Abstract/ Executive Summary:

Growth, yield and fruit characteristics of five aonla lines were recorded during the fruiting season of 2008-09 at the Fruit Research Farm of HRC, BARI, Joydebpur, Gazipur. The results on growth, yield and fruit characteristics of aonla are presented in table 1 and 2 respectively. Among the five aonla lines, EO-JOY 004 had the tallest plants (9.48 m) while EO-JOY 003 had the shortest (6.00 m). The maximum base girth, North-South and East-West spreading was found in EO-JOY 002. The highest yield (62.66 kg) was recorded from the line EO-JOY 005 followed by EO-JOY 004 (53.00 kg) and the lowest yield (18 kg) from the line EO-JOY 007. Among the lines, EO-JOY 005 produced the largest fruit (28.47 g) closely followed by EO-JOY 004 (26.65 g). The longest fruit was recorded from EO-JOY 005 (3 cm) followed by EO-JOY 004 (2.84 cm). The highest TSS was recorded in the fruit of the line EO-JOY 004 (12.40%) followed by EO-JOY 005 (12.10%) and the lowest from the line EO-JOY 007 (11.50%). In respect of taste, attractiveness, colour, crispiness and sweetness, quality fruits were obtained from the line EO-JOY 004 and EO-JOY 005 respectively.

Keywords: Collection, Evaluation, Aonla, Germplasm

Location: Joydebpur, Gazipur

Start Date: 01-06-2008

End Date: 31-05-2009

Program Area: Conservation and Biodiversity

Commodity: Aonla

Objectives:

To collect and evaluate different genotypes of aonla with the aim of developing suitable variety.

Methodology:

The experiment was conducted at the Fruit Research Farm of HRC, BARI, Joydebpur, Gazipur. Five aonla germplasm viz. EO-JOY 002, EO-JOY 003, EO-JOY 004, EO-JOY 005 and EO-JOY 007 were planted during 1992 to 1994 at 4 x 5m spacing. During 2008-09 the growth, yield and fruit characteristics were evatuated under this experiment. A single plant constituted a unit plot. The manures and fertilizers were applied at the rate of cowdung 25 kg, Urea 500g, TSP 400g and MP 450g per plant. All the nutrients were applied in two equal installments. Irrigation, weeding and other intercultural operations were done as and when necessary. Data on Plant height (m), base girth (m), plant spreading (m), no. of main branches/plant, number of fruits per kilogram, yield /plant, (kg), fruit colour, fruit shape, fruit wt. (g), fruit length (cm), fruit diameter (cm), TSS (%), flesh texture and taste of fruits were recorded from each plant and analyzed statistically.
