Abstract/ Executive Summary:

A study was conducted at Citrus Research Station (CRS), Jaintapur, Sylhet with two germplasm of dragon fruit viz., HU Joy-001 and HU Jai-002 during four consecutive years 2015-16, 2016-17, 2017-18 and 2018-19. Nnumber of side branches was found maximum (19) in HU Jai- 002 and minimum (15) in HU Jai-001. Flowering duration was recorded from 24 May to 28 May between the germplasm. The highest number of fruits was obtained from HU Joy-002 (21). HU Jai-002 produces the largest fruit (397g) with maximum (81.11%) edible portion.

Location: BARI headquarter, Gazipur and another one germplasm were collected locally and planted at research field of Citrus Research Station, Jaintapur, Sylhet, Bangladesh

Start Date: 00-00-2018

End Date: 00-00-2019

Program Area: Crop-Soil-Water Management

Commodity: Dragon fruit

Objectives:

To release white fleshed and more improved varieties of Dragon fruit.

Methodology:

One dragon fruit germplasm were supplied from BARI headquarter, Gazipur and another one germplasm were collected locally and planted at research field of Citrus Research Station, Jaintapur, Sylhet in January, 2012, with a distance of 3×3 m² spacing in concrete pole. Each plant was fertilized with 20 kg cow dung, 200 g urea, 250 g of TSP, 150 g of MOP, 50 g of gymsum, 20 gm Zinc sulphate and 10 of boric acid (Mandol et al., 2014). The plot was irrigated twice a month in dry period. Bavistin 50 wp was applied @ 2g/liter of water to prevent foot and stem rot. Data were recorded on spreading, side branches, and flowering and fruit characteristics.
