Abstract/ Executive Summary:

A field experiment was conducted at Bangladesh Institute of Nuclear Agriculture (BINA) Farm, Mymensingh from October 2007 to March 2008 with a view to evaluating the physical and chemical properties, nutrient content, and infestation rate of tomato fruit borer of different mutants and varieties. The treatments consisted of six mutants viz; TM-13, TM-105, TM-110, TM-133, TM-152, TM-155, and two varieties BARI tomato-7 and BINA tomato-5. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The infestation of tomato fruit borer varied significantly among the mutants/varieties. The number of fruit borer was 2.15-5.98. The following growth parameters, yield contributing characters, and chemical composition of the tomato mutants/varieties were studied which were 1.03-1.40 cm stem diameter, 14.9-19.5 cm² leaf area, 10.08-20.10 mm^-2 leaf hair, 36.7-52.0 number of leaves plant^-1, 13.86-24.67 number of fruits plant^-1, 24.1- 60.2 g single fruit weight, 3.69-4.0 pH, 17.1 -25.2 mg 100 g^-1 vitamin-C, 0.307-0.408% TA, 2.34-2.75% reducing sugar, 0.93-1.20% non-reducing sugar. Tomato fruit borer infestation was negatively correlated with leaf hair and a number of fruit plant^-1 but positively correlated with stem diameter, leaf area, leaf number plant^-1 single fruit weight, non-reducing sugar, pH and titrable acidity. It is concluded that TM-133 and TM-13 mutants were the best among the tested verities respectively.

Location: Bangladesh Institute of Nuclear Agriculture (BINA) farm, Mymensingh, Bangladesh.

Start Date: 00-10-2007

End Date: 00-03-2008

Program Area: Pest Management

Commodity: Borer, Tomato

Objectives:

To identify the plant morphological characters and chemical characteristics influencing the infestation rate of tomato fruit borer and to analyze the nutrient status of different tomato mutants/varieties.

Methodology:

The experiment was conducted at the Bangladesh Institute of Nuclear Agriculture (BINA) farm, Mymensingh, Bangladesh. Eight tomato genotypes were used in the study. Among them, two varieties (BINA tomato-5 and BARI tomato-7) developed and released by the Bangladesh Institute of Nuclear Agriculture (BINA) and Bangladesh Agricultural Research Institute (BARI) respectively and six trans mutants (TM-13, TM-105, TM-110, TM- 133, TM- 152 and TM- 155) were developed by Bangladesh Institute of Nuclear Agriculture (BINA). The experiment was laid out in a Randomized Complete Block Design (RCBD) with 3 replications. The plot size used was 4 m × 3 m. Prior to planting, experimental plots were ploughed and cross-ploughed three times by power tiller followed by laddering to obtain desirable tilth. All the stubbles, crop residues, and uprooted weeds were collected and removed from the plots before planting. Data were recorded on an individual plant basis from 10 randomly selected plants in each plot. Sampling was done at one stage of tomato plants. The pest was examined carefully in the tomato plants from canopy to bottom the observation was made very carefully on the stem and both sides of the leaf. Other physical parameters (Plant height, Leaf area, Stem diameter, Leaf hair density, number of leaves plant^-1, Number of fruits plant^-1 and Single fruit weight), chemical and biochemical parameters measured include Vitamin C content, pH, Titrable acidity, Reducing and non-reducing sugar contents were recorded. All chemical and physical parameter analyses were carried out at the Department of Agricultural Chemistry, and Central Laboratory, Department of Crop Botany, and Department of Biochemistry, Bangladesh Agricultural University, Mymensingh, Bangladesh. The data was analyzed statistically by F-test [9]. Analysis of variance was done with the help of the computer package M-STAT [10]. The mean comparisons of the treatments were separated by using DMRT (Duncan's Multiple Range Test) at a 5% level of significance.

Achievement/Findings:

Considering all the genotypes and varieties, TM- 133 produce the highest vitamin-C content, pH value, titrable acidity, reducing sugar content, non-reducing sugar content. Besides Fruit borer population was also found lowest in number. From the study, it could be concluded that TM- 133 and TM-13 mutants were the best among the test entries irrespective of physical parameters, insect infestation rate, chemical composition, and other nutrient contents of tomato fruits. Further studies at different locations of Bangladesh should be undertaken to confer the results of our studies before the final conclusion and releasing the genotypes as varieties.
