RESUMO:

The sesame plant exhibits broad adaptability to diverse soil and climatic conditions, which has facilitated its dissemination across different regions worldwide. The seeds of this oilseed crop are characterized by high oil content and significant nutritional value, making them highly demanded for food applications and as raw material for industrial uses. Despite its productive and commercial potential, several constraints still limit crop performance, including low yield, capsule dehiscence, asynchronous maturation, issues related to seed quality, and the lack of systematic information on the genetic variability of cultivated genotypes, as well as limited access to germplasm bank data. In this context, the objective of this study was to evaluate the morphoagronomic and genetic variability of different sesame genotypes, aiming to generate information to support breeding programs and promote the sustainable expansion of the crop production chain. The analyses comprised morphological and agronomic traits of interest, as well as attributes related to seed quality, which are considered strategic for crop performance and the development of superior cultivars. Widely accepted phenotypic descriptors were used for species characterization, combined with genetic information available in the literature, enabling an integrated approach that associates morphoagronomic and genetic data. The results revealed substantial variability among the evaluated genotypes, particularly for traits such as plant architecture, growth cycle, yield, capsule characteristics, and seed physiological quality. This variability indicates a high potential for genetic gains through the selection and recombination of superior parents. The integration of field evaluations with genetic information is essential for identifying promising materials, especially those adapted to tropical environments and exhibiting greater yield stability. Furthermore, the study highlights the importance of seed quality—encompassing genetic, physical, and physiological components—as a key factor for successful crop establishment and for advancing breeding programs. In conclusion, the detailed characterization of variability in sesame genotypes represents a fundamental tool for guiding selection strategies, broadening the genetic base, and fostering the development of more productive cultivars adapted to the demands of both agricultural and industrial sectors.
