Abstract

‘UCD Mojo’ is an extreme day neutral cultivar of a strawberry plant adapted for summer-planting that provides high yields.

Description

Genus and species: The strawberry plant of this invention is botanically known as Fragaria x ananassa Duchesne.
Variety denomination: The variety denomination is ‘UCD Mojo’.
BACKGROUND
The terms ‘extreme day-neutral’ (EDN) and ‘summer-plant’ are synonyms for photoperiod insensitive cultivars adapted for summer-plant production. EDN cultivars flower under short and long daylengths and are adapted for contra-season production. While many day neutral (DN) cultivars flower over the summer months, many do not perform well or produce high yields when planted at the height of summer. The specific factors that differentiate DN from EDN cultivars are unknown but appear to be genetically complex. Empirical testing (phenotyping in summer-plant production systems) was conducted on cultivars to identify summer-plant-adapted hybrids and to determine the genotype of hybrids for the PERPETUAL FLOWERING (PF) mutation, which enables flowering under long daylengths and is necessary for production in contra-season production systems, e.g., summer planting for fall production.
BRIEF SUMMARY
This invention relates to a new and distinct extreme day-neutral (or summer-plant) strawberry cultivar designated as ‘UCD Mojo’. ‘UCD Mojo’ is adapted for contra-season and protected culture production in California and other parts of the world. ‘UCD Mojo’ originated from a cross that is believed to have occurred in the winter of 2012 between ‘07C203P001’ (unpatented) and ‘08C150P009’ (unpatented). It is unknown which plant is the female parent. The parent varieties were identified and the pedigree reconstructed using DNA forensic approaches involving exclusion analysis of DNA fingerprints of the strawberry germplasm collection of about 1,200 individual cultivars maintained by the applicant/assignee in Davis, Calif. Seeds of the cross were harvested from greenhouse-grown plants in the spring of 2012 and germinated in June 2012. Seedlings were transplanted to a greenhouse in July 2012 and transplanted to the field in October 2012. Daughter plants (clones) of ‘UCD Mojo’ were initially produced and harvested from the mother plant in 2013. ‘UCD Mojo’ has since been preserved by asexual propagation.
The plant of this selection was initially tested as ‘12C166P002’ and later called ‘EDN19’ for evaluation in field trials.
‘UCD Mojo’ was initially selected based on the intensity of flowering under long day lengths and high summer temperatures in Winters, Calif. It was discovered using phenotypic analysis and genotyping with single nucleotide polymorphism (SNP) markers that ‘UCD Mojo’ is homozygous for the dominant allele of the PF mutation, which is a single dominant mutation that is necessary and sufficient for day-neutral flowering in descendants of a male wild ecotype Fragaria virginiana subsp. glauca plant that was collected in the Wasatch mountains in Utah (see, e.g., Bringhurst et al., Calif. Agric. 34: 12-15, 1980; Bringhurst et al., Acta Hortic. 265: 35-42, 1989). ‘UCD Mojo’ was determined to be well-adapted for summer-plant production.
Comparison variety ‘UCD Finn’ (U.S. Plant patent application Ser. No. 17/160,297, filed Jan. 27, 2021) is heterozygous for the PF mutation, as is comparison variety ‘Portola’ (U.S. Plant Pat. No. 20,552). Fruit of ‘UCD Mojo’ has higher sugar-to-acid ratios and is therefore sweeter than fruit from ‘Portola’. ‘UCD Mojo’ is significantly more acidic than ‘UCD Finn’. ‘UCD Mojo’ also has firmer fruit compared to ‘Portola’ and a fruit total soluble solids content that is significantly greater than that of ‘Portola’. ‘UCD Mojo’ is later flowering than ‘UCD Finn’. The fruit color of ‘UCD Mojo’ is more orange than that of ‘Portola’ and ‘UCD Finn’.
‘UCD Mojo’ was genotyped with a 50,000-SNP array (Hardigan et. al., Frontiers in Plant Science 10:1789, 2020). After quality- and LD-pruning, 31,212 SNP markers with well-separated codominant genotypic clusters were selected for further analysis. The analyses confirmed that ‘UCD Finn’ is genetically distinct from parent varieties ‘07C203P001’ and ‘08C150P009’, ‘UCD Finn’, ‘Portola’, and over 500 additional varieties that were tested. ‘UCD Mojo’ is also shorter and a more spreading plant type than parent variety ‘07C203P001’. In addition, the fruit of ‘UCD Finn’ is long and conic compared to shorter, round conic fruit of ‘07C203P001. Stolon (runner) production for ‘UCD Mojo’ is less that than of parent ‘08C150P009’. ‘UCD Mojo’ is also more susceptible to Verticillium Wilt and more resistant to Macrophomina relative to parent ‘08C150P009’.
‘UCD Mojo’ is maintained by annual asexual propagation by stolons in Winters, Calif.

