The results of introduction and selection of interspecific hybrid nectarine forms in the conditions of  Botanical Gardens of Dnepropetrovsky National University named after O. Gonchar have been given in the article. The perspectives of further use of selected nectarine genotypes in breeding work and nursery practice have been.

Changeability of low winter wheat sorts according to high-yielding properties and elements of productivity depending on years of growing has been investigated. Characteristics for effective selection of high quality. genotypes of winter wheat have been singled out.

Development and improvement of a female component of MS hybrids of sugar beet were carried out on the basis of the following methods: inereasing frequency of occurrence of sterility maintainers by means of preliminary saturation of the population with alleles of the x and z genes; the use, as a female form, of simple sterile hybrids from the crossing of sterile lines with unrelated O-types; and also the drawing in of complexes of valuable genes from materials of foreign origin.

Tere are discussed results of joint Bukovino-moldavian corn breeding programmer, as a result which are created two registered hybrids, one perspective, and new material for the further work.

The results of 39-year large-scale work on apple breeding for the improvement of fruit biochemical composition are discussed. The character of the inheritance of the content of sugar, titrate acids, ascorbic acid and P-active substances in fruit is shown. The brief descriptions of the new varieties with good flavor and harmonic combination of sugar and acidity are given. The prospects of the trend are shown.

The present state of genofond of the collection that includes 78 taxa supfamily Maloideae C. Web. (Rosaceae Juss.) in DNU Botanical Garden.

Giving regard to the main elements of Winter Wheat varieties assessment when selecting frost resistant plants and taking into account genetic potential of the parents, date of hybrids sowing and their assessment by the speed of spring vegetation, it is possible in the sense of successful breeding to derive the most steady genotypes by the specified characteristics starting from F1. hybrids.
