Abstract/ Executive Summary:

Yield and quality performances of three jackfruit genotypes were studied at the Agricultural Research Station, Bangladesh Agricultural Research Institute, Pahartali, Chittagong during 2013-2014. Age, growth, maturity period, yield potential and also qualitative characteristics were compared among them. Based on overall performance with respect to bearing potential, maturity period, fruit and bulb characters, the genotypes AHPah^-1 have been found promising for table purpose followed by AHPah^-2 and AHPah^-3. Minimum days (117) to 1^st harvest were observed in AHPah^-1. The number of fruits per plant was exceedingly higher (73) in AHPah^-1 whereas minimum number (41) was found in AHPah^-2. Maximum weight (8.40 kg) per fruit was observed in AHPah^-2 and minimum was in AHPah^-1(3.40 kg). The highest single fruit length (37.25cm) was found in AHPah^-2 and breadth (27.00cm) was produced by AHPah^-3. Maximum number of bulbs (116) was produced in AHPah^-1, whereas minimum (63.00) was in AHPah^-3. Maximum weight of bulbs per fruit (4.24 kg) was produced in AHPah^-2. Individual bulb weight was higher (54.42g) in AHPah ^-2 whereas, the lowest (16.71) was in AHPah^-1. Edible portion was higher (69.27%) in AHPah^-1 whereas, the lowest (53.43%) was in AHPah^-3. The TSS was the highest (21.00%) in AHPah^-1. The highest bulb length and breadth was found in AHPah^-3. Highest seeds weight (639g) was produced in AHPah^-2. Individual seed weight (8.19 g) was higher in AHPah^-2. Therefore, the genotypes can be included in the variety development program after comparing with the already BARI released jackfruit variety.

Program Area: Variety and Species

Commodity: Jackfruit

Objectives:

The present study was to identify jackfruit genotypes for higher yield and quality.

Methodology:

The experiment was conducted at the Agricultural Research Station, Bangladesh Agricultural Research Institute, Pahartali, Chittagong during 2013-2014. Three jackfruits genotypes, namely AHPah^-1, AHPah^-2 and AHPah^-3 were included in the study. The experiment was laid out in a randomized complete block design with five replications. The trees were 12-15 years old and were fertilized twice in a year in October and May as per schedule described by Mandal et al. (2011) @ 7500-1200-1250-800-500 g of cowdung, urea, TSP, MoP and zypsum per plant, respectively. Diazinon 60 EC @ 2 ml along with Ridomil MZ- 75 @ 2.5 ml per litre of water was sprayed with the help of a power sprayer before the flower initiation to control soft rot disease and fruit borer insect. Weeding, irrigation and other interculture operations were done as per recommendation by Mandal et al. ( 2011). Girth of the trunk was measured at a height of 15 cm from ground level and tree volume was calculated following Castle (1983) with some modifications, such as π/6 x height x (2r)² where, 2r=(East - West + North – South canopy spread)/2. Data on plant age, base girth, plant height, canopy (North-south and east-west spread), flowering, fruits number and weight per plant, fruit size, single fruit weight, fruit shape and colour, bulb number and weight per fruit, bulb size, TSS, edible portion and seeds number and weight per fruit, seed colour, size and organoleptic characteristics were recorded . Data were analyzed statistically and the means were separated by Least Significant Difference (LSD) following MSTATC software.

Achievement/Findings:

Considering the above results, it can be concluded that the genotype AHPah ^-1 bears the maximum fruits and the other characteristics such as fruit colour, bulb colour, firmness, juciness, taste, texture were better than other genotypes. Therefore, the germplasm can be included in the variety development program after comparing with the already BARI released jackfruit variety.
