‘Mojave’ is typical of short-day (June bearing) strawberry cultivars and produces fruit over an extended period when treated appropriately in arid, subtropical climates. When treated with appropriate planting regimes, ‘Mojave’ has larger fruit and produces individual-plant yields greater than that of ‘Camarosa’ (U.S. Plant Pat. No. 8,708). It further produces similar quantities of fruit per plant but develops larger and higher quality fruit than ‘Ventana’ (U.S. Plant Pat. No. 13,649). ‘Mojave’ also produces a larger fraction of marketable fruit than any of the comparison cultivars.

1. A new and distinct cultivar of strawberry plant having the characteristics substantially as described and illustrated herein.
|
Genus and species: The strawberry cultivar of this invention is botanically identified as Fragaria×ananassa Duch.
Variety denomination: The variety denomination is ‘Mojave’.
This invention relates to a new and distinctive short-day type cultivar designated as ‘Mojave’. This new cultivar was the result of a cross performed in 2004 between the cultivar ‘Palomar’ (U.S. Plant Pat. No. 19,472) and unreleased germplasm accession Cal 1.57-601 (unpatented). Accession Cal 1.57-601 was chosen as a parent due to its large, dark colored, and high quality fruit and also due to its high early-season productivity. ‘Mojave’ was first fruited at a center near Irvine, Calif. in 2005, where it was selected, originally designated Cal 4.44-603, and propagated asexually by runners. Following selection and during testing, the plant of this selection was designated ‘C227’. It was later designated ‘Mojave’ for the purposes of introduction into commerce. Asexual propagules from this original source have been tested at Watsonville, Calif., in Irvine, Calif., and to a limited extent in grower fields starting in 2007. The cultivar is stable and reproduces true to type in successive generations of asexual reproduction.
‘Mojave’ is typical of short-day (June bearing) strawberry cultivars and produces fruit over an extended period when treated appropriately in arid, subtropical climates. When treated with appropriate planting regimes, ‘Mojave’ has larger fruit and produces individual-plant yields greater than that of ‘Camarosa’ (U.S. Plant Pat. No. 8,708). It further produces similar quantities of fruit per plant but develops larger and higher quality fruit than ‘Ventana’ (U.S. Plant Pat. No. 13,469). ‘Mojave’ also produces a larger fraction of marketable fruit than any of the comparison cultivars.
The figures depict various characteristics of the ‘Mojave’ cultivar.
‘Mojave’ 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 ‘Mojave’ is similar to that of ‘Ventana’ and ‘Palomar’, although it is somewhat earlier to initiate fruiting with most cultural treatments than ‘Camarosa’. ‘Mojave’ initiates fruiting slightly later than ‘Ventana’ when established in late fall. ‘Mojave’ will be of special interest for winter plantings, where ‘Camarosa’, ‘Ventana’, and ‘Palomar’ have been successful, and in summer plantings where ‘Pajaro’ (U.S. Plant Pat. No. 4,538) and ‘Chandler’ (U.S. Plant Pat. No. 5,262) have been successful. Color descriptions are drawn to the Munsell Color Chart.
Fruiting plants of ‘Mojave’ are similar in morphology to ‘Camarosa’, although slightly more open and erect and somewhat smaller than ‘Ventana’, throughout most of the production season with most cultural treatments. ‘Mojave’ plants are larger than those of ‘Palomar’ and similar in size to those of ‘Camarosa’ in most production environments. Comparative statistics for foliar characteristics near mid-season are given for ‘Mojave’ and three comparison cultivars in Table 1. Individual leaflets for ‘Mojave’ are larger than all three comparison cultivars. Leaves (including petioles) for ‘Mojave’ are similar in length to ‘Ventana’ and ‘Camarosa’, but with shorter petioles and larger leaflets. The leaves are longer than those for ‘Palomar’. The adaxial (upper) surfaces of leaves for ‘Mojave’ are similar in color to ‘Camarosa’ and darker than ‘Ventana’ leaves at mid season, whereas the abaxial (lower) surface is somewhat lighter in color. Leaves of ‘Mojave’ have consistently more concavity than ‘Camarosa’, less concavity than ‘Palomar’ and are similar to those of ‘Ventana’. ‘Mojave’ leaves have similar shape and number of serrations at mid season as the comparison cultivars.

‘Mojave’ is moderately resistant to powdery mildew (Sphaerotheca macularis), Verticillium wilt (Verticillium dahliae), and common leaf spot (Ramularia tulasnei). It is moderately susceptible to Anthracnose crown rot (Colletotrichum acutatum), and is highly susceptible to Phytophthora crown rot (Phytophthora cactorum) (Table 2 ). When treated properly, it has tolerance to two-spotted spider mites (Tetranychus urticae), equal to that for the comparison cultivars. ‘Mojave’ is tolerant to strawberry viruses encountered in California.

‘Mojave’ is similar to other California short-day strawberry cultivars (e. g. ‘Ventana’, ‘Camarosa’, and ‘Palomar’) in that it will flower over an extended period and into spring or summer, given appropriate local temperature and horticultural conditions. With very early plantation establishment (before October 1 in California), ‘Mojave’ produces fruit as early as ‘Ventana’ and ‘Palomar’, and earlier than ‘Camarosa’, with similar seasonal productivity to ‘Ventana’. With later plantation establishment ‘Mojave’ initiates fruit later than ‘Ventana’, and is similar in production timing to ‘Camarosa’ and ‘Palomar’, with slightly lower seasonal productivity than ‘Ventana’. Comparative statistics for flower and fruit characteristics near mid-season are given for the four cultivars in Table 4. The primary flowers for ‘Mojave’ are smaller than ‘Ventana’ and ‘Camarosa’, with a calyx that is usually larger than the corolla on primary fruit, and much smaller than ‘Palomar’. The calyx for ‘Mojave’ varies in position, but frequently has a slight indent later in the season. The fruit shape for ‘Mojave’ can vary but is larger than the comparison cultivars, and is typically a short to medium and very symmetric conic. It is easily distinguished by fruit shape from ‘Camarosa’ (shortened and flattened conic), or ‘Ventana’ (medium symmetrical conic), and ‘Palomar’ (short symmetrical conic). External and internal fruit color for ‘Mojave’ is distinctly darker than the comparison cultivars (Table 3). Achenes vary from yellow to dark red, and are even with the fruit surface or slightly indented.
‘Mojave’ 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 ‘Palomar’ are used. In general, plants of ‘Mojave’ are equally vigorous as ‘Camarosa’ although ‘Mojave’ initiates growth more rapidly after transplant. ‘Mojave’ is less vigorous than ‘Ventana’, with very early season planting, but more vigorous than ‘Palomar’. ‘Mojave’ retains excellent fruit quality in summer planting systems.
When treated with appropriate planting regimes, ‘Mojave’ has larger fruit and produces individual-plant yields greater than that of ‘Camarosa’. It produces similar quantities of fruit per plant, but develops larger and higher quality fruit than ‘Ventana’ (Table 5 ). Commercial appearance ratings have been equal to or better than those for all of the comparison cultivars, and are substantially larger than ‘Camarosa’ and ‘Ventana’. ‘Mojave’ produces a larger fraction of marketable fruit than any of the comparison cultivars. Fruit for ‘Mojave’ is slightly less firm than fruit from ‘Ventana’, and much less firm than the other comparison cultivars. Subjectively, ‘Mojave’ has outstanding flavor. The fruit will be exceptional for both fresh market and processing, and will be useful for home gardening purposes.
