The results of the reproduction of the bird cherry ‘hybrid krasnolistnaya’ by seedingthe seeds from free pollination
Are provided the results of reproduction of the fruit and decorative cultivar (bird cherry ′Hybrid Krasnolistnaya′). Unlike the other 16 varieties and forms of bird cherry of Novosibirsk breeder V.S. Simagin, tested in the Botanical Garden of the Urals Dpt. of the Russian Academy of Sciences for 20 years, the ′Hybrid Krasnolistnaya′ as a fruit and decorative taxon deserves further distribution. The objectives of the research work included obtaining red-leaved forms of bird cherry trees of the first and second generationby free pollination, determination the interrelation of the red-leafed and green-leaf seedlingsin the posterity. Varieties and forms, capable for rapid reproduction, are considered economically valuable. ′Hybrid Krasnolistnaya′ proved to be difficult to root cuttings, thereforewere made experimental crops of red-leaf cherry with seeds.The method of work was to collect seeds from the tree of the parent variety ′Hybrid Krasnolistnaya′ and from the tree of its daughter form Polusibs №1. Pre-winter seeding of bird cherry stones was carried out in the greenhouse in September 2015-2016. Measurementsof the seedlingsheight with a red and green color of leaves were made in September 2016 (one-year-old) and 2017 (two-year-plan). Due to the difficult rooting of lignifiedcuttings of the red-leaf hybrid, it is possible the pre-winter sowing of its stones with the production of 50% of seedlings with an average height of over 60 cm at the age of two years with colored leaves. Due to the heterosis, partly are formed tall seedlings with large leaves, with a brighter, saturated red-brown color and withtaste of the fruitssuperior than the original variety taste (Polusibs № 1). By the seeding of seeds from free pollination, come out biotypes valuable in selective relation.In the third year of fruiting (2015) from the perspective Polysibs №1 were harvestedfruits, and the seeds were sown in the greenhouse (the seeds from the mother’s red-leaved bird cherry tree by selection of V.S. Simaginwere under control). The height of seedlings in both variants of the experiment had a very high level of variability, whichis associated with the genetic polymorphism of bird cherry.
