‘Saint-Laurent d’Orléans’ is a new June
bearing strawberry cultivar (Fragaria
X ananassa Duch.) released by Agriculture and Agri-Food
Origin
‘Saint-Laurent
d’Orléans’, tested as FIO9624-11, is a selection from a cross
between ‘L’Acadie‘ (Khanizadeh et
al., 1999) and a selection (SJ8916-1 x Pink Panda), which was bred
in 1996 by S. Khanizadeh. ‘Saint-Laurent d’Orléans’ has been
tested at the Agriculture and Agri-Food Canada sub-station in
L’Acadie, Quebec since 1997, and in controlled semi-commercial sites
by our research partner Les Fraises de l’Île d’Orléans in Île
d’Orléans, Québec and also by Meiosis Ltd.

Description
Plants
of ‘Saint-Laurent d’Orléans’ are of medium vigor, have a flat
globose growing habit, and produce 4-5 inflorescences per crown.
Plants can survive winter air temperatures to –30
°C
with 10 cm straw mulch cover. Petioles are short with three, medium
green, cupped and obtuse leaflets, with slightly acute teeth. The
terminal leaflets have a 1.25 length: width ratio. The leaves are
medium to dark green with very weak to medium blistering between the
veins. ‘Saint-Laurent d’Orléans’ produces perfect white medium-
to large-sized flowers. The
five petals (occasionally six to seven) are touching and petals are
slightly longer than wide. The
fruit shape is conic or globose conic. The flesh is medium to dark red
almost throughout and firm. Fresh fruit store well (up to 4-5 days) at
room temperature and longer under refrigeration.
‘Saint-Laurent
d’Orléans’ was tested in several locations but the data presented
here are from the replicated trials (four replicates) in commercial
fields (Les
Fraises de l' Île d'Orléans Inc., St-Laurent, Île d'Orléans,
Quebec
)
since
1999. ‘Saint-Laurent
d’Orléans’ produces significantly higher yield and larger fruit
size than ‘
The
fruit are also firmer, with lighter red skin color, and have longer
shelf life at room temperature than ‘
‘Saint-Laurent
d’Orléans’ demonstrates a higher degree of resistance to leaf
diseases [scorch (Diplocarpon
earlina Ell. & Ev.) and leaf spot (Mycosphaerella
fragariae (Tul.) Lindau] compared with ‘
The
phenolic compounds of various fruits have been widely shown to protect
plant tissues against external stresses and contribute to disease
resistance (Wang
et al., 1994; Mayr et
al., 1997; Kalt
et al., 1999). These compounds may act as flavoring agents,
colorants or antioxidants to extend shelf life and enhance
preservation quality (Baldwin et al., 1995).
Area
of adaptation and uses
‘Saint-Laurent
d’Orléans’ is recommended for Eastern Central Canada, especially in
areas where the climate is similar to that in the strawberry production
areas of Quebec.
Typically, strawberry
production in Quebec
occurs in areas with winter
temperatures as low as –30
°C
and warm, humid summers with an unpredictable mixture of sun and rain.
‘Saint-Laurent d’Orléans’ plant performance is good in both
well-drained and poorly-drained soils regardless of soil texture. The
fruit is ideal for pick-your-own, fresh market, or shipping.
