Newly introduced strawberry genotypes for Nordic Baltic conditions

Abstract

Eight recently introduced strawberry genotypes 'Chambly', 'Clery', 'Darselect', 'Delia', 'Harmonie', 'Matis', 'Sallybright', 'Salsa' and 'Senga Sengana' (standard cultivar) were evaluated at the Polli Horticultural Research Centre of the Estonian University of Life Sciences, Institute of Agricultural and Environmental Sciences. Phenology, winter hardiness, strawberry blossom weevil (Anthonomus rubi) injury, yield, fruit weight, soluble solids, sugar, acid and ascorbic acid content of the fruit were determined. Genotypes more suited to the Estonian climate conditions are the winter hardy, late-yielding cultivars 'Salsa' and 'Harmonie'. 'Salsa' has a good, high quality yield with large attractive fruit. The fruit of 'Harmonie' contains much ascorbic acid, but the sugar-acid ratio is less balanced. Early genotypes 'Chambly', 'Clery', 'Darselect', 'Delia', 'Sallybright' and the late genotype 'Matis' have a lower yield than the standard cultivar 'Senga Sengana'.
