Abstract

The formation of new varieties of katokkon chili pepper through breeding was carried out in this study to obtain superior and quality crop yields. This study aims to determine the effect of the phenotypic characters of katokkon chili pepper resulting from polyploidization with colchicine. The study was conducted at the Malino Horticulture Seed Plantation Installation, Tinggimoncong District, Gowa Regency, South Sulawesi at an altitude of 1047 m above sea level. Katokkon chili polyploidy was induced by soaking katokkon chili sprouts in 0%, 0.05%, 0.1%, and 0.2% colchicine solution for 6, 12, 24, and 48 hours of soaking time. The results showed that treatment with 0.1% colchicine concentration and 48 hours of soaking time and 0.2% colchicine concentration and 24 and 48 hours does not cause any effect on the characters of length, width and thickness while on the characters of leaf color and the shape of the crown branching it can be seen that there is a difference in the color of the older leaves and the irregular shape of the leaves.
