Progeny testing, both formal and informal, has been a component of the University of Florida strawberry breeding program. Informally, the potential of numerous parental combinations has been assessed by growing small populations of each combination, and then ranking these populations according to visual impression. Formal progeny testing, where variables are measured on seedlings in a replicated measurement block, was used during the 1987-88 season. Several families were identified as promising, based on an analysis of yield, fruit size, firmness, and appearance data.

Strawberry Breeding

Strawberries are one of the most important food crops grown in Florida, with a harvested area of ≈10,000 acres. The University of Florida strawberry breeding program develops cultivars adapted to this region and its particular weather conditions, with a major aim of increasing overall quality. The objective of this study was to compare the fruit of advanced breeding selections to those of commercial cultivars, for compositional attributes. Seven different strawberry genotypes were compared at harvest and after 7 days at 4 °C across multiple harvest dates during two consecutive years. Compositional attributes were highly influenced by year, harvest date within a year, genotype, and storage. Overall, compared with other genotypes, selection FL 09-127 exhibited consistently higher soluble solids and total sugar (TS) contents at harvest and after cold storage. Higher ascorbic acid (AA) and phenolic contents at harvest were observed in selection FL 07-193. However, its anthocyanin content was among the lowest. In contrast, FL 10-47 exhibited relatively low AA content at harvest but consistently high total anthocyanins (TACs) and total phenolic (TP) contents after storage. Overall, results from this study provide valuable information to the breeding process by identifying new genotypes with improved compositional attributes combined with suitable quality characteristics after cold storage.

Resistance to Colletotrichum crown rot (CCR, caused by Colletotrichum gloeosporioides) among commercial strawberry cultivars is variable, and increasing host resistance is a goal of the strawberry breeding program at the University of Florida. Twenty-eight accessions of Fragaria virginiana and F. chiloensis, the progenitor species of the cultivated strawberry (F. × ananassa), were evaluated for CCR resistance on artificially inoculated plants in a field trial, along with cultivars and breeding selections. Accessions PI 612320, PI 612323, and PI 551736 and selections FL 10-128 and FL 10-129 had no mortality in either of two seasons. The most susceptible genotypes had mortality between 75 and 100%. In a separate growth-chamber evaluation, seven genotypes were inoculated by spraying a spore suspension onto the crown or by injecting the suspension directly into the crown tissues. Mortality was higher using the injection method but the ranking of the genotypes was similar for both methods, indicating that resistance is expressed within crown tissues. Among the seven genotypes, selections FL 10-128 and FL 10-129 had the lowest mortality regardless of inoculation method, illustrating that a high level of resistance can be found within the cultivated germplasm.

Caladiums are valued in landscapes and containers for their colorful and variable-shaped leaves. Two types of caladium cultivars exist in commercial production: fancy- and lance-leaved. ‘Florida Sweetheart’ is the most popular lance-leaved commercial cultivar of all colors. It produces wide lance leaves with a rosy color and relatively large tubers. ‘Florida Red Ruffles’ is the most popular red, lance-leaved commercial cultivar among caladium growers, greenhouse growers, and nurseries. It has excellent sunburn tolerance. Both cultivars were introduced by the University of Florida (UF) caladium breeding program. This 9-page fact sheet was written by Zhanao Deng, and published by the UF Department of Environmental Horticulture, August 2013. http://edis.ifas.ufl.edu/ep481

For many years peach orchards were limited to geographic areas with an adequate number of hours below 45 degrees Fahrenheit, during the colder months, also known as “Chill hours” (University of Florida, Institute of Food and Agricultural Sciences, 2017). In 1952, a stone fruit breeding program started at the University of Florida with a goal of breeding trees which would produce peaches and nectarines to grow in Florida (Olmstead, Chaparro, Anderson, Williamson, & Ferguson, 2016). In recent decades, horticulturalists have developed peach varieties requiring fewer chill hours. This trait now allows peaches to be commercially produced in Florida (Olmstead et al., 2016). Growing peaches in Florida has been identified as a practical option for citrus farmers who have lost groves to citrus greening. As a result, much of the peach production in Florida is centralized areas where citrus was once prevalent, Central and South Central Florida. However, there are also some peach orchards in North and North Central Florida (Olmstead et al., 2016).   The growing conditions in Florida, have given Florida peaches unique characteristics that make them an ideal spring-time snack. In this document, we will discuss the unique Florida peach, including its smaller size, seasonality, tree-ripened sweetness, and health benefits. Lastly, we will leave you with recommendations to keep your Florida peaches fresh as long as possible.

Two lance-leaf caladium cultivars are to be released from the ornamental breeding program at the University of Florida. `Red Ruffles', whose pedigree is Red Frill × (`Red Frill' × `Candidum Jr.'), has elongated medium red leaves with ruffled green margins. Plants are upright with strong petioles, have leaf blades 25 cm long and 14 cm wide, and attain a height of 61 cm when grown in full sun in the field. Plants have more leaves and are more cold tolerant than `Red Frill', the major red lance-leaf cultivar of commerce. Tuber yields of `Red Ruffles' are similar to `Red Frill' but less than `Rosalie', with production indices of 95.0, 97.8, and 121.0, respectively. Foliage of `Red Ruffles' is more upright and less likely to elongate under reduced light than the other cultivars. `Irish Lace', an F2 selection from a cross of “Candidum Jr.' × “Red Frill', has elongated dark green leaves with heavily ruffled margins, which are etched with a thin red border. Leaf blades are 26 cm long and 8 cm wide and have heavy substance. Plant height is 65 cm in the field. Tuber yields of `Irish Lace' are greater than `White Wing', a major green/white cultivar. Use of a green caladium would be as a border or a mixture with red or white lance-leaf cultivars.

Fall Application

Ethephon solutions at various concentrations were sprayed on strawberry plants, Fragaria × ananassa Duch., in late fall to determine if fruit yield was affected in the subsequent growing season. Plants of the day-neutral (everbearing) cultivar Centennial sprayed with 100 ppm solution had increased fruit yield and number compared with control plants. Selection 107 M 6 from the University of Guelph strawberry breeding program produced greater fruit yields with a 1000-ppm spray but fruit number was not increased. Yield and fruit number of Redcoat and selection 31 B 38 were not affected by ethephon sprays.Key words: Strawberry, ethephon

Plum production has good potential for commercial growers and homeowners in Florida and other mild winter areas throughout the Gulf coast. However, most seasonal plums on the market are from California and will not perform well enough in Florida to produce fruit. From 1998 to 2001, plum cultivars have been released from the University of Florida's breeding program that adapt to our mild winters and high disease pressures. Because they have cropped reliably and produced high quality fruit, these cultivars are recommended for trial in Florida. The names of all University of Florida plum cultivars begin with the prefix 'Gulf.' These cultivars are Japanese type plums (Prunus salicina Lindl.) and have resistance to plum leaf scald (Xylella fastidiosa) and bacterial spot (Xanthomonas campestris). Fruit size is satisfactory (about 1 1/2 to 2 in. diameter) and fruit quality is good. They ripen in early to late May or about two weeks before California plums. This document is HS895, one of a series of the Horticultural Sciences Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.
