The invention is in the field of Brassica carinata breeding (i.e. Ethiopian mustard breeding), specifically relating to the inbred Brassica carinata cultivars designated Brassica carinata AGR044-312D and Brassica carinata AGR044-3A22. The present invention relates to seeds, plants or parts thereof, cells, methods of making, and uses of these cultivars and their progeny. AGR044-312D and AGR044-3A22 may exhibit improved yields relative to existing Brassica carinata commercial varieties. Other properties of these cultivars may include reduced levels of seed glucosinolate, improved disease resistance, and reduced tendency to lodging and pod shatter relative to existing commercial Brassica carinata varieties.
