Abstract/ Executive Summary:

A study on the fruit characteristics, yield contributing characters and yield of five promising lotkon genotypes was carried out at the fruit Research Farm and Laboratory of Citrus Research Station, Bangladesh Agricultural Research Institute, Jaintiapur, Sylhet, during fruiting season of 2013. Five promising lines of lotkon viz., BS-Jai 001, BS-Jai 002, BS-Jai 003, BS-Jai 004 and BS-Jai 005 were included in the study. A wide variation was observed among the genotypes in respect of different characteristics under the present study. Per cent edible portion and total soluble solids (TSS%) were the highest in BS-Jai 001 (47.2% and 13.6%, respectively) while the lowest edible portion in BS-Jai 002 (36.7%) and the lowest TSS in BS-Jai 003 (12.4%). Heaviest (15.2 g) fruits with length and diameter of 3.4 cm and 3.4 cm was recorded from the genotype BS-Jai 003 whereas the lightest (8.6 g) with length and diameter of 2.2 cm and 2.7 cm was noted in BS-Jai 004. The highest number of fruits per plant (6000) as well as highest yield per plant (55.4 kg/plant) and per hectare (56.8 t/ha) were produced from the genotype BS-jai 005. BS-Jai 001 found superior in respect of fruit attractiveness, color, juicyness, flesh texture and eating quality.

Location: The orchard of Citrus Research Station, Bangladesh Agricultural Research Institute, Jaintiapur, Sylhet

Start Date: 00-07-2012

End Date: 00-07-2013

Program Area: Crop-Soil-Water Management

Commodity: Latkan

Objectives:

To study on the fruit characteristics, yield contributing characters and yield of five promising lotkon genotypes.

Methodology:

The study was conducted at the orchard of Citrus Research Station, Bangladesh Agricultural Research Institute, Jaintiapur, Sylhet during the period from July 2012 to July 2013. Five lotkon genotypes viz., BS-Jai 001, BS-Jai 002, BS-Jai 003, BS-Jai 004 and BS-Jai 005 were included in the study. The plants were healthy, about 25 years of age and received similar cultural treatments and bear fruits regularly. At the beginning of the study, the plants were rejuvenated by pruning of dead and diseased branches, freed them from parasitic plants, algae and lichen. The trunks of the trees were painted with Bordeaux paste to avoid fungal infection. The plants were fertilized with 30 kg cow dung, 1 kg urea, 1 kg TSP, 750 g MoP, 200 g gypsum, 50 g Zinc sulphate and 20 g boric acid in two equal splits; one in the month of May and another after rainy season in the month of October (FRG 2012). The plants were sprayed with Cypermethrin (Cymcare 10 EC @ 1ml/L of water) to control chapper beetle whereas tilt was sprayed @ 0.5 ml/l for controlling powdery mildew disease. Three hand weeding were done throughout the rainy season to avoid loses of soil nutrients by weed and also to destroy the harbor of insect pests. Data were recorded on yield contributing characters, yield and fruit characteristics. Data were analyzed by MSTAT-C computer programme and DMRT was performed for interpretation of results.

Achievement/Findings:

Considering the overall quantitative and qualitative characteristics along with yield of the fruits of all the studied genotypes, BS-Jai 001 and BS-Jai 005 were found to be superior to other genotypes in respect of fruit weight, number of fruits per plant, weight of fruits per plant, fruit TSS (%), fruit size and yield per hectare. These genotypes deserve a place in any lotkon varietal trial for selecting superior varieties.
