Survey, Collection and Evaluation of Some Coloured Mango Germplasm

M. S. Islam

Abstract/ Executive Summary:

An experiment on the performance of 16 coloured mango lines was conducted at the Regional Horticulture Research Station, Chapai Nawabganj during 2009-10. These lines were collected from different places of Chapai Nawabganj district under ADB-TFT project during 2002. Among these lines CM-016 has been released as a variety namely BARI Aam 7. Among the lines, 9 lines are included under report. Wide variations were observed among the lines qualitative and quantitative characters of fruit. The heaviest fruit (737 g) was produced by CM-001 whereas the lightest fruit was got under CM-011 (197 g). The highest no. of fruits per tree (75) was produced by CM-002 whereas the lowest no. of fruits (2.33) was produced by CM-008. The highest yield (37.17 kg/ plant) regarding fruit weight was produced by CM-001 and that was followed by CM-002 (15.72 kg/pl. The lines CM-002, CM-006, CM-011 and CM-017 produced attractive with coloured fruits whereas the remaining had poor attractive and dull coloured fruits. CM-011 obtained maximum edible portion (68.10 %). The highest TSS (21.70 %) was found in CM-011 while the lowest TSS (15.17%) was noted under CM-013.

Keywords: Survey, Evaluation, Colored mango, Germplasm

Location: Regional Horticulture Research Station, Chapai Nawabgan

Start Date: 00-00-2009

End Date: 00-00-2010

Program Area: Variety and Species

Commodity: Mango

Objectives:

To identify mango lines with the attractive colour as well as good qualitative characters.

Methodology:

The experiment was conducted at Regional Horticulture Research Station, Chapai Nawabganj during 2009-10. The grafts of 10 coloured mango germplasm were planted in July 2002. Planting distance was maintained at 5 m X 5 m in both ways. Trees were fertilized twice a year as per recommendation of Hossain (1989). Two full cover sprays was done against diseases and insects. Other intercultural operations were done as and when necessary. Up to writing this report, 9 lines were ripe among 10 lines as they bore fruits.

Achievement/Findings:

Highly Significant variation was among the germ plasm regarding qualitative characters of fruits. Significantly the heaviest fruit (737.0 g) was produced by CM-001 followed by CM-007 (349.67 g) whereas the lightest fruit (90.0 g) was obtained from CM-011 CM-001 produced both maximum peel (170.0 g) and the heaviest stone (85.0 g). On the other hand, minimum (30.67 g) peel was recorded from CM-011 but the lightest (26.0g) stone was found in CM-006. CM-06 obtained maximum edible portion (71.91%) followed by CM-008 (71.00 %) whereas minimum edible portion (59.59%) was obtained from CM-017. The highest TSS (21.70 %) was found in CM-011 closely followed by CM-006 (21.33%). Minimum TSS (15.13%) was noted for CM-013. The highest number of fruits (75) per tree was produced by CM-002 followed by CM-001 (56). The lowest number of fruits (2.33) was obtained from CM-008. CM-001 had the highest yield (33.17kg/tree) CM-008, CM-003 and CM-013 produced the least yield whereas others were moderate regarding yield. Singh (1990) reported that the yield of mango varies greatly depending upon the variety, tree condition and agro-climatic condition in a region.
