Abstract/ Executive Summary:

The present study was conducted at the Germplasm Centre (GPC), Department of Horticulture, Bangladesh Agricultural University to study on some physiological characters of BAU-GPC released mango germplasm. Several mango germplasm of BAU-GPC released viz. BAU Aam-3, BAU Aam-5, BAU Aam-6, BAU Aam-8, BAU Aam-9, BAU Aam-11 and BAU Aam-12 were selected for this study. From the observation of mango characteristics after harvest, the maximum fruit showed ellipsoid shape and good external appearance where peeling quality was easy and skin was thin. From the study, the highest weight of fruit (309.3 g) and peel (51.18 g) were taken from BAU Aam-5 where the same germplasm also produced the highest on thickness of fruit (6.617 cm), breadth of stone (4.623 cm) and thickness of stone (2.437 cm). The highest weight of pulp (216.2 g), peel to pulp ratio (8.033) and edible portion (71.94%) were found from BAU Aam-3. BAU Aam-6 showed the highest on pulp to stone (5.047) and peel to stone (1.60) ratio whereas the highest breadth of fruit (6.650 cm) was found in BAU Aam-8. Non edible portion of peel (20.20%) and total (39.51%) were observed from BAU Aam-9. On the other hand BAU Aam-11 created the highest on length of fruit (12.44 cm), length of stone (10.17 cm) and non edible portion of stone (21.91%). The highest weight of stone (52.04 g) was also found from BAU Aam-12.

End Date: 00-08-2011

Program Area: Variety and Species

Commodity: Mango

Objectives:

1. To obtain information on some physiological characteristics of mango germplasm.

Methodology:

An experiment was conducted at the laboratory of BAU Germplasm Centre (GPC), Department of Horticulture, Bangladesh Agricultural University, Mymensingh during May to August 2011. Seven mango germplasm were selected for the study namely BAU Aam-3, BAU Aam-5, BAU Aam-6, BAU Aam-8, BAU Aam-9, BAU Aam-11 and BAU Aam-12 were used as in this study. These seven mango germplasms were considered as the experimental treatments and the total number of plants was 21. The experiment was laid out in MSTATC program under ANOVA-4 function with 3 replications. Single plants of each germplasm about four years old were considered as a replication. Ten well-matured fruits from each germplasm were collected randomly, brought to the laboratory in a polyethylene bag and were analyzed for various physical characteristics such as shape of fruit, external appearance, skin color, peeling quality, flesh color, weight of fruit (g), weight of pulp (g), weight of peel (g), weight of stone (g), length of fruit (cm), breadth of fruit (cm) thickness of fruit (cm), length of stone (cm), breadth of stone (cm) thickness of stone (cm), peel to pulp ratio, pulp to stone ratio, peel to stone ratio, edible portion (%) and non edible portion (%). The measurement in respect of fruit weight, fruit size and fruit shape were recorded with the help of Laboratory balance, slide calipers and by using a Catalogue of Mango Germplasms, IIHR, respectively. Data were analyzed and the means were separated by LSD test.

Achievement/Findings:

A significant variation on different stone size viz. length, breadth and thickness found to be the effect of different BAU-GPC mango germplasm. Among the seven BAU-GPC mango germplasm, peel to pulp ration range was 3.61 to 8.03, where the highest ratio was found from BAU Aam-3 and lowest was observed from BAU Aam-9. Similarly, the highest pulp to stone ratio (5.05) and peel to stone ratio (1.60) were recorded from BAU Aam-6. On the other hand, the lowest pulp to stone (3.14) and peel to stone (0.81) ratio were taken from BAU Aam-11 and 12, respectively.
