The effect of microbial growth regulator Mitsefit on sowing qualities of seeds and biometric parameters of pepper seedlings has been studied. The optimal effective concentration 10 ppm for utilization was determined.  This concentration  has the maximum positive effect on the germination energy; germination; early seedling growth; the rate of occurrence  of phenological stages; and biometric parameters of seedlings.  Pre6sowing seed  soaking in 10 ppm Mitsefit for 30 minutes increases  the vigor of seeds of pepper for 4 – 7.5%; the germination of seeds – for 6;5– 11%; and accelerates  the production of pepper seedlings for 3 days.

The results of investigation of the effectiveness of humic and bacterial growth regulators at direct sowing of broccoli in conditions of forest6steppe of Ukraine are given.

Analysis of morphological and physiological characters of amaranth varieties of VNIISSOK and Ecuador breeding grown under optimal conditions, as well as at low temperature and precipitation deficit showed a reduction in height, number of leaves and inflorescence length to different extents. It points to the different resistance of varieties to the unfavorable environmental factors.

The efficiency of root formation capacity of the bean hybrids in the conditions of forest,steppe  of the Ob region has been shown.

The sustainability of potato production in the Privolzhsky federal district was evaluated with the use of statistical methods. The effect of changes of yield and acreage on the production of the culture was evaluated. The stability of levels of dynamic series is estimated. The stability of production dynamics has been measured with the use of trend models.

Species composition of infected tomato seeds was determined: Fusarium oxysporum f. sp. lycopersіcі, Alternarіa solanі, Aspergіllus spp., Rhіzopus spp., Pseudomonas syringae pv. tomato. The effect of plant growth regulators, biological fungicides on sowing seeds quality has been studied. It was found that presowing treatment of seeds of cv. Kremenchugskiy and cv. Karasy increases the germination ability, vigor, and disease resistance. Spraying of tomato plants during vegetation has decreased the development of fungal diseases such as F. oxysporum f. sp. lycopersіcі (up to 4,8%), Aspergіllus spp. (up to 2,3 %), and Rhіzopus spp. (up to 5,8 %).

The number  of correlations  on vegetable peas depends on the length  of the growing period,  and the adaptive  capacity  of the samples.   In  F1    hybrids   manifestation   of  «t»  correlations   is increasingly close to their parents.

In the VIR collection there is a rich initial material, which can contribute to the intensification of breeding of leguminous of vegetable directions of our country, as well as an increase in speciesdiversity of cultures in this group.

The particularities of the changes of the morphological parameters of plants-regenerants of tomato hybrids F1 during prolonged cultivation in conditions of in vitro have been studied. The cultivation during 12 passages in hormoneless MS medium does not lead to somaclonal variants, but act to raise the increasing of coefficient of variability of plants-regenerants features.

The advantages of varieties of vegetable pea of VNIISSOK breeding have been shown. These varieties are suitable for canning, freezing, gardening, and for universal use.
