Abstract/ Executive Summary:

Burmese grape (Baccaurea sapida Muell. Arg.) is an underutilized fruit crop grown mainly backyard plantation as well as forest plant. It is native of Sumatra, Borneo and Java. In Bangladesh, it is commonly known as Lotkon which is primarily cultivated as a home-garden tree. It is a mild acidic fruit and mainly used as fresh fruit. It flowers during the months of summer and fruits are harvested in rainy season. Bearing habit of Burmese grape is adventitious or cauliflory in nature. The fruit is oval to round in shape and turns yellow or yellowish brown in ripen condition. The type of fruit is berry and edible portion is leathery rind aril. Burmese grape is propagated mainly by seeds but grafted saplings are popular. An attempt has been made in the present study to evaluate the physico-chemical properties of different Burmese grape genotypes in FTIP-BAU-GPC. The investigation was carried out with twelve germplasms. The data collected from the experiment revealed that the germplasms varied among themselves regarding different physico-chemical attributes of fruits in fully ripe condition. The maturity for fruit harvesting is least in Accession No. 9 (78.33 days) followed by Accession No. 8 (80.66 days) and it is maximum (90.33 days) for the Accession No. 7. For most of the desirable attributes, the Accession No. 11 showed better response like maximum length (3.383 cm), diameter (3.513 cm), weight (19.93 gm), juice content (74.10 ml/10 fruit) and lowest acidity (1.996%).

Program Area: Variety and Species

Commodity: Grape

Objectives:

1. An attempt has been made in the present study to evaluate the physical and bio-chemical properties of different Burmese grape genotypes of FTIP-BAU-GPC as well as an attempt was made to know the maturity period of different Burmese grape Accessions.

Methodology:

The investigation was carried out with twelve Accession of Burmese grape germplasms (indicated as Acc 1-12 in tables) grown in the FTIP-BAU-GPC. All the plants aged between ten to fifteen years and were well grown, free from pests and diseases. While selecting the germplasm it is kept in mind that the collar diameter and the canopy of the selected Accessions were similar. After fruit set, the required fruit bunches were tagged on all sides to obtain uniform result. The fruits were harvested and subjected for studies on physico-chemical changes during ripen stage. Three fruit bunches were harvested randomly from each selected plant and ten fruits of each bunch were taken to the laboratory, Department of Horticulture, Bangladesh Agricultural University (BAU) to observe the fruit length (cm), fruit diameter (cm), fruit weight (g), peel weight (g), peel thickness (mm) in average and 10 seed weight (g), juice content (ml/10 fruits). The total soluble solids (TSS) of the fruits measured with hand refractometer. Total sugar content and titratable acidity were determined with standard of A.O.A.C. To determine the maturity of Burmese grape 10 inflorescences each from four direction of the each Accession were tagged and days taken for maturity was recorded by the simple computation methods by counting the days after fruit set of each inflorescences upto the maturity. The observations were analyzed in simple Randomized Block Design as suggested by Gomez and Gomez

Achievement/Findings:

The data collected from the experiment revealed that the germplasms varied among themselves regarding different physico-chemical attributes of fruits in fully ripe condition. The maturity for fruit harvesting is least in Accession No. 9 (78.33 days) followed by Accession No. 8 (80.66 days) and it is maximum (90.33 days) for the Accession No. 7. For most of the desirable attributes, the Accession No. 11 showed better response like maximum length (3.383 cm), diameter (3.513 cm), weight (19.93 gm), juice content (74.10 ml/10 fruit) and lowest acidity (1.996%).
