Abstract/ Executive Summary:

The experiment was conducted at the experimental field of Olericulture Division, Horticulture Research Centre, Bangladesh Agricultural Research Institute, Gazipur during the winter season of 2013-14 to evaluate SVATNet tomato lines. There was significant variation among the lines in respect of different characters studied. Considering the growth pattern, two lines viz. STM001, STM002have been selected as semi-indeterminate, rest of the lines were determinate type. A wide range of variation in number of fruits per plant was observed which varied from 28.33 to 47.0, while the average fruit weight also varied from 57.33 to 97.00g. Fruit yield per plant varied significantly and it ranged from 2.10kg/plant to 3.59kg/plant. There was significant variation in fruit yield per hectare, highest fruit yield was obtained from STM006(94.95 t/ha) and followed by STM008(91.79t/ha) and minimum fruit yield was found in BARI tomato 15. On the basis of yield and yield contributing characters, virus infestation, five lines viz STM006, STM008, STM009, STM004 and STM001 were selected for further evaluation.

End Date: 00-00-2014

Program Area: Variety and Species

Commodity: Tomato

Objectives:

To evaluate the performance of the collected (SAARC countries) tomato lines with a view to develop new variety(s) with desirable traits.

Methodology:

The experiment was conducted at the experimental field of Olericulture Division, HRC, BARI during winter season of 2013-2014. Ten tomato lines were collected from SAARC countries. The seeds of above mentioned lines were sown in the seedbed on November 2, 2013. Thirty days old seedlings were transplanted in the main plot. The experiment was laid out RCB design with three replications having plot size of 4.8X1 sq m providing a spacing of 60x40 cm. The crop was fertilized with cowdung 10 ton, urea 550kg, TSP 450kg and MoP 250kg per ha, respectively. Half of the quantity of cowdung, entire TSP and half of the MoP were applied during land preparation. The remaining half of the cow dung was applied during pit preparation. The rest of MoP and entire urea 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 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, TSS(%), number of seeds per fruit, shelf life and percent virus infestation were recorded. The collected data on aforementioned parameters was statistically analyzed (Gomez and Gomez, 1983).
