Abstract

‘SJM150’ (St-Jean Morden 150) is a new rootstock resulting from a cross made in 1960 between Malus baccata ‘Nertchinsk’ and ‘M.26’ (‘Malling 26’ = M.16 · M.9). It is a new dwarfing apple rootstock developed at theAgriculture andAgri-Food Canada (AAFC) Research Station, St-Jean-sur-Richelieu, Québec. It produces dwarf trees larger than ‘Malling 9’ (M.9) but smaller than ‘Malling 26’ (M.26). It was released because of its superior hardiness, ease of propagation, and similar to better efficiency and precocity compared with ‘M.26’ and ‘M.9’ in sandy loam soil. ‘SJM150’ produces very low or no suckers compared with ‘M.9’ and the same amount of burr knots compared with ‘M.9’ and ‘M.26’.
