This application claims priority under 35 USC 199(f) of Plant Breeder's Rights application No. 04-4344 filed Sep. 8, 2004 in Canada.
The present invention relates to a new and distinct apple cultivar designated as ‘SJCA38R6A74’. This cultivar belongs to the genus Malus×domestica.
The new cultivar ‘SJCA38R6A74’, also tested as A38R6A38, originated from a cross between ‘Linda’ and NY44428-5 (Jonamac), (FIG. 1). ‘SJCA38R6A74’ was asexually reproduced by grafting on selected rootstocks in L'Acadie and Frelighsburg in Quebec, and has been under evaluation since 1985 in replicated trails.
The fruit, leave and tree morphology of ‘SJCA38R6A74’ were stable during the evaluation period in Quebec (Frelighsburg and Acadie). ‘SJCA38R6A74’ is now an established and stable cultivar.
‘SJCA38R6A74’ is similar to its parents in terms of fruit size, tree vigor and harvest date. However, ‘SJCA38R6A74’ is distinguishable from its parents in several respects e.g. fruit over, blush and ground color, fruit shape, tree growing habit which is spreading drooping, in opposition with Linda (upright) and Jonamac (upright spreading). Furthermore, the fruits of ‘SJCA38R6A74’ are persistent and do not fall at maturity even after freezing at −20° C. in February (FIG. 7), contrary to its parents, of which some fruits drop at maturity and do not stay on tree after freezing.
‘SJCA38R6A74’ is adapted to the Northern climate and growing conditions similar to those of Frelighsburg and L'Acadie, Quebec.
‘SJCA38R6A74’ is a dessert apple (domestica Borkh.) type with improved firmness, crispness, high quality flesh and much longer shelf life than McIntosh and Cortland. The fruit flavor is pronounced and the fruits hang well on tree. The flesh is juicy, firm, crisp and resistant to bruising. The phenol (oxidative agent) content of the fruit is significantly less than the other known cultivars, even of Cortland which is the most popular apple variety for transformation and production of apple chips and fruit salad. No browning of the fruit occurs after cutting (even after 4-5 days at room temperature), without adding any chemical, which makes it an excellent candidate for fresh fruit slice, fruit salad, dried apple chips and processing (juice, cider).
The accompanying color photographs show typical specimens of the new variety at various stages of development as nearly true as it is possible to make in color reproductions.
The following is a detailed description of ‘SJCA38R6A74’, a new and distinct cultivar of Malus domestica. It is based on observations made during several growing seasons, from 1999 to 2004, in L'Acadie and Frelighsburg and an apple orchard located in Mont Saint-Grégoire, Quebec. The colors are described using The Royal Horticultural Society (R.H.S.) Colour Chart.
Chemical analysis of the ‘SJCA38R6A74’ fruits reveal low levels of phenols, as compared to well-known varieties, as shown in Table 1 below. In particular, This confers to the fruit its “no-browning” characteristic several hours after being cut with a stainless steel knife, until completely dried at room temperature.
A letter appearing in association with more than one value in a column of Table 1, indicates that the values associated with that letter are not significantly different from each other i.e. they differ from less than the least significant difference (LSD).
The fruit has a long shelf life. It keeps its firmness, juiciness and flavor at standard cold room for 4-5 months. Given all its advantageous characteristics, the ‘SJCA38R6A74’ fruit is recommended for fresh eating, fruit salad and processing (dried apple chips).
‘SCJA38R6A74’ trees are hardy at Frelighsburg, Quebec (latitude 45° N., longitude 72° W.), where the average winter minimum temperature is −25° C. There has been no sign of powdery mildew (Podosophaera leucotricha (Ell. & Ev.) Salm.), fireblight (Erwinia amylovora (Burr.) Winslow et al.) or scab (Venturia inaequalis) infections on leaves during the evaluation period.
‘SJCA38R6A74’ fruits are susceptible to bitter pit, particularly if the season is dry and no irrigation is provided. The fruits are resistant to water core and the flesh does not turn brown after bruising (FIG. 6). As stated earlier, and contrary to ‘McIntosh’, the fruits of ‘SJCA38R6A74’ do not drop at maturity and stay on the tree even at −20° C. (FIG. 7), which makes it a good candidate for “Ice Cider” Production.
