Varieties used for comparison: 'Malling 26' and 'Ottawa 3'
Summary: 'SJP84-5198' is an apple rootstock variety which produces more basal shoots in the stool bed than both reference varieties and has a lower tendency to produce suckers than 'Malling 26'. The dormant one-year-old shoots of 'SJP84-5198' are less flexible with smaller lenticels than those of 'Malling 26'. The growing tip of the shoot is white for 'SJP84-5198' while it is red for 'Ottawa 3'. Pubescence of the upper side of the shoot tip leaves is dense for 'SJP84-5198' while it is very sparse for 'Ottawa 3'. 'SJP84-5198' has larger leaves than 'Malling 26' and smaller leaves than 'Ottawa 3'. The orientation of leaves of 'SJP84-5198' is downwards while it is outwards for 'Malling 26' and upwards to outwards for 'Ottawa 3'. Pubescence on the lower side of the leaves is very sparse for 'SJP84-5198' while it is dense for 'Malling 26'. Bud burst occurs earlier for 'SJP84-5198' than either reference variety. 'SJP84-5198' has a larger flower diameter than 'Malling 26'. 'SJP84-5198' produces fruit which is symmetrical in side view and smaller than that of 'Malling 26' whose fruit is asymmetrical in side view. The fruit of 'SJP84-5198' has weaker ribbing than that of 'Ottawa 3'.'SJP84-5198' has a deeper and narrower eye basin than 'Ottawa 3'. The fruit stalk of 'SJP84-5198' is thicker and shorter than that of 'Ottawa 3' and thinner and longer than that of 'Malling 26'. 'SJP84-5198' has a more shallow and narrower stalk cavity than 'Ottawa 3'. The surface of the fruit is hammered to bumpy for 'SJP84-5198' while it is smooth for the reference varieties. 'SJP84-5198' has a greater amount of skin over colour than 'Malling 26'. The colour of the fruit flesh is yellowish for 'SJP84-5198' while it is white for 'Malling 26' and cream for 'Ottawa 3'.

Origin & Breeding History: 'SJP84-5198' originated from a cross between 'Robusta 5' and 'Malling 27' ('Malling 13' x 'Malling 9'). The cross was conducted in 1975 at Agriculture and Agri-Food Canada (AAFC) in Saint-Jean-sur-Richelieu, Québec as part of the AAFC Apple and Rootstock Breeding Program. 'SJP84-5198' was selected based on its winter hardiness, ease of propagation, pest resistance and disease resistance. It has been evaluated on an ongoing basis since 1984 in several locations including Frelighsburg, Mont-Saint-Grégoire, l'Acadie and Dunham, Québec.
Tests & Trials: The test and trial for 'SJP84-5198' was conducted within stool beds and self rooted orchards at l'Acadie Research Sub Station of Agriculture and Agri-Food Canada in l'Acadie, Quebec during the summers of 2000 and 2003. The trial included 3-4 root stocks of each variety and 4 self rooted trees of the candidate variety, 5 self rooted trees of reference variety 'Malling 26' and 8 self rooted trees of reference variety 'Ottawa 3'. All colour characteristics were determined using the 2001 Royal Horticultural Society (RHS) colour chart and measured characteristics were based on ten measurements except for the measured leaf characteristics of 'Malling 26', which were base on 8 measurements.
