Evaluation of Indian Dillenia (dillenia Indica) Germplasm in Hilly Region

Zulfiqur Ali Firoz
Principal Scientific Officer
Hill Tracts Agricultural Research Station, Ramgarh, Khagrachari

Abstract/ Executive Summary:

Five Indian dillenia germplasm were evaluated at the Hill Tracts Agricultural Research Station, Ramgarh during the year 2013-14. There was a lot of variability in respect to plant height, number of branch, spread of plant, fruit size, single fruit weight and percent edible portion. The tallest highest plant (24.25 m) was obtained from DI Ram-005 but the shortest plant (12.10 m) was in DI Ram-002. Maximum base girth (205.00 cm) was found from DI Ram-003, while minimum (56.00 cm) in DI Ram-001. The highest number of primary branches and highest canopy spread also found in DI Ram-003. The line DI Ram-03 produced the highest number of fruits (610/plant) followed by DI Ram-005 (516/plant), while DI Ram-004 produced the lowest fruits (145/plant). The heavier fruit (523.6 g) was produced by the line DI Ram-005, while the lighter (323.0 g) was in DI Ram-001. Maximum fruit yield (270.18 kg/plant) recorded from the line DI Ram-005 followed by DI Ram-003 (212.89 kg) and minimum (50.08 kg) in DI Ram-004.

Keywords: Indian dillenia, Dillenia indica, Growth parameters, Yield and quality, Edible portion

Location: Hill Tracts Agricultural Research Station, Ramgarh, Khagrachari

Start Date: 00-09-2012

End Date: 00-09-2014

Program Area: Variety and Species

Non-commodity: Performance

Objectives:

To study the performance of Indian dillenia germplasm at Ramgarh, Khagrachari
To evaluate, characterized and documented the Indian dillenia germplasm for improvement
To select superior Indian dillenia germplam in respect to yield and fruit quality for developed as varieties.

Methodology:

Five Indian dillenia germplasm (DI Ram-001 to DI Ram-005) were selected from different locations of Ramgarh, Khagrachari Hill District through personal communication and evaluated at Hill Tracts Agricultural Research Station, Ramgarh, Khagrachari during 2012-2014. Each of the plants was fertilized with cowdung 10 kg, Urea 500 g, TSP 500 g and MoP 500 g. The plants were fertilized twice in a year first in June-July, second in October-November. Fully mature fruits were harvested from the plant during September 2012 and 2013. Data on plant height (m), base girth of the plant (cm), number of main branches/plant, plant spread (m) and number of fruits/plant, fruit size (cm), weight of single fruits (g), and edible portion (%) were recorded from each plant as well as randomly selected 5 fruits from each plant.
