Abstract/ Executive Summary:

An investigation on some bio-chemical characteristics of twenty two mango germplasms namely, Rad, Farooquebhog, Neelumbori, Neelumboti, Chausa, Mallika, Tommy Atkin, Hybrid-10, Shindhu, Mixed special, Gopalbhog, Surmai Fazli, Langra, Khirsapat, Amrapali, BARI mango-1, Kent, Keitt, Palmar, Kalibhog and Sindhu was carried out at the Germplasms Center of Fruit Tree Improvement Project, Department of Horticulture, Bangladesh Agricultural University, Mymensingh during December, 2002 to December, 2003. All the germplasms were chemically analysed and highly significant differences were recorded among the germplasms. Farooquebhog possessed maximum moisture content whereas Mixed special had the highest titratable acidity. The germplasms Pahlam was top in the list in case of TSS and pH but Rad and Amrapali was also top in respect of reducing sugar and non-reducing sugar, respectively. On the other hand, maximum total sugar and sugar/acidity ratio were noted in Rad and Amrapali, respectively. Moreover, in terms of vitamin C content Shindhu was the best one among the germplasms studied.

Start Date: 00-12-2002

End Date: 00-12-2003

Program Area: Variety and Species

Commodity: Mango

Objectives:

To assess detail information on the bio-chemical characteristics of some mango germplasms grown at Mymensingh, which were not earlier evaluated.

Methodology:

The experiment was carried out at the Germplasms Center of Fruit Tree Improvement Project (FTIP), Department of Horticulture, Bangladesh Agricultural University, Mymensingh during December, 2002 to December, 2003. Twenty two germplasms of mango namely, Rad, Farooquebhog, Neelumbori, Neelumboti, Chausa, Mallika, Tommy Atkin, Hybrid-10, Shindhu, Mixed special, Gopalbhog, Surmai Fazli, Langra, Khirsapat, Amrapali, BARI mango-1, Pahlam, Kent, Keitt, Palmar, Kalibhog and Sindhi were used in the study. These 22 mango germplasms were considered as the experimental treatments and the total number of plants was 66. Both the distances between plant to plant and row to row were 6m in Randomized complete Block Design with three replications. The soil was silty-loam in texture belonging to the Old Brahmaputra Flood plain series having pH 5.5 to 6.8. The crop was manured and fertilized as per schedule. All other intercultural operations were done as and when necessary. Ten well matured fruits from each variety collected randomly, brought to the Laboratory in a polyethylene bag and were analyzed for various bio-chemical characteristics such as percent moisture, percent TSS, pH, percent total sugar, percent reducing sugar, percent non-reducing sugar, percent titratable acidity and vitamin-c. The measurement in respect of percent TSS, percent total sugar, percent reducing sugar, percent titratable acidity and vitamin-c were recorded with the help of Abbe refractometer by anthrone method, by dinitrosalicylic acid method , by the method and according to the method of Plummer, respectively. During data collection age of plants was 10-12 years. Data were analyzed and the means were separated by LSD test.
