CHARACTERIZATION OF LOCAL AND EXOTLC MANGO GERMPLASM UNDER JOYDEBPUR CONDITION

Abstract

An investigation was carried out to Characterize 25 local and exotic mango germplasm at the Fruit Research Farm of Bangladesh Agricultural Research Institute (BARI). Joydcbpur. (Jazipur. during September. 2006 to August. 2007. The number of fruit set per panicle was maximUF71 11w Ananas (30.25) and minimum 11w Maldah (5.00). Individual fruit weight ranged from 110 g in Kalachini to 560 g in Fazli. Number of fruit per plant was maximum in BARI Aam-2 (198) and minimum in M-3896 (31). BARI Aam-2 yielded the highest (36.08 kg/plant) followed by Kent (27.77 kg/plant). Pahatun (25.97 kg/plant) and Maldah (25.8 kg/plant). The germplasm Mollika (79.69 %) and Kalachini (52.9 15%) had highest and lowest edible portion. Maximum pulp to stone ratio was found in Kalachini (0.89) and minimum in Shinduri (0.14). Kent contained the highest TSS (22.23%) and lowest TSS was in Totapuri (16.27%). Pulp p11 was the lowest in Ahaping (4.14%) and highest in Totapuri (5.42%), whereas Summer Behest had the highest (0.54%) titratable acidity. The germplasm Kalachini was top in respect of reducing sugar (7.37%) and non reducing sugar was the highest in Summer Behest (15.10%). Maximum sugar acidity ratio was noted in Totapuri (81 .5 I). Most of the germplasm under study performed very well in respect of yield, quality and pest & disease reaction. BARI Aam-l. BARI Aam-2. Kent and Ra.shunkoa were promising among the germplasm tested. Germplasm like Mollika. Ruby. Dashehari. Shinduri and M-3836 possessed attractive skin colour.
