Abstract
BackgroundProductivity and quality of crops can be increased through polyploidy plants induced by colchicine. The use of colchicine has never been applied to Katokkon pepper, a local red pepper variety from North Toraja Indonesia. This pepper is characterized by its unique shape like the small-bell pod type of paprika and its strong spicy taste. Therefore, this study aimed to determine the effects of colchicine treatment on the ploidy level and morphological characters of Katokkon pepper. ResultsFlow cytometer analysis showed that all colchicine concentration treatments ranging from 0.025 to 0.1% with 24 h immersion time generated two plant groups based on their ploidy level; 50% of the total treatment plants was diploid while the rest plants were mixoploid. All colchicine treatment plants were significantly different in their width of stomata guard cells from the control plant. The effect of colchicine was also significantly on the plant height, thickness of fruit flesh, and the number of fruits per plant. ConclusionsThe results of this study showed that colchicine treatment had a significant effect on the ploidy level and several morphological characters of the Katokkon pepper. The colchicine treatment increased the number of fruits per plant and thicker flesh of fruits but reduced the size and weight of Katokkon pepper. Our findings provide essential information to obtain tetraploid Katokkon plants through colchicine treatment in further research. This study benefits as a preliminary step for increasing the productivity and quality of the local red peppers in Indonesia.

Effect of colchicine on ploidy level of Katokkon pepper In this study, we identified that all colchicine treatment plants were significantly different in their width of stomata guard cells from the control plants (Table 1)
Effect of colchicine on morphological characters of the Katokkon pepper The morphological characters of the Katokkon control and treatment plants were analyzed based on the plant habitus and fruit
Summary
Productivity and quality of crops can be increased through polyploidy plants induced by colchicine. The use of colchicine has never been applied to Katokkon pepper, a local red pepper variety from North Toraja Indonesia. This pepper is characterized by its unique shape like the small-bell pod type of paprika and its strong spicy taste. Red pepper is a horticulture crop with various benefits in human life, including food, medicine, and the economy. It contains many essential nutrients and bioactive compounds with multiple benefits such as antioxidant, antimicrobial, antiviral, anti-inflammatory, and anticancer [11]. Much effort is still needed in cultivation and other aspects to improve productivity and quality
