Abstract/ Executive Summary:

A study on collection and evaluation of tomato germplasm was conducted at the experimental field of Olericulture Division of Horticulture Research Centre (HRC), Bangladesh Agricultural Research Institute (BARI), Gazipur during the winter season of 2017-18 with 14 collected tomato lines for selecting superior lines and increasing of seed. All the lines showed different performance in every parameter studied. The line SL0419 contributed the highest per plant yield (3.10 kg) with good shelf life (16 days) having semi-determinate nature. The tomato lines SL0420, SL0421, SL0422 and SL0507 showed more than 2.00 kg yield per plant. There were seven tomato entries- SL0419, SL0420, SL0421, SL0422, SL0424, SL0504 and SL0507 considered as suitable for further study.

Keywords: Performance, Tomato, Germplasm

Start Date: 00-00-2017

End Date: 00-00-2018

Program Area: Variety and Species

Commodity: Tomato

Objectives:

To evaluate the performance of the tomato germplasm for selecting superior lines and increasing seed.

Methodology:

The experiment was carried out at the experimental field of Olericulture Division of HRC, BARI during winter season of 2017-18. There were 14 tomato germplasm collected from different sources (exotic and local) namely- SL0419, SL0420, SL0421, SL0422, SL0423, SL0424, SL0501 (CN), SL0502 (CN), SL0503 (CN), SL0504, SL0505, SL0507, SL0508 and SL0509 included for this study. The seeds of above mentioned entries were sown in the seedbed on October 20, 2017. Thirty days old seedlings were transplanted in the main plot on November 19, 2017. The experiment was laid out in non-replicated design having plot size of 4.8X1 m providing plant spacing of 60x40 cm. 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. Irrigation, pruning, mulching weeding and other intercultural operations were done as and when necessary. Plant protection, irrigation and other intercultural operations were done as and when necessary. Data on days to first flowering, days to 50% flowering, plant height at last harvest, days required for first harvest, fruit length, diameter, number of fruit per plant, individual fruit weight, fruit yield per plant, NTSS, number of seeds per fruit, shelf life and percent virus infestation were recorded. Other qualitative characters as per descriptor also recorded. The collected data on aforementioned parameters was statistically analyzed (Zaman et al., 1982) as of Microsoft EXCEL program.

Achievement/Findings:

Considering the plant growth habit, flowering trends and other horticultural traits, the lines SL0419, SL0420, SL0421, SL0422, SL0424, SL0504 and SL0507 may be selected for put into preliminary yield trials in the next year. The line SL0419 treated as semi-determinate nature.
