Abstract/ Executive Summary:

Four germplasm of rose apple such as SJ Akb-001, SJ Akb-002, SJ Akb-003 and SJ Akb-004 were evaluated at the Regional Agricultural Research Station, Akbarpur, Moulvibazar during the year 2013-14. Fruit characters of six rose apple germplasm were varied remarkable. Among the germplasm maximum single fruit weight (17.50 g) was obtained from SJ Akb-001, followed by SJ Akb-004 (13.00 g) and minimum from SJ Akb-003 (10.90 g). The highest fruit length (4.10 cm) was found in SJ Akb-001, while the lowest (3.39 cm) in SJ Akb-004. The highest fruit breadth (3.25 cm) was found in SJ Akb-001, followed by SJ Akb-004 (3.23 cm), while the lowest (2.96 cm) in SJ Akb-002. Maximum and minimum skin thicknesses were observed in SJ Akb-001 (0.37 cm) and SJ Akb-002 (0.26 cm), respectively. Weight of seed ranged from 3.17 (SJ Akb-002) to 4.00 g (SJ Akb-004). The highest TSS (10.60%) was obtained from SJ Akb-001 and the lowest (6.50%) from SJ Akb-004. The line SJ Akb-001 was very good in taste and other germplasm produced fruits having good taste

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Variety and Species

Non-commodity: Performance

Objectives:

To study the performance of rose apple germplasm at Akbarpur, Moulvibazar
To evaluate, characterized and documented the rose apple germplasm for improvement
To select superior rose apple germplam in order to release as variety.

Methodology:

The experiment was conducted at Regional Agricultural Research Station, Akbarpur, Moulvibazar during the year of 2013-14. Four germplasm of rose apple viz. SJ Akb-001, SJ Akb-002, SJ Akb-003 and SJ Akb-004 were included in this study. The experiment was laid out in a single row plantation with three replications. The planting distance was 5 ×5 m. The plants were fertilized with cowdung (20 kg), urea (250 g), TSP (250 g), MoP (200 g) and gypsum (100 g) in two equal installments one at the onset and other at the end of rainy season. Mature fruits were harvested during May, 2014. Data on number of fruits/plant, single fruit weight (g), fruit length (cm), fruit breadth (cm), skin thickness (cm),seed weight (g), edible portion (%), TSS (%), yield/plant (kg), shape of fruit, organoleptic taste and insect-diseases reaction were recorded and the mean data were calculated. Fruit qualitative and quantitative parameters were recorded randomly selected 10 fruits from every harvest of each plant.
