Abstract—The present study aimed to study the Karyomorphological analysis of seven species of Passiflora (P. edulis, P. foetida, P. subpeltata, P. quadraqularis, P. ligularis, P. leschenaultii, and P. tripartitia). The species are exhibited the diploid status with difference in chromosome number, i.e., P. edulis f. flavicarpa (2n = 18), P. foetida var. foetida (2n = 20), P. subpeltata (2n = 18), P. quadrangularis (2n = 18), P. ligularis (2n = 18), P. leschenaultii (2n = 18) and P. tripartita (2n = 18) with perceptible difference in the karyotypic features, total chromosome length (TCL), and the total arm Percentage (TF%). Low TF% (38.05%) observed in varieties of P. foetida point to the evolved nature of the species. Idiogram were constructed based on relative length of chromosomes.

摘要-The本研究旨在研究的七种的Karyomorphological分析西番莲（毛竹，P.蚓，P. subpeltata，P. quadraqularis，P. ligularis，P. leschenaultii和P. tripartitia）。该种表现出二倍体状态，其染色体数不同，即可食的P. edulis f。flavicarpa（2 n = 18），P. foetida var。foetida（2 n = 20），P。subpeltata（2 n = 18），P. quadrangularis（2 n = 18），P。ligularis（2 n = 18），P。leschenaultii（2 n = 18）和P.tripartita（2 n = 18）在核型特征，总染色体长度上有明显差异（TCL），以及总手臂百分比（TF％）。低TF％（38.05％）在品种观察P.蚓点到物种的演进性质。根据染色体的相对长度构建图。
