Strawberry plant named ‘LBR 96 1’

[0001] Genus and species: Fragaria X ananassa Duch.

[0002] Variety denomination: ‘LBR 96 1’.

[0003] None

[0004] ‘LBR 96 1’ was obtained from a breeding program located in Canelones, Uruguay. It originated from the cross between two advanced clones that was carried out in 2012 in Canelones, Uruguay. It was selected 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.

[0005] ‘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.

[0006] Compared to its maternal parent ‘LBK 36.1A’ (commercially known as INIA Mayte™—unpatented), ‘LBR 96 1’ is more tolerant to soil, foliar and fruit diseases with fruit quality and agronomic behavior. According to the information available, ‘LBR 96 1’ would be recommended for the south production region of Uruguay.

[0007] The new cultivar ‘LBR 96 1’ exhibited early productivity (harvests July-September) and total production (harvest autumn, spring, and summer); and showed a high fruit quality, especially flavor; and health, due to its lower incidence of botrytis and powdery mildew in leaf and fruit.

[0008] Comparison is made between new cultivar ‘LBR 96 1’ and commercial variety ‘San Andreas’ (U.S. Plant Pat. No. 19,975). ‘LBR 96 1’ has had higher early yields between June and October than that of ‘San Andreas’. ‘LBR 96 1’ has also maintained a higher total yield throughout growing season of Spring until end of January than that of ‘San Andreas’. During trials ‘LBR 96 1’ maintained an average Soluble Solids of 0.6 (g/100 mL) acidity, 0.8 (N) firmness, and 7.6 brix which provides a balanced fruit. In comparison during trials, ‘San Andreas’ maintained an average soluble solids of 0.7 (g/100 mL) acidity, 0.9 (N) firmness, and 7.9 brix. In addition, ‘San Andreas’ is very susceptible to anthracnose, botrytis, leaf spots, bacteriosis and soil diseases whereas ‘LBR 96 1’ has proven resistance to anthracnose, leaf spots, bacteriosis, powdery mildew, and botrytis.

[0009] Throughout several generations of asexual propagation, ‘LBR 96 1’ has been observed to be stable and retain its distinctive characteristics, and reproduce and remain true to type in successive generations of asexual production.

[0014] 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.

[0015] The following description is that of a plant age of approximately 3.5 months and is based on observations made during the 2021 growing seasons in Las Brujas, Canelones, Uruguay. It should be understood that the characteristics described will vary somewhat depending upon cultural practices and climatic conditions and can vary with location and season. Measurements are the average for the plants of the new cultivar and may vary according to the stage of development. Color terminology follows The Royal Horticultural Society Colour Chart, London (R.H.S.) (Sixth Revised Edition, 2015).
