Polyploidy was declared as an attempt to obtain a new variety with the hope of increasing the quality of diploid (2n) plants by changing the chromosome arrangement to become tetraploid (4n) using the 2n chili seed soaking method for 30 days at a concentration of colchicine, namely K0 = 0.0% (control); K1 = 0.1%; K2 = 0.2%; and K3 = 0.3%. Data from the analysis of variance (ANOVA) stated that there was a very significant effect (**) on all observed variables. The results of the analysis on the variable percentage of seed germination showed that the treatment with a concentration of 0.0% was 92.20% with the number of chromosomes 24 (2n) and 0.1% as much as 26.20% with the number of chromosomes 48 (4n), while the increase in colchicine concentration (0.2% to 0.3%) has a lethal effect so that no chili seeds germinate (0.00). The average concentration of 0.1% treatment was higher with a large stem diameter, a large number of branches, a small number of leaves, more chlorophyll content with a dark green dun color, a larger number of stomata, a smaller leaf area, shorter flowering, more number of stomata, smaller leaf area, age shorter flowering, more glossy fruit color, shorter physiological maturity, longer fruit stalk size, longer fruit size, larger fruit diameter, heavier fruit, a higher number of harvested fruits, a heavier harvested fruit, number of seeds per fruit, and the weight per 100 seeds is heavier when compared to the control treatment (K0 = 0.0), which is very different.
