Narrative

The strawberry variety Bolero was raised at Horticulture Research International East Malling in 1987 by Dr David Simpson and Judi Bell. It has a complex pedigree involving Redgauntlet, Wiltguard, Gorella, Cardinal and Selva. Selected in 1988 because of its very high fruit quality, Bolero (formerly EMR63) was released to industry in 1996 following extensive trialling.The fruit is very firm and has a good shelf life; consistently better than the standards in tests at East Malling. The flavour is superior to Tango and Evita. Berries have a very regular, conical shape which tends to become elongated towards the end of the season. They are very glossy with orangered skin colour.In autumn-planted trials at East Malling, Bolero was more productive than all the standard varieties in 1992 and 1995 but produced a lower yield than Evita in 1994. In spring-planted grower trials in 1995 the yield from Bolero was similar to Evita despite a later planting date.Average fruit size is smaller than Evita with many of the berries falling in the medium size category (25-35 mm) but this is partly due to their elongated shape. In all trials Bolero has produced a higher proportion of class 1 fruit than the standard varieties.From an autumn planting the season is later than Rapella but is more condensed, In a spring planted trial, at HRI Efford in 1995, the cropping pattern of Bolero was very similar to CalypsoWith its excellent fruit quality and particularly good shelf-life, Bolero is well suited for supermarket sales and all other types of retail outlets. Plants are moderately vigorous and runner production is better than most other everbearing varieties. Pollen production is excellent which is one of the reasons for the consistently high proportion of class 1 fruit, regardless of extremes in weather.Bolero has an advantage over most other everbearers on the market in that it exhibits a good level of resistance to powdery mildew (Sphaerotheca macularis). An added bonus is a useful level of resistance to crown rot (Phytophthora cactorum) and wilt (Verticillium dahliae).The excellent fruit quality and good disease resistance of Bolero will make it a strong competitor with other mid-season ever-bearer varieties such as Evita, Calypso and Rapella. It does not have the early flush of production typical of Tango.
