| Abstract:
From 1999 to 2003, twenty-five red and white currant (R. rubrum L.) genotypes were tested at the Latvian Institute of Fruit Growing. The genotypes were evaluated for morphological traits, yield components, fruit quality, disease and pest resistance, and winter and spring frost hardiness. Multi-criteria analysis was used to assign an overall value to each genotype. Red currant cultivars ‘Rote Spätlese’, ‘Neimana Kirsu’, and ‘Varshevicha’, and white currants ‘Zitavia’ and ‘Werdavia’, which had high evaluations of yield components and good chemical composition, have the best breeding potential for processing. The red currants ‘Rote Spätlese’, ‘Rotet’, and ‘Varshevicha’, and white currant ‘Zitavia’, which were characterised by large berry weight and number of flowers per cluster, are the best potential parents for developing cultivars for fresh consumption. In total, six red currant cultivars – ‘Red Dutch’, ‘Neimana Kirsu’, ‘Rote Spätlese’, ‘Rotet’, ‘Rovada’, and ‘Varshevicha’, and five white currant cultivars – ‘Belaya Kuzmina’, ‘Cirvja Piets’, ‘White Dutch’, ‘Werdavia’, and ‘Zitavia’ were selected as the best parental breeding material in Latvia. ‘Rote Spätlese’, ‘Red Dutch’, ‘Neimana Kirsu’, ‘Varshevicha’, and ‘Werdavia’ were the most remarkable, because they each have more than five important traits. The Latvian white currant ‘Cirvja Piets’ and dark red ‘Neimana Kirsu’, and local forms of ‘Red Dutch’ and ‘White Dutch’ are recommended for the preservation in genetic resources collections and incorporation into breeding programs. | |
