Abstract/ Executive Summary:

The experiment was conducted at the Garmplasm Centre of Fruit Tree Improvement Project (FTIP), Department of Horticulture, Bangladesh Agricultural University, Mymensingh during the period from December, 2004 to July, 2005. The experiment consisted of three factors viz. two variety (Amrapali and Mallika), three flush age (0-3, >3-6, >6-9, and >9-12 months) and four side orientation (north, south, east and west) of flushes. The experiment was designed in three factor Randomized Complete Block Design with three replications. The treatments of the study significantly influenced all the parameters related to bearing habit of mango. The length of panicle (36.76 cm), individual fruit weight (365 g) and TSS (25.10) were found to be maximum in Mallika in south sided >9-12 months flush. The number of flowers per panicle (2203), number of fruits at pea stage (25.0), marble stage (23.0) and at harvest (12.0) were highest in >9-12 months aged flush of Amrapali at southern orientation. There were no flowers and fruits produced by 0-3 months aged flushes from any side orientation.

Keywords: Flush maturity, Shoot orientation, Cultivar and mango

Location: Garmplasm Centre of Fruit Tree Improvement Project (FTIP), Department of Horticulture, Bangladesh Agricultural University, Mymensingh

Start Date: 00-12-2004

End Date: 00-07-2005

Program Area: Variety and Species

Commodity: Mango

Objectives:

1. To identify the appropriate flush age, orientation in two popular varieties viz. Amrapali and Mallika.

Methodology:

The experiment was carried out at the Garmplasm Centre of Fruit Tree Improvement Project (FTIP), Department of Horticulture, Bangladesh Agricultural University, Mymensingh during the period from December, 2004 to July, 2005. The experiment consisted of three factors, namely varieties (Amrapali and Mallika), flush ages (0-3, >3-6, >6-9 and >9-12 months) and different orientations of shoots (north, south, east and west). The experiment was laid out in three factors Randomized Complete Block Design with three replications. Ten years old 12 plants of each variety were used in this experiment. The shoots of different flushes were tagged according to identity of leaf colors of the flush leaves as light green with short leaves (0-3 months old flushes), pale green with normal leaves (>3-6 months old flushes), mat green with normal leaves (>6-9 months old flushes) and dark green with normal leaves (>9-12 months old flushes). Data were recorded on length of panicle (cm), number of flowers per panicle, number of fruits at pea stage, number of fruits at marble stage, number of fruits at harvest, weight/fruit (g) and total soluble solid (TSS). The data were statistically analyzed by F-test and DMRT was used for evaluation of the treatment effects.

Achievement/Findings:

The treatments of the study significantly influenced all the parameters related to bearing habit of mango. The length of panicle (36.76 cm), individual fruit weight (365 g) and TSS (25.10) were found to be maximum in Mallika in south sided >9-12 months flush. The number of flowers per panicle (2203), number of fruits at pea stage (25.0), marble stage (23.0) and at harvest (12.0) were highest in >9-12 months aged flush of Amrapali at southern orientation. There were no flowers and fruits produced by 0-3 months aged flushes from any side orientation.
