Originality coefficients for Rosa L. by quantitative traits of leaf and flower

Based on the use of methods of statistical analysis of the sample and determination of the coefficients of originality of Smirnov, quantitative features have been identified that differ in significant variation and have rare (original) manifestations. The analysis was carried out for 49 varieties of roses from the Tsytsin Main Moscow Botanical Garden of Academy of Sciences on 14 quantitative traitsof a leaf and a flower. The cultivars have been identified that differ in high originality in terms of a set of traits, as well as in some of the most important quantitative traits of a leaf and flower, such as Snowflake, Peer Gynt, Akito Blushing, Mainzer Fastnacht, Heidelberg, Troika. The Rotilia cultivar has received a high coefficient for a complex of traits and in particular for a flower. The most typical representatives are Mona Lisa (Floribunda group), Betty Boop (Floribunda), Krasnyy Krym (Floribunda), Botticelli (Floribunda), Ambassador (Hybrid Tea), Parsla (Hybrid Rugosa) The work was carried out according to the state order of the Tsytsin Main Moscow Botanical Garden of Academy of Sciences 18-118021490111-5
