Flooding Tolerance in Oats

ABSTRACT The oat (Avena sativa L.) crop has been increasing its acreage in Southern Brazil very rapidly in the last decade. Areas novel to the crop, e.g., lowland areas, however, cannot be developed unless flooding-tolerant genotypes are available. With this goal, two experiments were designed using eight commercial genotypes: UPF 14, UPF 16, UFRGS 7, UFRGS 14, UFRGS 16, UFRGS 18, CTC 2 and ORLA 9248. Plants were subjected to flooding for at least 30 days and evaluated for plant height (PH), root length (RL), root dry matter (RDM) and total dry matter (TDM). The genotypes evaluated showed very different responses to flooding.
