In the article, we discuss issues of morphological and physiological control over plants of winter wheat. As the object of the research, we have selected landraces - the population of winter wheat, which was grown on the territory of the Kuban region in the last century. The aim of this work was determination of the effect on the reproductive system of winter wheat varieties of factors such as conditions of cultivation and processing "Cecece 750" 1.5 l/ha D. V. crop retardant. To achieve this goal we have conducted a morphological analysis of the growth cone at the VI stage of organogenesis, which provide quantitative evaluation of potential future seed production of spike of winter wheat. To study the effect of the year of breeding on the reproductive system of winter wheat varieties the analysis of variance was calculated according to the scheme 3×7 factorial variability characteristic due to the influence of genotype (factor B), cultivation year (factor A), that is repeated in time is interpreted as the effect of the year conditions of cultivation. The influence of retardant on the reproductive system of winter wheat varieties was conducted using the analysis of variance on the above described scheme, 2×7, where the factor "A" is presented in two gradations (options, retardant treated and not treated), in this case, repeated for years was excluded as a factor. The result of researches indicates that the rate of realized productivity is variety-specific and can serve as a measure of the flexibility of the studied cultivars to different environmental conditions. The analysis of variance showed significant retardant effect on the realization of potential productivity in all variants of the crops of soft winter wheat. The comparison of the average general population indicates that the genetic potential of tall varieties may not manifest even in favorable for crop cultivation. The artificial reduction of plant height by inhibiting the growth of retardant is an effective way to identify high productivity of these genotypes as varieties of winter and Nemenchinskaya Old No. 346

In the production of seeds of sugar beet hybrids, based on cytoplasmic male sterility (CMS), we use single-fruited male sterile (MS) and ungrown fertile pollinator (Fp) plants as components of the cross. Sugar beet has a two-year development cycle. In the first year, root crops intended for growing seeds are formed, in the second year, a rosette of leaves grows from the vegetative roots of the root crop, and flowering stems grow from the generative buds. The article presents the planting method for seed production of MS of sugar beet hybrids under irrigation during summer thickened sowing. This method allows you to grow root crops-plugs with a yield factor of planting material 1: 6, 1: 7. We have also considered technological methods for growing root crops-plugs of the parent components of MS sugar beet hybrids on irrigation. The features of moisture supply and mineral nutrition systems were studied. The techniques of sowing technology and the formation of density of planting, care of crops, as well as methods for the protection, harvesting and storage of mother beets, contributing to the production of high-quality planting material, have been developed

The article presents the results of study of the reproductive capacity of landrace varieties of winter wheat on the example of the chief of the ear. Analysis of sales productivity was conducted by the method of F. M. Kuperman. We have also considered the relation of actual productivity number formed flowers on the 6th stage of ontogenesis

The article discusses the effect of additional spikelets in the variety of Bezostaya 1 on the realization of productivity of the examined plants. We traced the frequency of occurrence of multirov spikes and studied the effect of this phenomenon on the productivity and the main quantitative characteristics of the studied plants. The article demonstrates the structure distinction of productivity for abnormal and normal ears. Experience was one-way vegetation, planted in triplicate, time of experiment - 2013 - 2015 years. The study revealed that the most frequent was the emergence of 1-4 additional spikelets per spike. Some quantitative characters had a slight deviation, these include the number of spiked ledges on the kernek, spike length and plant height. To a large extent we increased the characteristic values such as the number of grains per ear, number of spikelets per spike, number of grains onto the ledge, head weight and the weight of grains spike. We significantly reduced weight of 1000 grains. It was revealed that more localized spikes were mostly in the middle, the most productive part of the ear. As a result, changes have affected not only the quantitative characteristics related to the productivity of the ear, but also its architectonic whole
