“…Newly bred cultivars are tested worldwide annually to identify genotypes well adapted to regional conditions and breeders are interested in performance and stability of their cultivars over a range of environmental conditions. However, although Pritts and Luby [27] gave an excellent overview about useful stability indices for strawberry cultivar trials, knowledge about genotype adaptation and genotype×environment interactions are limited and only few evaluations have been made out in the near past in Europe on modern cultivars [8,12,19]. A better understanding how environmental constraints influence plant performance is important for breeding new genotypes adapted to north and south, but also for their adaption to the prospective global climatic changes.…”

The site effect of five locations from north (Stjørdal, Norway, 63 • 36 N) to south (Ancona, Italy, 43 • 31 N) was evaluated in strawberry regarding yield performance, fruit quality, length of fruit developing time from anthesis to harvest start and length of the harvest season. Cv. Elsanta was grown at all sites while cv. Korona was cultivated in north and central Europe and cv. Clery in central and south Europe. Yield was more affected by seasonal and growing conditions than by latitude. Anthesis was delayed as influenced by cultivar up to 58 days from south to north and was nearly maintained until harvest start. Duration of fruit development was negatively related to daily mean temperature and increased with higher latitude. 29-34 days were required from anthesis to harvest start for cv. Elsanta, 29-36 for cv. Korona and 27-38 for cv. Clery. Corresponding GDD values (growing degree days; 3 • C base temperature) were independent from latitude and accounted to 334-355 for cv. Elsanta, 301-385 for cv. Korona and 320-434 for cv. Clery. Daily mean temperature decreased about 2 • C from south to north during anthesis to harvest start which induced a calculated 5.2 days longer fruit development period in the north. From harvest start to harvest end, GDD values varied for all cultivars between 297-402 GDD showing no influence of the latitude. However, simple summing of GDD values do not correctly describe the time of fruit development (from anthesis to the ripe fruit) for the whole fruiting period of a plant. GDDs for individually tagged flowers increased notably from the first third to the last third of the developing period due to increasing temperature as the season proceeded. The fruit quality standards dry matter, soluble solids and titratable acidity were influenced by latitude giving northern sites in general the highest values. Fruits grown at the southern sites were redder compared to those of the north.

The goal of this study was to develop a cradle to farm gate life cycle inventory and assess the environmental impacts of strawberry production in four major strawberry producing states of the United States: California, Florida, North Carolina and Oregon, representing 99% of the United States strawberry production. Life cycle environmental impacts depend strongly on geographic location and production practices. Data for California and North Carolina strawberry production were collected in collaboration with agricultural economists from those states using the "LCA Extended Enterprise Budget" Excel sheet (version 4.11). Data for Florida strawberry production were collected from the state's existing enterprise budget (a detailed accounting of production costs and returns which estimates profitability of an enterprise). Data related to Oregon strawberry production were obtained through interviews with strawberry producers. OpenLCA software was used to conduct life cycle assessment for strawberry production. Missing unit processes for production of agricultural machinery, pesticides, fertilizers and materials were modeled based on existing literature. In order to better assess the sustainability of strawberry production, three metrics encompassing nitrogen productivity, phosphorous productivity and fossil energy productivity were introduced. Global warming potential for California, Florida, North Carolina and Oregon strawberry production was estimated to be 1.75, 2.50, 5.48 and 2.21 kg CO 2-eq per 1 kg of strawberry, respectively. The difference between LCA results was due to variation in yield and management practices which depend on geographic location. Plastics, fuels and fertilizers were the inputs with the highest contribution to environmental impact categories. California strawberry production scored the highest on three sustainability metrics mainly due to having the highest strawberry yield.
