Abstract/ Executive Summary:

Ten jackfruit germplasm viz., AH Joy-032 (3), AH Joy-039 (2), AH Joy-076 (2), AH Joy-078, AH Joy-099, AH Joy-115, AH Joy-202, AH Joy-203, AH Joy-215 and AH Joy-218 were evaluated to identify the superior ones at the Fruit Research Farm of HRC, BARI, Gazipur during 2019-20. A wide range of diversity was manifested in the tree characters, number of fruits per plant, fruit characters and pulp characters of jackfruit. Maximum plant height was recorded to be 7.35 m in AH Joy-203 and minimum plant height in AH Joy-115 (3.95 m). Base girth ranged from 58 cm in AH Joy-039 (2) to 120 cm in AH Joy-215. Trunk height varied from 0.88 m to 2.20 m. The number of fruits ranged from 7 to 50. Individual fruit weight ranged from 2.70 to 12.50 kg. Fruit length varied from 22.0 to 54.0 cm while diameter varied from 15.0 to 26.0 cm. Maximum and minimum bulb weights were recorded to be 5.98 in AH Joy-218 and 1.30 kg in AH Joy-039 (2), respectively. The number of bulbs per fruit varied from 52 in AH Joy-099 to 266 in AH Joy-218. Maximum and minimum edible portions were manifested to be 56.3 and 50.0 % in AH Joy-215 and AH Joy-039 (2), respectively. TSS content was varied from 17.0 to 27.0 ^o Brix. Considering a number of fruit per plant, fruit weight, edible portion, TSS content and pulp quality, germplasm AH Joy-202, AH Joy-218, AH Joy-215, AH Joy-115 and AH Joy-078 were found auspicious.

Keywords: Evaluation, Jackfruit, Germplasm

Location: Fruit Research Farm of Horticulture Research Centre, BARI, Joydebpur, Gazipur, Bangladesh

Start Date: 00-00-2019

End Date: 00-00-2020

Program Area: Variety and Species

Commodity: Jackfruit

Objectives:

To evaluate the performance at Joydebpur condition.

Methodology:

Collected jackfruit germplasm were planted at the Fruit Research Farm of HRC, BARI, Gazipur in 2008 for ex-situ evaluation. Planting distance was maintained as 5 m x 5 m. Design was nil. Tree and fruit characteristics of jackfruit germplasm were evaluated as per descriptor of jackfruit published by the International Plant Genetic Resources Institute (IPGRI, 2000). Data on number of fruits per plant and fruit characteristics were recorded during the harvesting period of 2020.

Achievement/Findings:

With respect to the number of fruit per plant, fruit weight, edible portion, TSS content and pulp quality, the germplasm AH Joy-202, AH Joy-218, AH Joy-215, AH Joy-115 and AH Joy-078 were found auspicious. The experiment will be continued for further evaluation. Among this superior germplasm, bulb of AH Joy-202 is sweet and firm which could be used for both table purpose and processing. Germplasm AH Joy-218 is free from latex when it is peeled. Its pulp is medium soft and very sweet. These two germplasm might be proposed as variety.
