Abstract

Seed production, weight of one thousand seeds and seed germination of oat cultivars were evaluated in trials in 2000 and 2001. The experimental design was of randomized blocks with three repetitions. In the first year, the following cultivars were evaluated: IAC-7, UFRGS-17, UFRGS-14, UPF-16 and OR-2, and in the second year: IAC-7, UFRGS-17, UPF-16, UFRGS-15 and UFP-19. Seeding was done on 21 June 2000 and 30 May 2001. Seed harvest was done at the stage hard grain and, subsequently, processed. Cultivar IAC-7 was the earliest one in both years, even with the increase in culture cycle for all cultivars during the second year. As with the weight of one thousand seeds, seed production and seed germination increased during the second year. Although there were no significant differences among the cultivars in agricultural year 2001, the general aspect of cultivar UFRGS-17 was outstanding from the others, having high grain production and excellent seed germination on both year evaluated. Great values for seed germination were found for both years, and statistical differences among the cultivars were observed only in the first year.
