ECOLOGICAL AND BIOLOGICAL FEATURES OF GROWING OF OWN-ROOT PLANTING MATERIAL OF FEIJOA

abstract 0681104032 issue 68 pp. 357 – 366 28.04.2011 ru 1654
The results of breeding of lignified cuttings of varieties and forms of Feijoa in the humid subtropical of Russia are presented. Lignified cuttings cut from the top and bottom were covered with uterine of root-own plant varieties of "Superba", "8-10""0-01"and "D-1" and placed on the beds with different substrates: tea soil; peat + sand, perlite. It is established, that the lignified cuttings from the bottom of the overgrown Feijoa variety “Superba” were better rooted in the "tea soil," from the top of the shoots - on the substrate peat + sand. Lignified cuttings of all forms and types of plants studied rooted worse in perlite

RESULTS OF FEIJOA HYBRIDIZATION IN THE HUMID SUBTROPICS OF KRASNODAR REGION

abstract 1311707051 issue 131 pp. 595 – 603 29.09.2017 ru 196
Feijoa crop is valuable due to the complex of useful traits (high frost resistance, big yield, ornamental value and long profitable period). These fruits have delicate flavor, nutritional and dietary properties. The fruits are juicy with a pleasant, gentle, refreshing sweet and sour taste, specific strawberry-pineapple flavor and contain significant quantities of important substances for the human body. Pectin (up to 2.5%), sugars (6-14%), proteins, vitamins, organic acids, mineral salts, etc. are among them. However, the challenge of its cultivation is the lack of cultivars and plantations are represented by a mixture of hybrids originated from free pollination, and characterized by a great variety in biological and morphological traits, differing not only in yield, but in size, shape and yield period. In this connection, the breeders faced the objective to create new cultivars of feijoa, using classical and modern breeding methods and available genetic resources for commercial gardening and production. Development of the core hybrid diversity material and selection of promising forms are the most important stages of the breeding process, providing success of further breeding programs. The breeding of varieties and forms for crossings was carried out according to the principle of combining the desirable traits of the obtained offspring. There are direct and reverse crosses in six combinations ('Dachnaya' x 'Superba', 'September' x 'Superba', 'Dagomysskaya' x 'Superba', 'Superba' x 'Dachnaya', 'Superba' x 'September', Superba ; X 'Dachnaya'). The viability of the pollen was evaluated prior to pollination, by germination on a nutrient medium - 1% agar-agar + 15% sucrose. The degree of fertility varied year by year: in 2015 - 60-62%, and in 2016 - 68-77-88%. The best crossing combinations were established 'September' x 'Superba' and the 'Superba' x 'Dagomyskaya for the creation of the hybrid genepool of Feijoa sellowiana. A high percentage of germination of the feijoa seeds was noted in combinations of 'Dagomyskaya' x 'Superba' (74%) and 'Superba' x 'Dagomysskaya' (70%).
