selection

In the conditions of the Moscow region, 10 samples of representatives of the genus Allium L. were studied, including: A. altaicum Pall., A. fi stulosum L., A. galanthum Kar. & Kir., A. oschaninii O. Fedtsch., A. pskemense B. Fedtsch from the section Cepa (Mill.) Prokh.; A. altyncolicum N. Friesen, A. ledebourianumSchult. & Schult. f., A. oliganthum Kar. & Kir., A. schoenoprasum L. from the section Schoenoprasum Dum.; A. komarovianum Vved. from the section Sacculiferum P. P. Gritz.

For 40 years the soil microflora of the Landscape Reserve «Osinsk Forest Summer House» (Perm region, Russia) was exposed to high concentrations of DDT. Soil from the blocks 11 and 32 were selected and used in the process of artificial selection of aerobic bacterial communities capable of degrading DDT. Selection was carried out in the laboratory in four stages. As a result, successional changes were recorded, accompanied by reduction in the number and diversity of morphological types of bacterial strains in microbial communities.

In article results of selection work on creation of new sorts of Chrysanthemum coreanum in Ufa botanical garden are explained, descriptions of 10 local new sorts are also provided. Their biometric parameters, decorative indexes and terms of blossoming are specified. The Chrysanthemum genus belong to Asteraceae family. Ch. coreanum – hybrid origin, a perennial plant with reinforced, more or less branched rhizome.

The aim of this study was to identify the effect of precursor (vapor, winter wheat) on the non-traditional selective grain quality parameter intensity of spring common wheat. The parameters include dough development time, dough stability, energy absorbed by dough while kneading and starch retrogradation coefficient. The data have been obtained using a Mixolab device.
