Together these attributes confer a good overall consumer acceptability on ‘Red Rhapsody’. Fruit of ‘Red Rhapsody’ are firm to very firm, yet juicy, with a soluble solids (measured in degrees Brix):titratable acidity ratio similar to ‘Florida Radiance’, ‘Strawberry Festival’, and ‘Suncoast Delight’ ( Table 2). The calyx is slightly larger than the fruit diameter. They are glossy, with a blackish red external color (53A Royal Horticultural Society, 1995) and a medium-red internal flesh color (43A Royal Horticultural Society, 1995). Fruit are mostly conical in shape and much longer than they are wide (mean length/width ratio = 1.29). ‘Red Rhapsody’ produces fruit that are larger than ‘Strawberry Festival’, ‘Suncoast Delight’, and ‘Florida Radiance’ ( Table 1). This exposure makes the fruit easy to harvest, but also increases the fruit’s exposure to raindrop impact. Fruit are well displayed beyond the leaf canopy. The compact plant habit and medium-long, stiff pedicels produce the inflorescence at the same level as the foliage, resulting in many exposed flowers. The terminal leaflet is much longer than broad (mean length/width ratio = 1.10) and has an acute shape of the leaf base. Color of the upper side of the leaf is medium green (137A Royal Horticultural Society, 1995), with blistering and glossiness absent or weak. Stipule anthocyanin coloration is absent or very weak. ‘Red Rhapsody’ has medium vigor with a compact but spreading plant habit and a sparse to medium density of foliage with a terminal leaflet that is concave in cross-section. ‘Red Rhapsody’ is a sister line of ‘2010-119’, which is one of the parents of ‘Florida Beauty’ ( Whitaker et al., 2017).
First selection was at Maroochy Research Facility, Nambour, Queensland, during the 2010 season (May–September) and was identified as ‘Selection 2010-114’ before being released as ‘Red Rhapsody’. ‘Red Rhapsody’ was first selected as a desirable genotype based on earliness of fruit, large fruit size, good flavor, high resistance to bruising, attractive fruit appearance, an open but compact plant habit, erect trusses, and readily detachable fruit that are displayed outside the leaf canopy. ‘Suncoast Delight’ was used as the male parent because of its early and continuous production smooth, regular, conic fruit shape and dark fruit color. ‘Suncoast Delight’ is a selection made at Bundaberg, Queensland, from a cross produced in Florida, and was the product of a collaborative breeding effort between the University of Florida and DAF. ‘2005-063’, an unreleased breeding line selected in 2005, was used as a female parent because of its high yield potential, day neutrality under subtropical temperatures, large fruit size, and medium-red fruit color. ‘Red Rhapsody’ originated from a 2009 cross between DAF breeding line ‘2005-063’ and ‘Suncoast Delight’ ( Herrington and Price, 2010). 1), we focused on selecting for these traits while maintaining levels of other traits at or above commercially acceptable threshold levels. In the development of ‘Red Rhapsody’ ( Fig.

When this information was combined with genetic parameters, they found ( Herrington et al., 2014) the key drivers of greater profitability compared with the current profitability in subtropical Southeast Queensland were having a greater proportion of yield early in the season and having a larger fruit size. Herrington et al., (2012) analyzed the production and marketing system in Queensland in relation to the effect of changes in plant traits on the notional profitability of production.
Producer profitability is a key need for a stable production system. Supply volumes influence market prices and profitability to the producer. The commercial desirability of strawberry cultivars for producers, distributors, retailers, and consumers depends on many traits. Numerous plant losses sometimes occur, especially when demand for early supply of runners results in premature digging and lower quality runners. The average fruit size of ‘Strawberry Festival’ is less than ‘Florida Radiance’, but the latter is more difficult to establish in the field. ‘Florida Radiance’ is marketed in Australia as ‘Florida Fortuna’. ‘Strawberry Festival’ ( Chandler et al., 2000) and, more recently, ‘Florida Radiance’ ( Chandler et al., 2009) were introduced to Queensland and rapidly became major early-season cultivars with fruit and plant attributes desirable to growers. Queensland’s winter strawberry ( Fragaria × ananassa Duch.) industry would benefit by having an early ripening, more profitable cultivar to replace current cultivars.
