Study on physico-morphological characteristics of Betel vine cv. Khasia pan genotypes grown in northeastern hilly region of Bangladesh

The current study was conducted over two consecutive growing seasons (2021 and 2022) at the Spices Research Sub-Station, Citrus Research Station, Jaintapur, Sylhet, Bangladesh to evaluate the growth, morphology, and yield attributes of the betel vine cv. Khasia pan genotypes. The experimental design employed was a Randomized Complete Block Design (RCBD) with three replications. Data were collected five times throughout the leaf harvesting period. Five khasia pan genotype designated as PB Jai-001 through PB Jai-005 were collected from different locations of Bangladesh. The results highlight significant variations in vine height, girth, internodal length, branching patterns, leaf morphology, and yield attributes. PB Jai-002 showed the most vigorous growth, with the tallest vines, thickest girths, highest number of lateral branches, and largest leaf area across two consecutive growing seasons (2021 and 2022). PB Jai-004 also performed strongly, particularly in leaf size and overall leaf yield, producing the highest number of leaves per hectare. In contrast, PB Jai-005 consistently lagged behind in all growth and yield parameters, including vine height, branching, leaf size, and yield, indicating significant genotypic variation among the evaluated genotypes.
