Strawberry growing in Latvian has undergone some significant changes in last decade. After joining EU, very often strawberry planting material comes from nurseries in Netherlands, and some other countries. Other important change is growing popularity of the high tunnel use for strawberry production. It has been noted, that more often there are problems with the strawberry root rot in plantations where imported planting material used. In this study four different cultivars Honeoye, Darselect, Sonata and Rumba evaluated and scored according they health condition and affectedness by root rot, in FGV type tunnels. Differences between both tunnels were not statistically significant; however differences between cultivars were significant. Most affected by root rot was cv. Rumba, it had a highest number of plants with damaged root necks and root rot symptoms – stunting, partial dieback of plant. The healthiest was cv. Darselect, it had a lowest number of damaged plants and lowest damage scores among all tested cultivars. Other evaluated cultivars – Sonata and Honeoye were in between, with slightly worse results for cv. Sonata. It is necessary to continue evaluation of main causal agents, their spectre and dominating species.