 DETAILED DESCRIPTION
Based on field testing of day-neutral hybrids in 2016, ‘UCD Mojo’ was selected for advanced testing in replicated yield trials in 2017, 2018, and 2019. The 2017 and 2018 yield trials were performed in 24-plant (small) plots, whereas the 2019 yield trials were performed in 50-plant (large) plots. The most important observations and conclusions from these yield trials are enumerated below.
The cumulative marketable fruit yields of ‘UCD Finn’ and ‘UCD Mojo’ were comparable to those of ‘Portola’ in both conventional and organic production systems (Tables 1 and 2). We did not observe statistically significant differences in cumulative marketable fruit yields among cultivars within or among environments.
Yields for all cultivars were substantially lower in organic than conventional production systems (Tables 1 and 2). Yields for ‘UCD Finn’ and ‘UCD Mojo’ were greater than ‘Portola’ in large-plot conventional trials. The difference for ‘UCD Mojo’ was significant (p=0.005), whereas the difference for ‘UCD Finn’ was not (p=0.1)). The marketable fruit percentages of ‘UCD Finn’, ‘UCD Mojo’, and ‘Portola’ were not significantly different (Table 2).

Cultivars were grown in randomized complete blocks experiment designs with two replications/entry and multiple harvests/environment. Cultivars were grown in small (24 plant) plots in Ventura, CA in 2017 and Oso Flaco, CA in 2017 and 2018, and large (50 plant) plots in Guadalupe, Ventura, and Oso Flaco, CA in 2019. Contrasts are shown for comparisons of UCD Finn and UCD Mojo to Portola and each other.
‘UCD Finn’ and ‘UCD Mojo’ were significantly sweeter than ‘Portola’ (Tables 3 and 4). When compared to ‘Portola’, mean Brix (°Bx) increase was 1.21 for ‘UCD Finn’ (p=0.0009) and 0.95 for ‘UCD Mojo’ (p=0.0106). The improved sweetness was a significant factor in the selection of ‘UCD Finn’ and ‘UCD Mojo’ for commercial advancement.
‘UCD Finn’ and ‘UCD Mojo’ were also significantly firmer than ‘Portola’ (Tables 3 and 4). When compared to ‘Portola’, the mean increase in fruit firmness was 52.3 g for ‘UCD Finn’ (p=0.0005) and 81.8 g for ‘UCD Mojo’ (p≤0.0001).
The titratable acid (TA) percentages of ‘UCD Finn’ and ‘UCD Mojo’ were not significantly different from ‘Portola’; however, ‘UCD Mojo’ was significantly more acidic than ‘UCD Finn’ (Table 4).
The sugar-to-acid ratio (TSS/TA) was significantly greater for ‘UCD Finn’ than ‘UCD Mojo’ and ‘Portola’ (Table 4). The higher the ratio the greater the perceived sweetness; hence, ‘UCD Finn’ had greater perceived sweetness than ‘UCD Mojo’. The sugar-to-acid ratios for ‘UCD Mojo’ and ‘Portola’ were not significantly different.

Cultivars were grown in randomized complete block experiment designs on five farms over two years (five year × location combinations) with two replications/entry, two harvests/environment, and one to three subsamples/harvest. Least square means were estimated for cultivars across locations and years. Fruit firmness (g of force) was measured on fresh fruit samples in the field using a handheld penetrometer with a 3 mm probe. Degrees Brix (° Bx) was measured on fresh fruit samples in the field using a handheld refractometer (Fresh) and previously frozen fruit samples in the laboratory using a benchtop refractometer (Frozen). Titratable acid (TA) percentages were measured on previously frozen fruit samples in the laboratory using a benchtop titrator.

The improved sweetness and firmness of ‘UCD Finn’ and ‘UCD Mojo’ persisted in postharvest storage (Tables 5-7). ‘UCD Finn’, ‘UCD Mojo’ were significantly sweeter and firmer than ‘Portola’ over 14 days in cold storage. As expected, fruit weight decreased for each cultivar over time in cold storage. The weight loss from desiccation was significantly greater for ‘Portola’ than ‘UCD Finn’ (Table 6). The fruit weight loss for ‘UCD Mojo’ was not significantly different from ‘Portola’ or ‘UCD Finn’. We did not observe significant differences among cultivars for leakage or mold percentages.
