Abstract/ Executive Summary:

A pot experiment was carried out in the grill house of the Department of Seed Science and Technology, Bangladesh Agricultural University (BAU), Mymensingh during the period of mid December 2014 to mid April 2015. The experiment conducted with five treatments (five tomato genotypes) and employed in Completely Randomized Design (CRD) with four replications. Of the five genotypes two were obtained Japan (Pasta and Mimi) and the rest three from Bangladesh Agricultural Research Institute (BARI). Genetic variations appeared for morphological and phenological characters and yield attributes in the five tomato genotypes. Taller plants with higher number of branches were observed in the Japanese genotype (Mimi) while number of days required to initiate flower and fruit initiation and fruit maturity were shorter in BARI tomato 12 and BARI tomato 14. Flower and fruit productions plant^-1 was higher in BARI released tomato cultivars, therefore, the tomato yield was also higher in those cultivars.

Start Date: 00-12-2014

End Date: 00-04-2015

Program Area: Variety and Species

Commodity: Tomato

Objectives:

To determine the Variation in Morphological Attributes and Yield of Tomato Cultivars

Methodology:

Experimental site and time: The experiment was conducted at the grill of the Department of Seed Science and Technology, Bangladesh Agricultural University (BAU), Mymensingh, during the period from mid December 2014 to mid April 2015. Experimental materials: Five tomato genotypes Japanese tomato (Pasta), Japanese tomato (Mimi), BARI tomato 2, BARI tomato 12 and BARI tomato 14 used as experimental materials. The seed of Japanese tomato genotypes were collected from Japan (Kaneko Seed Co. Ltd.) and BARI tomato variety from Horticulture division of Bangladesh Agricultural Research Institute (BARI), Gazipur. Treatments: Five tomato genotypes considered as five different treatments and four replications were used in the experiment. Preparation of pot: Pots were used for the experiment (20 inch) and total numbers of pots were 20. The selected pots were filled with soil. Then the soil mixed with organic manure and fertilizer ( urea 2.09 g, MoP 0.99 g, cowdung 400 g and compost 50 g pot^-1). Statistical analysis: Yield and yield contributing data were collected and analyzed statically following the analysis of variance (ANOVA) technique and the mean differences were adjudged by Duncan’s Multiple Range test (DMRT) using the statistical computer package program, MSTAT-C (Gomez and Gomez, 1984).

Achievement/Findings:

The genotype BARI tomato14 produced the highest number of flowerclusters plant^-1 and fruit clusters^-1. Japanese tomato Mimi a n d BARI tomato 12 showed higher plant height and in a total maximum number of primary branches plant^{- 1} was found in Japanese tomato Pasta and BARI tomato 14 produced the highest number of fruits and fruit yield. BARI tomato 14 showed the best yield performance in compare to other genotypes.
