Resumo: Many factors may interfere in the quality of millet seeds; however, it is not known whether the location at different positions of the panicle may affect this quality. This study aimed to evaluate the quality of millet seeds produced at different positions of the panicle using uniformity, 1,000-seed mass, water content, X-ray, germination, seedling length, seedling dry matter mass, cold and health tests. The panicles were divided into five equidistant portions (proximal 1, proximal 2, intermediary, distal 1 and distal 2), starting from the panicle insertion. It was observed that there are differences among the positions of the seeds in the panicles related to the physical, physiological and health characteristics. The seeds located at the ends of the panicles presented a lower mass and physiological potential. The highest occurrence of Fusarium sp. was verified in the seeds from the proximal 1 portion, what might indicate a possible cause for the reduction in the physiological potential. Seeds from the intermediary portion present a higher mass, percentage of intact seeds and physiological potential. KEY-WORDS: Penissetum glaucum (L.) R. Br., X-ray test, seed health.

Objetivou-se avaliar a qualidade de sementes de milheto produzidas em diferentes posições da panícula, por meio dos testes de uniformidade, massa de 1.000 sementes, teor de água, raios X, germinação, comprimento de plântulas, massa de matéria seca das plântulas, de frio e de sanidade. As panículas foram divididas em cinco porções equidistantes (proximal 1, proximal 2, intermediária, distal 1 e distal 2), iniciando-se a partir da inserção da panícula. Observou-se que existem diferenças entre as posições das sementes nas panículas relacionadas às características físicas, fisiológicas e sanitárias. As sementes localizadas nas extremidades das panículas apresentaram menor massa e potencial fisiológico. A maior ocorrência de Fusarium sp. foi verificada nas sementes da porção proximal 1, o que pode indicar uma possível causa na redução do potencial fisiológico. Sementes na posição intermediária apresentam maior massa, porcentagem de sementes íntegras e potencial fisiológico. PALAVRAS-CHAVE: Penissetum glaucum (L.) R.
