Morphological Characterization of Sixty Mango (Mangifera indica) Germplasm of Bangladesh

Abstract

A study was conducted in the research field of Regional Horticulture Research Station, Bangladesh Agricultural Research Institute, Chapainawabganj to know the morphology of 60 germplasm of mango leaf, inflorescence, flower and fruits. A great morphometric variation was observed in the leaf. The inflorescences were pyramidal or conical in form except for Khudikhirsha, Narikeli and Himsagor which were cylindrical. The ratio of hermaphrodite and male flowers showed variation. Fruit characters like length, breadth, weight and colour were studied. The highest fruit weight and length were found in Fazli (760 g and 15.17 cm) and the lowest fruit weight was recorded in Modhuchoski (128.50 g). Variation in fruit colour was also recorded among the germplasm. The highest percentage of Total Soluble Solid (TSS) in the germplasm khodikhirsapat (24.33%) and the maximum stone weight (69.87g) was recorded in Fazli. The longest fruit length was observed in the germplasm of Ashwina (13.03 cm). The highest fruit breadth was observed in the germplasm Fazli (9.87 cm). The present investigation has established that the morphological characters can be used as a tool for the taxonomic discrimination of varieties of Mangifera indica.
