【 摘 要 】

Spiked pepper presents a high yield of essential oil with useful biological properties for human health and agriculture. In order to evaluate the morphoagronomic variability and, afterwards, to select genotypes for plant breeding and cultivation, thirteen clones were propagated. Thus, spiked pepper cuttings were rooted under greenhouse, transferred to a nursery and, afterwards, planted at the experimental area. The evaluations were carried out in two harvest seasons. The evaluated morphoagronomic traits were number of leaves per branch, leaf length, leaf width, diameter of the oldest branch, plant height, number of orthotropic branches, number of plagiotropic branches, internode length, fresh and dry matter, yield of essential oil and dillapiole content. The analysis of variance and the Scott-Knott test were utilized for data analysis and comparisons among clones and parentals were carried out through genetic and experimental variation coefficients. Fresh matter (first season), number of orthotropic branches and diameter of the the oldest branch (second season) presented variability. The Scott-Knott test detected variability for fresh matter, dillapiole content (first season), diameter of the oldest branch and number of orthotropic branches (second season). The yield of essential oil and the dillapiole content were higher for the clones than for the parentals. In conclusion, the clones showed adaptability to the soil and climate conditions of Belém, Pará State, Brazil; the harvest time influenced the oil yield and the dillapiole content; the variance analysis evidenced uniformity and productivity for the evaluated clones, suggesting they can be recommended for cultivation on small-scale production systems in this location.
