PP25436
Genus and species: The strawberry cultivar of this invention is botanically identified as Fragaria×ananassa Duch.
Variety denomination: The variety denomination is ‘Merced’.
This invention relates to a new and distinctive short-day type cultivar designated as ‘Merced’. The new cultivar was the result of a cross performed in 2007 between two unreleased germplasm accessions, Cal 3.92-8 (unpatented) and Cal 2.95-4 (unpatented). Accession Cal 3.92-8 was chosen as a parent due to its very high productivity, large, firm, and high quality fruit, and very high plant vigor. Accession Cal 2.95-4 was chosen as a parent due to its compact plant habit and firm, flavorful fruit.
‘Merced’ was first fruited at an experimental orchard near Winters, Calif., in 2008, where it was selected, originally designated Cal 7.132-3, and propagated asexually by runners. Following selection and during testing, the plant of this selection was designated ‘C229’. It was later designated ‘Merced’ for introduction into commerce and for international registration and recognition. Asexual propagules from this original source have been tested at facilities in Watsonville, Calif., in Irvine, Calif., and to a limited extent in grower fields starting in 2009. The cultivar is stable and reproduces true to type in successive generations of asexual reproduction.
‘Merced’ is a short-day (June bearing) type cultivar that produces fruit over an extended period when treated appropriately in arid, sub-tropical climates. When treated with appropriate planting regimes, ‘Merced’ is similar to ‘Camarosa’ (U.S. Plant Pat. No. 8,708), but with greater productivity, higher quality fruit, less vigorous plant, and lighter colored fruit. It is also similar to ‘Ventana’ (U.S. Plant Pat. No. 13,469) and ‘Benicia’ (U.S. Plant Pat. No. 22,542) but having a more compact plant, later fruiting, superior fruit quality, and firmer, better flavored fruit.
The figures depict various characteristics of the ‘Merced’ cultivar.
‘Merced’ is typical of short-day strawberry cultivars and produces fruit over an extended period when treated appropriately in arid, subtropical climates. The production pattern for ‘Merced’ is similar to that for ‘Camarosa’ (U.S. Plant Pat. No. 8,708), although it is somewhat later to initiate fruiting with most cultural treatments. ‘Merced’ initiates fruiting substantially later than ‘Ventana’ (U.S. Plant Pat. No. 13,469) and ‘Benicia’ (U.S. Plant Pat. No. 22,542) when established in very early fall. ‘Merced’ will be of special interest for winter plantings, where ‘Camarosa’, ‘Ventana’, and ‘Benicia’ have been successful, and in summer plantings where ‘Chandler’ (U. S. Plant Pat. No. 5,262) and ‘Camino Real’ (U.S. Plant Pat. No. 13,079) have been successful.
Colletotrichum was evaluated in 2009.

‘Merced’ has been tested under a variety of cultural regimes, and optimal performance is obtained when nursery treatments and nutritional programs similar to those of ‘Camarosa’, ‘Ventana’, and ‘Benicia’ are used. In general, plants of ‘Merced’ are similar in vigor to ‘Camarosa’, and less vigorous than ‘Ventana’ with very early season planting. ‘Merced’ retains excellent fruit quality in summer planting systems.
When treated with appropriate planting regimes, ‘Merced’ has larger fruit and produces individual-plant yields greater than any of the comparison cultivars (Table 5). Commercial appearance ratings have also been better than those for all of the comparison cultivars, especially in comparison with ‘Camarosa’. Fruit from ‘Merced’ is substantially firmer than fruit from ‘Ventana’, but similar in firmness to the other comparison cultivars. Subjectively, ‘Merced’ has outstanding flavor. The fruit will be exceptional for both fresh market and processing, and will be useful for home gardening purposes.
Flower and plant measurements were obtained in April 2012. Fruit measurements were obtained in between May 10-20, 2012.
