STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
None
Genus and species: Fragaria X ananassa Duch.
Variety denomination: ‘LBR 96 1’.
BACKGROUND OF THE INVENTION
‘LBR 96 1’ was obtained from the INSTITUTO NACIONAL DE INVESTIGACION AGROPECUARIA (National Institute for Agricultural Research) a breeding program located in Canelones, Uruguay. It originated from the cross between two advanced clones that was carried out in 2012 at the INIA Las Brujas facility in Canelones, Uruguay. It was selected in from a field of individuals in 2014 and later evaluated in preliminary and advanced agronomic trials against reference varieties, always under conditions representative of the production technology of the Salto area, Uruguay.
‘LBR 96 1’ was simultaneously characterized by its sanitary behavior against the natural infection of root/crown, foliar, and fruit pathogens (2014-2019). During 2018 and 2019, it was evaluated at the productive level in the producer's farms. During the last three years physical, chemical, and quality of fruit has been characterized. In 2020, the cultivar was registered, protected, and licensed.
Compared to its maternal parent ‘LBK 36.1A’ (INIA Mayte™), ‘LBR 96 1’ is more tolerant to soil, foliar and fruit diseases with superior fruit quality and agronomic behavior. According to the information available, ‘LBR 96 1’ would be recommended for the south production region of Uruguay.
The new cultivar ‘LBR 96 1’ has a superior performance than ‘LBK36.1A’ in early productivity (harvests July-September) and total production (harvest autumn, spring, and summer); in fruit quality, especially flavor; and health, due to its lower incidence of botrytis and powdery mildew in leaf and fruit.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
FIG. 1 illustrates the fruit of ‘LBR 96 1’ harvested July 2021 from a 5-month-old plant;
FIG. 2 illustrates plants of ‘LBR 96 1’ at 5 months of age cultivated with black plastic mulch and drip irrigation;
FIG. 3 illustrates plants of ‘LBR 96 1’ at 5 months of age with ripe fruit just before harvest; and
FIG. 4 illustrates production of stolons undergreenhouse with drip irrigation.
The colors of these illustrations may vary with lighting conditions and, therefore, color characteristics of this new variety should be determined with reference to the observations described herein, rather than from these illustrations alone.
