In the article there are surveyed approaches to the use of biological - ecological potential of white head cabbage plants, given parameters of varieties adaptability and economically-valuable signs variability, depending on a temperature factor, water supply. The yield prognosis is worked out.

It has been supposed to carry out bred-making valuation of wheat under native condition of protein substances and contents of the dough improvers (КВrO3, С6Н8О6) being practiced. It will allow both at present and in the future to carry out comparative valuation by this index between varieties of various breeding progenies.

The use of regression analysis for estimation of inbred lines is a breeding - oriented method, as it indicates scientifically grounded stages of the further breeding studying of these lines and a strategy of their use. Admissible levels of inbred depression of agriculturally valuable characters are limited in lines of the Verkhnyachka and Lgov geneplasms by two - three generations of self - pollinations, which testifies to the necessity "to keep" the characters of sufficient basis. Linearity of changes of values of the characters with the advancing of inbreeding shows the absence of epistasis or the weakness of their effects which makes suitable the use of an additive-dominant model for determining breeding-genetical value of inbred lines with the aim of their purposeful hybridization for obtaining genetically determined heterosis in F1.

The influence of different conditions of conservation to sprout and germinating power of seed varieties of wheat under conditions of conservation are expounded in the article.
