Peppers belongs to Capsicum genus and have a lot of different varieties. They can be different uses such as potted ornamental plants. Retail market for this type of pepper requires the development of a greater number of commercial cultivars with adequate ornamental characteristics as well as an extended shelf life (post-production). Ethylene exposure causes adverse effects in ornamental pepper post-production. Then, the goal of this study was to select ornamental pepper elite lines (Capsicum

The experiment was conducted at the Laboratory of Plant Biotechnology of the Center for Agricultural Sciences of the Federal University of Paraíba, Areia, PB. The experiment was arranged in a completely randomized design. Eight elite lineages and two control cultivars evaluated at three times 48, 72 and 96 hours after ethylene exposure were disposed in a split-plot arrangement. Each treatment was composed of ten repetitions. The data were submmited to analysis of variance, Scott-Knott criteria (5%), and regression analysis. The leaves demonstrated to be more sensitive to ethylene while fruits were more insensitive. It is recommended selection of UFPB lines: 56.8.24.1; 56.26.15.1 and 56.26.34.1 to participate in trials tests aiming at registration of new ethylene-insensitive cultivars.
