Variety used for comparison: 'Jewel'
Summary: The fruit bearing type of 'PS5298' is partially remontant while it is not remontant for 'Jewel'. The stolons of 'PS5298' have weak intensity of anthocyanin colouration while those of 'Jewel' have strong anthocyanin colouration. The terminal leaflet of 'PS5298' is much longer than wide whereas that of 'Jewel' ranges from equal in length to moderately longer in relation to the width. The margin of the terminal leaf of 'PS5298' is serrate to crenate while it is crenate for 'Jewel'. The inflorescence of 'PS5298' has a medium number of flowers and is positioned at the same level to above the foliage whereas that of 'Jewel' has many flowers and is positioned below the foliage. The arrangement of the petals in the flower is not touching to touching for 'PS5298' while it is overlapping for 'Jewel'. The fruit of 'PS5298' is lighter red with a larger fruit cavity than those of 'Jewel'. The achenes of 'PS5298' are positioned level with the fruit surface, while those of 'Jewel', are positioned above the fruit surface. The fruit of 'PS5298' begins to ripen earlier than that of 'Jewel'.

Origin & Breeding History: 'PS5298' is the result of a controlled cross in 1997 between variety 'PS-592' and variety 'Aromas' conducted in Santa Cruz, California, USA. Seedlings resulting from this cross were propagated using stolons in a nursery located in Siskiyou County, California, USA. 'PS5298' was subsequently selected in 1999 from a controlled breeding plot in Salinas, California. After its selection, it was further propagated asexually using stolons in Siskiyou and San Joaquin Counties, California and extensively tested over several years in fruiting fields in Salinas, California.
Tests & Trials: Trials for 'PS5298' were conducted in field plots located in Sainte-Anne-des-Plaines, Québec, during the summer of 2012. 250 plants of each variety were planted in the middle section of a 120 metre row containing 1350 plants in total. The beds were 1.20 metres wide and 15 cm high. Each plot covered an area of 6.5 square metres and contained 30 plants which were spaced 0.35 metres in rows and spacing between rows was 2.7 metres. For each variety, 8 plots were planted and 4 plots of each variety were randomly selected for collecting data.
