[Comparative studies of oat cultivars from Southern Brazil: effect of grain morphology on industrial yield].

The purpose of this work was to study the effect of grain morphology of oats on their industrial yield. The five cultivars studied: CTC3, UFRGS7, UFRGS14, UPF7 and UPF16 were grown in three localities with different soil and climate conditions, for two consecutive years. The parameters evaluated in the oat samples before and after dehulling were grain size and shape (by image analysis), comparing them to industrial yield, weight of a thousand kernels and hectoliter weight.
