Abstract/ Executive Summary:

An experiment with nine pummelo genotypes was conducted at the hill valley of Agricultural Research Station, Raikhali, Rangamati Hill District for the evaluation of pummelo lines in the hilly region during 2012-13. Maximum number of fruits per tree (18) was observed in CG Rai-009 followed by CG Rai-004 (15) and minimum in CG Rai-011 (03). The highest weight of individual fruit (1.31 kg) was found in CG Rai-004 followed by CG Rai-002 (1.21 kg) and the lowest (1.00 kg) in CG Rai-009. The highest TSS (8.5%) was observed in CG Rai-004 and CG Rai-005, whereas the lowest (5.5%) was recorded in CG Rai-010. Maximum edible portion (65%) were found in CG Rai-002 followed by CG Rai-004 (57%) and the minimum (40%) in CG Rai-009. Maximum number of segments (15) was recorded in CG Rai-004 and CG Rai-005, while it was noted minimum (12) in CG Rai-011. The oragnoleptic taste was performed very good for CG Rai-004 and CG Rai-005 compared to the poor taste in CG Rai-010 and CG Rai-011. Bitterness was absent in CG Rai-001, CG Rai-002, CG Rai-004 and CG Rai-005.

Keywords: Pummelo, Adaptability, Evaluation, Fruit characteristics

Location: Agricultural Research Station, Raikhali, Rangamati

Start Date: 01-06-2012

End Date: 01-09-2013

Program Area: Variety and Species

Commodity: Pummelo

Objectives:

To find out the superior pummelo genotypes in the Chittagong Hill Tracts.

Methodology:

The experiment was conducted at the existing five years old pummelo orchard at hill valley of Agricultural Research Station, Raikhali, Rangamati Hill Distric during the period of 2012-13. The genotypes were collected from different parts of the Chittagong Hill Tracts. Nine genotypes viz., CG Rai-001, CG Rai-002, CG Rai-004, CG Rai-005, CG Rai-006, CG Rai-007, CG Rai-009, CG Rai-010 and CG Rai-011 were included in this study. It was maintained at 5 × 5 m spacing. Manures and fertilizers were applied @ 15 kg cowdung, 500 gm urea, 400 gm TSP, 450 gm MoP per tree. The fertilizers were applied in three installments in a year. First installment was applied during February, second in May and the last in October. Intercultural operations like weeding, irrigation, pruning etc were done as and when necessary. Data on yield and yield contributing characters were taken duly.

Total Budget (Tk.) : 25000/-

Achievement/Findings:

Based on the individual fruit weight, TSS%, edible portion and organoleptic taste it might be concluded that the genotypes CG Rai-004 and CG Rai-005 are superior and the next year investigation of this experiment is needed.
