Abstract/ Executive Summary:

Different quantitative and qualitative characteristics of three superior mango germplasm namely MI Joy-002, MI Joy-004, and MI Joy-005 grown at the Fruit Research Farm of Horticulture Research Centre, BARI, Joydebpur, Gazipur were studied during 2013-14. A wide range of variation was recorded for plant height. MI Joy-005 exhibited maximum plant height (4.68 m) closely followed by MI Joy-002 (4.35 m). Full bloom took place from early to late February among the germplasm studied. All the germplasm had the mid season fruits harvested from 1st week of June to 3rd week of June) . Number of fruits per tree varied from 102 in MI Joy-004 to 242 in MI Joy-005. Maximum fruit weight was recorded from MI Joy-004 (260.3 g) and mimimum fruit weight was recorded from MI Joy -002 (178.5 g). The largest fruit was obtained from MI Joy-004 with 9.19 cm length, 7.30 cm breadth and 6.88 cm thickness while the smallest from MI Joy-002 (7.40 cm length, 6.34 cm breadth and 5.95 cm thickness). The highest TSS was noted in MI Joy-004 (20%) while the lowest was in MI Joy-005 (18.07%).

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Variety and Species

Commodity: Mango

Objectives:

To obtain information on the performance of chance seedlings in respect of adaptability, yielding ability and quality of mango.

Methodology:

The experiment was conducted at the Fruit Research Farm of Horticulture Research Centre, BARI, Gazipur during 2013-14. Six superior germplasms of mango namely MI Joy-001, MI Joy-002, MI Joy-003, MI Joy-004, MI Joy-005 and MI Joy-006 were included in this study. But among the germplasm, in case of MI Joy-001 and MI Joy-003 fruit-setting was not occurred. Fruits of MI Joy-006 were not harvested in the reporting time as its harvesting time was last week of July. For this reason, MI Joy-006 was not reported, only floral characteristics were reported. The experiment was laid out in a Randomized complete block design (RCBD) with three replications. One year old veneer grafts were planted in the field on July 2006 at a spacing of 8m × 8 m. A single tree of each germplasm constituted the unit of replication. The trees were fertilized with 25 kg rotten cowdung, 750 g urea, 500 g TSP, 250 g MoP, 250 g gypsum and 15 g zinc sulphate in two split doses of manure and fertilizers (recommended dose for 8-10 years old plant) at the beginning and the end of the rainy season with light irrigation. Intercultural operations such as weeding and ploughing were done in the month of September, December, March, May and July. Regular irrigations with 15 days and 30 days interval were applied at blooming stage and fruiting stage, respectively. Ripcord @ 1 ml and Tilt 250 EC@ 0.5 ml per litre of water was applied twice, one before flower opening stage and another one at pea stage to control mango hopper and anthracnose. Necessary actions were taken against other pest and diseases as and when needed. Data on tree growth as well as quantitative characteristics were recorded as per ‘Description for Mango’ published by IBPGR in 1989. Tree volume was calculated by using the formula of Castle (1983). Tree Volume= 1/6 π × plant height × (2r)2, where 2r = (East-West spread + North-South spread)/2.

Achievement/Findings:

Maximum fruit weight was recorded in MI Joy-004 (260 g) and minimum was recorded in MI Joy-002 (178 g) which was statistically similar to that of MI Joy- 005 (199 g). Total Soluble Solids was noted highest in MI Joy-004 (20%), which was statistically at par to that of MI Joy-002 (19.67%), while the lowest was found in MI Joy-005 (18.07%). The germplasm MI Joy- 002 and MI Joy- 005 exhibited deep yellow color pulp and MI Joy- 004 resulted in pulp yellow color. Considering overall growth condition, yield and fruit quality almost all the germplasm were appeared satisfactory.
