dung was applied during pit preparation. The rest of K and entire N were applied at three equal installments at 15, 30 and 45 days after transplanting. Plant protection, irrigation and other intercultural operations were done as and when necessary. Data on yield and yield attributing parameters with qualitative traits were recorded from 20 inner plants of each plot escaping border plants following AVRDC guide line as below: days to first and 50% flowering, plant height at last harvest, days to maturity, number of fruit /plant, average fruit weight, fruit length and diameter, fruit yield /plant, yield/ plot, yield /ha, number of seeds per fruit, shelf life and percent of virus infestation (at 45 DAS, 60 DAS and 75 DAS) were recorded. The experiment was laid out in the randomized complete block design (RCBD) with 3 replications. Three treatment combinations were randomly allotted in each block. The size of a unit plot was 4.8m × 1m, and the plant spacing was 60cmx40cm. Each unit plot contained 2 rows of plants (24 plants/ plot). The recorded quantitative data were analyzed statistically by F-test to find out the variation due to different treatments .Analysis of variance (ANOVA) and treatment means were compared by Least Significant Difference (LSD) test following R Software 3.1.2 (Anon., 2015).

Achievement/Findings:

Considering the horticultural traits, pest and diseases reactions and yield potentials in unit area, SL0068 may be suggested to release as cherry tomato variety and may also be recommended for growing at different agro-ecological zones of Bangladesh.
