Using the measured length, width, weight and the calculated profile index data, the samplescan be divided in groups of fruit forms. The base of the fruit form groups were the works ofPriszter (1962) and Fintha and Szabó (2005). We classified the samples in the following groupsshowed in table 2.ConclusionsThe results of our experiments correspond to the data of similar studies in neighbour countries.Observing a small number of specimens, we found valuable types for further investigation likeSzinpetri 2 and Kács 1 with heavy fruits and outstanding flesh proportion, and Kisgyır 1 and 3with dark red colour and easy to core attributes. The possibility of finding valuable specimens ofcourse is higher when the sample amount is larger, and this increases the chance of finding andselecting several well-adapted local cultivars.References1.

The main task was thebreeding of cultivars with large berries, high productivity and different ripening time. Breedingresearch has been carried out in National Botanic Garden of Latvia since 1980. In the work, classicplant breeding, interspecific breeding and polyploidy breeding have been employed, and wildlingonberry clones were used. The rabbiteye blueberry cultivar ‘Salaspils Izturīgā’ was selectedfrom seedlings of open pollination of the cultivar ‘Tifblue’ in 1993 and the cultivar ‘Lielogu’ wasselected from the hybrid (‘Delite’ x ‘Woodart’) seedlings in 1995. From the hybrid (cranberrycultivar ‘Franklin’ x lingonberry) seedlings were selected the cultivar ‘Dižbrūklene’ in 1997, thecultivar ‘Salaspils Agrās’ in 1996 and the cultivar ‘Tīna’ in 2006. The lingonberry cultivar‘Salaspils Ražīgā’ origin of the wild lingonberry clone was selected as cultivar in 1993; the cultivar‘Rubīna Lāse’ was selected in 1988 from open pollination seedlings of the cultivar ‘SalaspilsRažīgā’, but the cultivar ‘Jūlija’ was selected in 1995 from open pollination seedlings of the clone‘Krasnojarska’.KopsavilkumsSelekcijas mērėis bija radīt Eša zileĦu Vaccinium ashei Reade, Americas lielogu dzērveĦu(Vaccinium macrocarpon Ait.) un brūkleĦu (Vaccinium vitis-idaea L.) šėirnes, kas būtu piemērotas<strong>Latvijas</strong> klimatiskajiem apstākĜiem un slimību izturīgas. Galvenie uzdevumi bija izveidot šėirnes arlielām ogām, ražīgas un ar dažādiem ienākšanās laikiem. Selekcija tika veikta NacionālajāBotāniskajā dārzā Latvijā kopš 1980. gada.
