Benefits of technology

This patent describes a new strawberry variety called "UCD Finn" that was developed in California and can be produced in other parts of the world. It was created by crossing two other strawberry varieties, and has specific characteristics that make it suitable for contra-season and protected culture production. The variety has been tested and found to have higher sugar-to-acid ratios, firmer fruit, and a darker red color compared to other varieties. It is maintained by asexual propagation and can be distinguished from other varieties using DNA forensic approaches. The technical effects of this patent are a new strawberry variety with specific characteristics that make it suitable for high-quality production in different parts of the world.

Problems solved by technology

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.

Embodiment Construction

[0013]Based on field testing of day-neutral hybrids in 2016, ‘UCD Finn’ 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.

[0014]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.

[0015]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), ...

Abstract

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

Description

[0001]Genus and species The strawberry plant of this invention is botanically known as Fragaria x ananassa Duchesne.[0002]Variety denomination: The variety denomination is ‘UCD Finn’.BACKGROUND[0003]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 p...
