Abstract/ Executive Summary:

An experiment was performed at the Fruit Research Farm, Horticulture Research Centre, Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur during July, 2018 to July, 2019 to observe the performance of BARI developed jackfruit varieties viz. BARI Kanthal-1 (harvested during mid-May to June); BARI Kanthal-2 (harvested during January to March) and BARI Kanthal-3 (harvested during September to June). Saplings of jackfruit varieties were planted in June, 2018. Total number of grafted saplings was 36. Spacing was 5 X 4.5 m. Pit size was 1m x 1m x1m. The experiment was laid out in Randomized Complete Block Design (RCBD). Initial plant height on August 30, 2018 of BARI Kanthal-1, BARI Kanthl-2 and BARI Kanthal-3 was recorded 1.03 m, 0.40 m and 0.44 m, respectively and at July, 2019 plant height of BARI Kanthal-1, BARI Kanthl-2 and BARI Kanthal-3 was recorded 1.76 m, 1.78 m and 0.90 m, respectively. At the same time, base girth increased from 3.57 cm in August, 2018 to 8.92 cm in July, 2019 in the case of BARI Kanthal-1; 2.07 cm in August, 2018 to 9.47 cm in July, 2019 in case of BARI Kanthal-2 and 1.97 cm in August, 2018 to 9.78 cm in July, 2019 in the case of BARI Kanthal-3. Number of branches and number of leaves increased simultaneously. Only male inflorescences were observed in BARI Kanthal-1.

End Date: 00-07-2019

Program Area: Variety and Species

Commodity: Jackfruit

Objectives:

To observe the performance of BARI developed jackfruit varieties viz.

Methodology:

The experiment was carried out at the Fruit Research Farm of the Horticulture Research Centre under Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur during July, 2018 to July, 2019. Saplings of three jackfruit varieties were planted in July, 2018. Characteristics of three jackfruit varieties were described below-

BARI Kanthal-1: A regular bearing high yielding jackfruit variety which is harvested during Mid May to June; The average weight of a fruit is 9.5 Kg, fruit shape is oval and edible portion is 55%, fruit pulp is light yellow having pleasant flavor, juicy, medium soft and TSS (22^o Brix).

BARI Kanthal-2: An off-season regular bearing jackfruit variety which is harvested during the month of January to April. The average weight of a fruit is 6.95 Kg, fruit shape is oval and edible portion is 60%, fruit pulp is light yellow having pleasant flavor, juicy, medium soft and TSS (21^o Brix).

BARI Kanthal-3: A year round regular bearing jackfruit variety which is harvested during the month of September to June. Average weight of fruits is 5.43 kg, ß- Carotene- 35.06 mg/g and pulp is deep yellow and very sweet, TSS - 23.6^o Brix , edible portion -52.5%.

Prior to planting saplings of jackfruit the land was ploughed with power tiller and kept open for few days. Drainage system was developed. Pit was prepared and initially 20 Kg cow dung, 400 g TSP, 200 g MoP and 50 g gypsum were incorporated with the upper soil of pit. Total number of grafted saplings was 36. Spacing was 5 X 4.5 m. Pit size was 1m x 1m x1m. The experiment was laid out in a Randomized Complete Block Design (RCBD). Data on plant height, base girth, number of branches and flowering were recorded, analyzed statistically and the mean separation was done following DMRT.

Achievement/Findings:

BARI developed three jackfruit varieties viz., BARI Kanthal-1, BARI Kanthl-2 and BARI Kanthal-3 showed the sharp increase in plant height accounting from 69.0 to 345.0% and base girth 150% to 396%. It is the first year experiment. The experiment will be continued to observe the performance of jackfruit varieties at Joydebpur condition.
