Varieties used for comparison: 'Valor' and 'Seascape'
Summary: The stolons of 'Marvel' have medium intensity of anthocyanin colouration and dense pubescence whereas those of 'Seascape' have absent or very weak anthocyanin colouration and sparse pubescence. The leaves of 'Marvel' have absent or weak blistering while those of 'Valor' have medium blistering. Glossiness of the upper side of the leaves is absent or weak for 'Marvel' while it is medium for 'Valor' and medium to strong for 'Seascape'. The base of the terminal leaflet is acute for 'Marvel' whereas it is obtuse for both reference varieties. The inflorescence for 'Marvel' is positioned at the same level as the foliage whereas for 'Seascape', it is positioned above the foliage. The flowers of 'Marvel' have a calyx which ranges in size from the same size to larger in relation to the corolla whereas those of 'Seascape' have a calyx which is smaller in relation to the corolla. The width of the band without achenes on the fruit of 'Marvel' is absent or very narrow while it is medium to broad on the fruit of 'Seascape'. The achenes are positioned above the fruit surface for 'Marvel' while they are level with the fruit surface for 'Valor'. The time of beginning of flowering and of fruit ripening is mid-season for 'Marvel' whereas it is early for 'Seascape'.

Origin & Breeding History: 'Marvel' is the result of a controlled cross conducted in Santa Cruz County, California, USA, as part of an ongoing breeding program. The cross was made in 2001 between the variety 'PS-1269' and the variety 'PS-2880'. 'Marvel' was selected from a controlled breeding plot in Ventura County, California in the fall of 2003. After its selection, it was propagated asexually by stolons in a nursery located in San Joaquin County, California and extensively tested over several years in Ventura County, California.
Tests & Trials: Trials for 'Marvel' were conducted in field plots located in Sainte-Anne-des-Plaines, Québec, during the summer of 2012. Each plot was 1.20 metres wide and 15 cm high and covered an area of 22 square metres. The plots contained 100 plants which were spaced 0.35 metres in rows which were 120 metres long. There were 4 replications per variety which resulted in 1,350 plants per variety. For each variety, 4 plots of 100 plants were randomly selected for collecting data.
