‘Harogem’ is an exceptionally attractive, very firm, high quality, mid- to late season apricot (Prunus armeniaca L.) suitable for the fresh market. It is cold hardy, resistant to brown rot [Monilia fructicola (Wint.) Honey], perennial canker (Leucostoma spp.), and skin cracking but moderately susceptible to bacterial spot [Xan-thomonas pruni (E. F. Sm.) Dows]. It was introduced in 1979 to meet the need for a better adapted, more consistently productive, cold hardy and disease tolerant cultivar for the Ontario fresh market.
