This study was carried out to investigate the morphological characteristics of Sapota germplasm at germplasm centre of the Department of Horticulture, Bangladesh Agricultural University, Mymensingh-2202, Bangladesh and the duration of the study was April 2012 to April 2013. Five germplasm namely BAU Sapota-1, BAU Sapota-2, BAU Sapota-3, Deshi Sapota and Vietnam Sapota were taken for this study. The experiment was laid out in randomized complete block design (RCBD) with single factor experiment. Five treatments were used in this study and three replications were followed by each treatment. For this study, the mature leaves, fruits, flowers and seeds were collected randomly from the selected plants. Five plants from each of the selected germplasm were taken under study in field for recording their physical characteristics like plant height, stem circumference, tree spread, plant shoot girth and number of leaves per shoot and tree growth. Ten leaves, flowers, fruits and seeds from each of the selected germplasm were taken in the laboratory for recording their physical characteristics like leaf shape, leaf color, leaf margin, leaf apex, leaf length, leaf breadth, leaf lamina length, and leaf petiole length, flower type, flower color, number of flower per shoot, flower opening time and fruit setting time, fruit shape, fruit color, fruit smoothness, fruit sweetness, fruit pulp color, cavity of fruit, fruit length, fruit breadth, fruit fresh weight, % moisture content, total soluble solids and fruit yield per tree, seed length, and seed color. The leaf color was estimated by Royal Horticultural Society (RHS) color chart and the total soluble solids (TSS) content of Sapota pulp was measured by Refractometer. Also, the dry weight was estimated by transferring the cut pieces and air dried Sapota to an oven maintained at constant temperature of 780 C for about 72 hours. Analysis of variance was performed using MSTAT-C software and LSD test were also performed. Also, genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PVC) were estimated according to Burton and DeVane (1953), heritability in broad sense (h2 b), genetic advance (GA) were calculated following Hanson et al. (1956) correlation coefficients were estimated according to Al-Jibouri et al. (1958) and path coefficient analysis was done following Dewy and Lu (1959).
