IPR AFRODITE - new oat cultivar with nematode resistance

The oat cultivar IPR Afrodite, resulting from a cross between CFT 2 and the inbred line ER 88144-1, is high-yielding, has grain quality traits that are relevant for food processing and industry, and is resistant to the root-knot nematode species Meloidogyne incognita, M. javanica, M. paranaensis and M. enterolobii.

Key words:
Avena sativa; breeding; grain processing quality
