The results of comprehensive assessment of the collection samples of carrot are presented. Such traits as a resistance to carrot psylla and carrot fly, high yield, earlyripeness, high content of carotene were evaluated. The carrot varieties total resistant to psylla were not found. The genotypes with combination of such traits as a mild tolerance to pests, stable productivity and fruits quality are recommended as the initial breeding material for development of new varieties and hybrids of carrot.

The collection of vegetable bean varieties was screened for duration of vegetative and interstage periods. The initial breeding material as a source of early-ripeness was selected.

Results of X-Ray diffraction analysis of inner structure of seeds of green vegetable crops are shown. The advantage of this method over conventional analysis is the informative value, safe-keeping and integrity of tested seeds.

The results of evaluation of phenotypic individual variation of four cultivars (Nantskaya4, Moskovskaya zimnjaya A- 515, Marlinka, and Minor) and two hybrids (Mars F1, Gribovchanin F1) of carrot are presented. The genotype-dependence of variability of such traits as «diameter and high of leaves rosette», «leaves number», «length and width of leaf blade», «length and thickness of petiole», «length, diameter, and weight of roots» are shown. Utilization of data of phenotypic variability of studied traits for development of variety technologies of carrot is recommended. The insufficient informativeness of the coefficient of variability for estimation and selection of carrot forms for adaptivity is discussed.

Micefit is a product developed based on mycorrhizal fungi extracted from roots of swamp ledum. For ecological purposes the Micefit is used for final stage of cleaning of contaminated and polluted land at seed sowing and seedling plating. The effect of growth regulator Micefit on seeds of garden radish depending on different concentrations and exposures. The dependence of garden radish yield on time of treatment and concentration is shown.

The efficiency of bacterial products Mizorin and PG-5 for treatment of seeds and seedlings roots of tomato cv. Novichok was studied. The positive effect of these biological products on productivity and disease resistance of tomato was revealed. The most effective was Mizorin when both treatments were applied. Biological efficiency was 46% and 38% against Septoria disease and Phytophtora, respectively. The yield of tomato increased (0.4 – 3.3 t/ha) when Mizorin was applied.

The most abundant weed plants in fields of carrot are represented. There are annual, perennial, cereal, and dicot plants. The modern herbicides certified in Russia are classified depending on the group of weeds. The rules of application of herbicides are presented.

As a result of long-term study and several rounds of selection, the new variety of eugenol type of basil «Zhemchuzhina Podmoscovya» was developed for the Central Region of Russia. This variety was included in the State Register of selection achievements.

12 samples of carrot were analyzed for biochemical components in roots. 5 genotypes with high content of vitamin C, β-carotene, and total sugar were selected as genetic sources of high biochemical components.

The estimation of the new approach of obtaining of potential yield of common varieties and new breeding samples of potato growing on row- boxes of the new technology of the company «Sedek» was done. The use of the complex of agricultural practices, such as healthy initial material, high soil fertility, seed vernalization, early planting, application of covering materials, and watering, are allowed to get yields of potato at the level of 100 t/ha.
