Abstract/ Executive Summary:

Some quality characteristics of fruits of seven jamun germplasm were studied at Agricultural Research Station, Raikhali, Rangamati during 2013-14. Studied quality characteristics of seven jamun germplasm exhibited a wide variation. The fruit flesh thickness varied from 4.28 to 7.47 mm. Maximum fruit flesh thickness (7.47 mm) was observed in SC Rai-004 followed by SC Rai-001 (6.50 mm) and minimum (4.28 mm) in SC Rai-002. The highest edible portion (85.92%) was recorded in SC Rai-004 followed by SC Rai-001 (80.12%) as against the lowest (71.82%) in SC Rai-002. Maximum TSS (14.80%) was noted in SC Rai-004 and SC Rai-006. Minimum TSS (12.70%) was noted in SC Rai-005. The organoleptic taste of SC Rai-004 and SC Rai-006 were very good while SC Rai-001, SC Rai-003 and SC Rai-005 were comparatively poor in taste. Fruits of all the genotypes were black in color, oblong in shape with flat fruit apex.

Start Date: 00-00-2012

End Date: 00-00-2014

Program Area: Variety and Species

Non-commodity: Performance

Objectives:

To study the quality characteristics of jamun germplasm under Chittagong Hill Tracts
To evaluate, characterized and documented the quality characteristics of jamun germplasm
To select superior jamun germplam on the basis of quality characteristics for release as variety.

Methodology:

The study was conducted at Agricultural Research Station, Raikhali, Rangamati Hill District during 2013-14 for the quality characteristics of jamun in hilly area. Seven grafted jamun germplasm viz., SC Rai-001, SC-Rai-002, SC-Rai-003, SC Rai-004, SC Rai-005, SC Rai-006 and SC Rai-007 were transplanted at 2009 in the minor fruits block of ARS, Raikhali, Rangamati. The study was laid out in a single row plantation with three replications maintaining 8 × 8 m plant spacing. The soil was fertilized with well decomposed cowdung @ 25 kg/plant, 230 g N, 185 g P₂O₅ and 240 g K₂O per plant per year. N P & K were applied in the form of urea, TSP and MoP, respectively in two equal installments in a year, the first during September-October and the second during April-May. Intercultural operations like irrigation, weeding etc. were done as per requirement. Data on quality characteristics viz. edible portion (%), TSS (%), shape of fruit, fruit color at ripen, flesh colour and organoleptic taste were recorded and the mean data were calculated. Parameters were recorded from randomly selected 10 fruits at each harvest.
