Abstract

An experiment was conducted to study ten mango (Mangifera indica L.) germplasm during July 2018 to May 2019 in Shibganj, Chapainawabganj. Fruit characteristics varied greatly among the studied mango germplasm. The germplasm, Fazli was the largest fruit (Length 14.47 cm, Breadth 8.40 cm, Thickness 7.80 cm) having maximum fruit weight 743.33 g and the highest pulp quantity 614.67 g with highest pulp/peel & stone ratio (4.80) among the germplasm. Ripen mango contained the highest TSS (°Brix) in the germplasm Langra (20.67%) which was better than Fazli. The largest stone was recorded in Fazli (Length 11.60 cm, Breadth 4.87 cm, Thickness 2.70 cm) having maximum weight 66 g whereas minimum in Khirsapat 39.13 g among the germplasm. From biplot analysis it was recorded that there was a positive correlation between fruit weight and pulp weight in the germplasm Fazli. From genetic diversity analysis it was revealed that Fazli had higher genetic similarity and Ashina had lower genetic similarity with another germplasm. The dendrogram generated from the unweighted pair group arithmetic average (UPGMA) cluster analysis broadly placed 10 mango cultivars into four major clusters. The cluster size varied from 1 to 5. Cluster I was the largest cluster comprising of five germplasm. The tendency of clustering among mango cultivars revealed that they have strong affinity towards further breeding program.
