Morpho-Agronomic Characterization, Sample Size, and Plot Size for the Evaluation of Capsicum chinense Genotypes

The Amazon is a center of diversity for Capsicum chinense Jacq., with wide genetic and morphological variability, but little exploration has been performed there to facilitate their improvement. This study aimed characterize evaluate C. genotypes the development cultivars by determining optimal size experimental plot minimum sample ensure precise estimation yield. A total 23 were evaluated, in multivariate analyses, plants characterized 21 descriptors eight quantitative traits related biometry recommended fruit evaluation was defined based on simulations subsample resampling semi-amplitudes confidence interval mean estimate. estimated modified maximum curvature method. similarity coefficients among ranged from 0.54 0.93, indicating that established clusters contained important information future crosses. According methodologies, 25 40 fruits should be sampled valid evaluations biometric traits. Experiments five per are test progenies species, ensuring good precision combined high selection accuracy yield
