Abstract/ Executive Summary:

The study was conducted at the experimental field of horticulture division, RARS, Rahmatpur, Barishal during the winter season of 2018-19 to evaluate the performance of the accession to get a good line to release a new high yielding variety. Wide variations in growth characteristics among the accession were found. The tallest plant was observed in accession number SD Rah-05 (13.20 m) which was followed by SD Rah-04 (13.10 m) and the smallest plant in BARI Amra-2 (8.50 m). The longest fruit length (6.87 cm) was obtained from BARI Amra-2 followed by accession number SD Rah-02 (6.76 cm). On the other hand, the shortest fruit length (6.20 cm) was recorded from the accession number SD Rah-05. In this trait the mean value was 6.55 cm. The longest fruit diameter (5.50 cm) was obtained from the accession number SD Rah-03 and smallest fruit diameter (5.10 cm) was recorded from the accession number SD Rah-01. The heaviest fruit was harvested from SD Rah-04 (92.00 g) and the lightest average fruit weight was obtained from SD Rah-05 (88.00 g). The height total number of fruit per plant was found in SD Rah-01 (692) followed by the accession SD Rah-03 (646) and the lowest one was SD Rah-025 (512). The yield of fruit per plant was varied significantly and ranged from 45.06 kg to 72.52 kg. The fruit of accession number SD Rah-01 produced the highest yield of 72.52 kg/plant followed by accession number SD Rah-03 (67.70 kg/plant). On the other hand, the lowest (45.06 kg) fruit yield was recorded in accession number SD Rah-05. In this trait, the mean value was 61.30 kg.

Start Date: 00-00-2018

End Date: 00-00-2019

Program Area: Crop-Soil-Water Management

Commodity: Wood apple

Objectives:

To evaluate the performance of the selected germplasm to get a good line to release a new high yielding variety.

Methodology:

The study was conducted at the experimental field of horticulture division, RARS, Rahmatpur, Barishal during the winter season of 2018-19. Five local accession and BARI Amra-2 was included in the study. The plant was fertilized twice in a year one before rainy season another after harvest for better growth and development. Weeding was performed after 6-8 days of each irrigation. Insecticide was sprayed twice at 7 days interval on the last week of February for controlling insect infestation. Data on base girth, plant height, north south and east-west spreading, plant growth, fruit length, fruit diameter, TSS (%) and yield per plant were recorded and analyzed statistically.

Achievement/Findings:

Wide variation in quantitative and qualitative growth characteristics among the golden apple accession indicates the ample scope of crop improvement through selection. Among five accessions, the yield of fruit per plant was varied significantly and ranged from 45.06 kg/plant to 72.52 kg/plant. The fruit of accession number SD Rah-01 produced the highest yield of 72.52 kg/plant. This is the 1^styear evaluation. To confirm the findings as well as to determine the yield performance the experiment should be continued.
