Morpho-physiological Evaluation of Three Promising Mutants of Tomato

Dr. Md. Tariqul Islam
Principal Scientific Officer and Head,
Crop Physiology Division, Bangladesh Institute of Nuclear Agriculture, BAU Campus, Mymensingh-2202, Bangladesh

Abstract/ Executive Summary:

The experiments were carried out with three advanced tomato mutants viz. TM-4, TM-5, TM-8 along with two check varieties, Binatomato-7 and Binatomato-11 at different locations during November 2017-March 2018. The locations were BINA farm, Mymensingh, Rangpur, Magura and Ishurdi and farmers’ field at Sutiakhali, Mymensingh, Rangpur and Magura. The experiments were laid out following a randomized complete block design with three replications. Data on morphological, yield and yield attributes were recorded at harvest from 10 randomly selected plants in each plot and fruit yield was taken from the whole plot and converted into kg/ha. The collected data were analyzed statistically. The variety, Binatomato-11 was the shortest one. On the other hand, the mutant TM-8 was the tallest. TM-5 produced the highest number of branches whilst Binatomato-11 the lowest. The mutant TM-5 produced the highest number of fruits plant^-1 with larger fruit size in most of locations. TM-8 showed the highest fruit yield at 2 locations out of 7 locations followed by TM-4. The two varieties, Binatomato-7 and Binatomato-11 showed poor yield performance as compared to other 3 mutants at all locations. The mutant TM-5 performed the best followed by TM-8 and TM-4.

Keywords: Tomato, Yield, Location

Location: BINA, Mymensingh

Start Date: 01-11-2017

End Date: 31-03-2018

Program Area: Variety and Species

Commodity: Tomato

Objectives:

To evaluate yield potential of tomato mutants at different locations of Bangladesh

Methodology:

The experiments were carried out with three advanced tomato mutants viz. TM-4, TM-5, TM-8 along with two check varieties, Binatomato-7 and Binatomato-11 at different locations during November 2017-March 2018. The locations were BINA farm, Mymensingh, Rangpur, Magura and Ishurdi and farmers’ field at Sutiakhali, Mymensingh, Rangpur and Magura. The experiments were laid out following a randomized complete block design with three replicates having a unit plot size of 4 m × 5 m. Row to row and plant to plant distances were 50 cm. Recommended doses of fertilizers were used and proper cultural practices were done as and when necessary. Data on morphological, yield and yield attributes were recorded at harvest from 10 randomly selected plants in each plot and fruit yield was taken from the whole plot and converted into kg/ha. The collected data were analyzed statistically.
