Abstract/ Executive Summary:

Some sweet caranda germplasm at RARS, hathazari were evaluated to observe their field performances as well as their genetic variations. Wide genetic variations were observed among different physio-morphological parameters studied. The highest (40 cm) base girth was observed in CC Hat-001, CC Hat-002 and CC Hat-004, respectively. Maximum number of main branch (5) was found in CC Hat-003 followed by CC Hat-004 (4). CC Hat-001 was the tallest (2.90 m) plant whereas CC Hat-002 was the shortest (1.30 m). CC Hat-004 produced the highest (2.90 x 2.95 m) canopy in E-W and N-S direction, respectively among the genotypes. There were differences among yield and yield contributing parameters studied. Single fruit weight was the highest (9.20 gm) in CC Hat-002. This line also produced the longest (3.11cm) fruits whereas the shortest breadth fruit was observed in same line (2.01 cm). Qualitative parameters also showed differences among the genotypes studied. Edible portion was found higher in CC Hat-004 (85.11%) while that of the lowest in CC Hat-002 (84.56%). The TSS was higher in CC Hat-002 (12.00%) and lower in CC Hat-004 (11.17%).

Keywords: Sweet caranda, Evaluation, Fruit yield, Fruit quality

Location: Regional Agricultural Research Station, Hathazari, Chittagong

Start Date: 00-00-2010

End Date: 00-00-2011

Program Area: Variety and Species

Commodity: Sweet caranda

Objectives:

To study the performance of sweet caranda germplasm at Hathazari.
To evaluate, characterized and documented the sweet caranda germplasm.
To developed sweet caranda variety having higher yield and good quality.

Methodology:

Five sweet caranda germplasm viz. CC Hat-001, CC Hat-002, CC Hat-003, CC Hat-004 and CC Hat-005 were collected and planted at Regional Agricultural Research Station, Hathazari, Chittagong and evaluated during 2010 to 2011. The plants were planted during 2006 maintaining 3 x 3 m plant spacing in a single row. Each of the plants was fertilized with cow dung 20 kg, Urea 250g, TSP 250g and MP 250g in two installments at the beginning and the end of the rainy season. Intercultural operations were done as and when necessary. Fully mature fruits were harvested from the plant during August-September. Fully mature fruit were harvested from the plants and after ripening five fruits from each plant were randomly selected for evaluation. Data on plant height, base girth, spreading, branching density, number of primary branches, time of flowering, time of harvesting, harvest duration, number of fruits/plant, fruit weight (g), fruit length (cm), fruit breadth (cm), seed per fruit, seed weight (g), edible portion (%), TSS (%), yield/plant (kg), shape of fruit, fruit color at ripen, organoleptic taste and insect-diseases reaction were recorded and the mean data were calculated.

Budget: 15000/-

Total Budget (Tk.) : 15000/-

Achievement/Findings:

The vegetative growth of the sweet caranda germplasm were found excellent hence it was concluded that the climatic condition of Chittagong is suitable for sweet caranda cultivation. Among the studied germplasm the germplasm CC Hat-002 and CC Hat-004 exhibited superior performance in respect of number of fruits/plant, fruits weight, fruit size and yield. Both the germplasm also performed better in respect of TSS content of fruits, skin colour, flesh colour as well as taste, and might be selected for recommended as varieties.
