Blackberry, an Attractive Deep Purple Potato Variety with Resistance to Common Scab and Extreme Resistance to Potato Virus Y

Abstract

Blackberry is a tablestock variety with uniquely deep purple skin and flesh. The tubers have an attractive, uniform, round shape with common scab resistance and low incidence of internal defects. It also carries the Rysto marker for extreme resistance to potato virus Y. When baked or microwaved, the tuber flesh is a brilliant deep purple with an enjoyable mild taste. It was selected in 2011 from a cross between two breeding lines COMN07-W112BG1 and MSU200-5PP. Although primarily oriented towards the fresh market, Blackberry is an all-purpose variety that also has the ability to chip out of the field. Yields are high under irrigated conditions and specific gravity averaged 1.068 in on-farm trials in Michigan.
