Summary: A new strawberry cultivar ‘Tochigi i37 go’ was developed by the Tochigi Strawberry Research Center (Tochigi Prefectural Agricultural Experiment Station) in 2018. To enhance the characteristic variations of strawberry in Tochigi prefecture, the new cultivar was derived from a cross between ‘Tochigi 32 go’ and ‘09-48-5’ in 2012. ‘Tochigi 32 go’ was a breeding line with an early beginning of harvest time and a great yield. ‘09-48-5’ was a breeding line, which was resistant to Fusarium wilt. The number of runners of ‘Tochigi i37 go’ was relatively great. The plant’s vigor remained quite strong even in winter. Each inflorescence had eight to ten flowers. The fruit was 20 g on average, cordate in shape, and glossy bright-red in color. The yield of the cultivar was by more 20% greater than that of ‘Tochiotome’. The sugar content of the cultivar was nearly equivalent to that of ‘Tochiotome’, whereas the acidity was smaller than that of ‘Tochiotome’, subsequently an excellent taste. The firmness of the cultivar was equivalent to that of ‘Tochiotome’. Similarly to ‘Asuka Wave’ , the cultivar was resistant to Fusarium wilt.
