Summary: The growth habit of the plants of 'DrisStrawNine' is semi-upright whereas it is upright for both reference varieties. The plants of 'DrisStrawNine' have sparse to medium density of foliage whereas those of 'San Juan' have dense foliage and 'Puget Reliance' have dense to very dense foliage. The plant vigour of 'DrisStrawNine' is medium whereas it is strong for 'San Juan' and strong to very strong for 'Puget Reliance'. The inflorescence of 'DrisStrawNine' is positioned beneath the foliage whereas it is above the foliage for 'San Juan'. The stolons on 'DrisStrawNine' are few whereas they are many on 'San Juan'. The blistering of the leaves of 'DrisStrawNine' is strong whereas it is medium on 'San Juan' and absent or weak on 'Puget Reliance'. The petiole of 'DrisStrawNine' is short whereas it is medium to long on 'San Juan' and long to very long on 'Puget Reliance'. The calyx of 'DrisStrawNine' is larger in diameter than the corolla whereas it is smaller than the corolla on both reference varieties. The fruit of 'DrisStrawNine' is small to medium size whereas it is large in 'San Juan' and large to very large in 'Puget Reliance'. The band without achenes on the fruit of 'DrisStrawNine' is absent or very narrow whereas it is narrow on 'San Juan' and narrow to medium width on 'Puget Reliance'.

Origin & Breeding History: 'DrisStrawNine' arose from the cross of the unnamed proprietary variety, '94J283' (female parent) by another unnamed proprietary variety, '112H25' (male parent) conducted in June 2003 in Monterey County, California, USA. In the summer of 2004, 'DrisStrawNine' was initially selected from the seedling population based on yield, compact and open plant structure, fruit quality and everbearing habit. It was asexually propagated at Driscoll Nursery in Monterey County, California and subsequently further propagated and tested from 2004 to 2008.
Tests & Trials: Trials for 'DrisStrawNine' were conducted in Chilliwack, British Columbia during the 2014 growing season. The plots were planted in the spring of 2013 in a randomized complete block design (RCBD). Each variety consisted of 3 replicates/variety with 5 plants per replicate (for a total of 15 plants of each variety). Plants were spaced approximately 30 centimetres between plants in the row and spaced approximately 2.5 metres apart between rows. Measured characteristics were based on 10 measurements.
