Abstract/ Executive Summary:

A study was conducted at the Hill Agricultural Research Station (HARS) in Khagrachari hill district with thirteen rose apple genotypes during January 2011 to May 2012. Fruit of different rose apple genotypes showed variation among themselves in various fruit characteristics under study. The genotype SJ Kha-143 produced the highest fruit weight (17.34 g) followed by SJ Kha-148 (16.24 g). Fruit length of different genotypes varied from 3.42cm (SJ Kha-144) to 2.8cm (SJ Kha-116), whereas fruit breadth ranged from 3.44cm (SJ Kha-143) to 2.8cm (SJ Kha-116). Seed weight varied from 4.58g (SJ Kha-148) to 2.26g (SJ Kha-116). Number of seeds/fruit were varied from 2.4 to 1.4. Colour of fruits at mature condition varied from greenish to yellow. Harvesting period was from April to May. TSS of rose apple genotypes varied from 13% (SJ Kha-138) to 9% (SJ Kha-144). Maximum percentage of edible portion (80.29%) was obtained from SJ Kha-144 which was closely followed by SJ Kha-137 (77.16%) and minimum in SJ Kha-126 (67.50%). Maximum yield/plant was obtained in SJ Kha-137 (5.31 kg) and minimum was obtained from SJ Kha-144 (2.17kg).

Location: Hill Agricultural Research Station, Khagrachari

Start Date: 00-01-2011

End Date: 00-05-2012

Program Area: Variety and Species

Commodity: Rose apple

Objectives:

To study the performance of rose apple germplasm at Khagrachari hill district.
To evaluate, characterized and documented the rose apple germplasm.
To developed rose apple variety having higher yield and good quality.

Methodology:

The experiment was conducted at the Hill Agricultural Research Station in Khagrachari hill district during January 2011 to May, 2012. The 13 rose apple genotypes, namely SJ Kha-102, SJ Kha-115, SJ Kha-116, SJ Kha-117, SJ Kha-126, SJ Kha-131, SJ Kha-134, SJ Kha-137, SJ Kha-138, SJ Kha-140, SJ Kha-141, SJ Kha-142, SJ Kha-143, SJ Kha-144, and SJ Kha-148 were collected and planted in the hill valley of HARS, Khagrachari. Seedling of rose apple were planted in 2006 at a spacing of 6 m X 6 m following single row planting system. One plant constituted a unit plot. Each of the plants was fertilized with cow dung 10 kg, Urea 500g, TSP 550g and MP 250g in two installments at the beginning and the end of the rainy season. Intercultural operations like weeding, spading for loosing of soil, irrigation during drought season etc. were done as and when necessary. Mature fruits were harvested during May, 2012. Data on plant height, base girth of the plant, number on main branches/plant, plant spread and fruit characteristics were recorded from each plant. Single fruit weight, fruit size, TSS (%) and edible portion were recorded randomly selected 10 fruits from every harvest of each plant.
