Abstract


The study was conducted to evaluate the physio-morphological variations of 21 pummelo genotype. The experiment was carried out at the existing plantation of Bangladesh Agricultural University Germplasm Centre, Mymensingh, during September 2014 to June 2015. Results showed that different genotype exhibited differently in their physio-morphological features. Genotype Thai Jambura exhibited highest leaf and petiole wing length (16.77 cm and 11.63 cm, respectively), while maximum number of anthers (44.33) were recorded in genotype Green skin. The heaviest and lightest fruits were recorded in genotype Hybrid (1283.33 g) and Accession-52 (300 g). While the maximum weight of non-edible portion (463.33 g), pulp to peel ratio (3.97), thickness of pulp (11.50 cm), amount of juice (366.67 ml), total soluble solids (TSS) (18.67%), number of seeds (114) and weight of seeds (58 g) were found in genotype Hybrid. Correlation coefficient study indicated that leaf length, breadth, petiole wing length, fruit weight, weight of non-edible portion, seed weight, seed number/fruit had positive and highly significant association with leaf breadth, petiole wing breadth, weight of non-edible portion, pulp thickness, total weight of seeds/fruit and number of fruits/plant, respectively. In respect of path analysis, leaf breadth, petiole wing length, fruit weight, average weight of seed, %TSS, seed number/fruit had positive direct effect on fruits/plant indicating its importance as a selection criteria
