The vegetable marrow and pumpkin are valuable vegetable crops thanks to high food and dietary qualities of fruits. Russia is on the third place in the world on gross yield of these crops, but on productivity takes the 11th place among the European countries. The state register of breeding achievements permitted for utilization in the territory of the Russian Federation for 2016, contains 152 varieties and a hybrids of vegetable marrows and the 138 pumpkins. But there are not enough varieties of a wide area, there are practically no ultra early varieties, there are not enough pumpkin varieties with a bush habitus of plants. The collection of pumpkins and vegetable marrows which is a source of valuable genotypes for the solution of actual tasks of breeding contains 2641 accessions from 99 countries of the world and wins the first place in the number of accessions among world genebanks. The greatest part of a collection (more than 1500 accessions) is constituted by advanced varieties, the second part of a collection (more than one thousand accessions) – local forms of pumpkins. Not large collection, about 50 accessions, but quite significant for its scientific and breeding values consists of hybrids, self-pollinated lines and donors of valuable traits. As a result of long-term evaluation of breeding accessions the germplasm collection that includes sources of valuable traits has been created. Genetic collection of pumpkin includes accessions with such traits as resistance to a virus mosaic, a naked seeds, bush habitus plants, spaghetti like fruit, parthenocarpy.

This study was carried out in spring and summer crop rotation in film unheatedgreenhouse in condition of Transnistria. The parameters of phenotypic variability weredetermined during the continuous periods including: from shoots to plantlet maturing;from plantlets to flowering; from flowering to ripening F1 hybrids and their parental lines. Early and middle early functionally sterile (gene ps-2) and fertile lines were taken for the experiment. It was shown that duration of vegetative period varied insignificantly in lines and hybrids. Phenotypic variation in interphase periods was also insignificant;however, the second period was characterized by stronger variation. The lines phenotypicvariation in lines during the continuation of vegetative period and its compounded phases depended on the genotype, year of study and their interactions. On the phenotypic variability of continuation of the period from shoots to flowering sterile lines significantly was caused by the genotype, the variation of the period from flowering toripening was equally caused by genotype and year of the study, the variability of theperiod from shoots to ripening was affected by genotype. On the phenotypic variation ofthe continuation of the vegetation in fertile lines is influenced by the genotype and itsinteraction with year of study, on the variability of the period from shoots to floweringequally genotype and year of study and their interaction on the variability of the periodfrom to ripening the interaction of genotype and year of study. Inheritance of  continuation of vegetative period and its components, interphase periods, mainly had the character of a negative overdominance (heterosis for earliness). The nature of inheritance of the continuation of vegetation and interphase periods may vary depending on the year of the study; however, there remained its direction. A strong correlation between the continuation of the period from shoots to maturation and its components of the interphase periods. Between the continuations of individual interphase periods from shoots to flowering and from flowering to ripening correlation was insignificant, which indicated the independent nature of inheritance of these periods.

The characteristic of the new variety of Cucurbita ficifolia (Cucurbita ficifolia Bouche.), «In honor of Memory Tarakanov», is provided. The variety is mid ripening, the yield of marketable fruits is 16,0-22,0 t / ha. The fruits are transportable, tasting score - 4.5-4.6 points with a strong aroma of watermelon; keep marketable quality within 250-270 days after harvest. Intended use is fodder and universal.

Valeeva Zarya Tadzhievna – 80th Anniversary.

The new hybrids of largefruited pumpkin, Vega and Pervenets VNIISSOK F1, the large-fruited pumpkin varieties, Muscvichka, and zucchini cv. Kornishonniy are characterized.

The results of pre-sowing treatment of radish seeds aimed at increasing of seed production, yield and its productivity in protected area are presented. The density fractionation of radish seeds by gravity separator is recommended for improvement of planting material quality and increasing of utilization efficiency of frame area.

The purpose of the standard is the valuation of the indicators of quality of candied fruit watermelon, cooked in sugar syrup, dried and coated in granulated sugar intended for industrial processing and nutrition. This standard is developed for the first time in the Russian Federation.

The biological properties and cultivation technology of savoy cabbage are presented in the article. The ways of breeding of this crop in VNIISSOK, some varieties and hybrids are described. Up to 2016, the 9 varieties and the 11 hybrids of savoy cabbage were included in to the State Register of selective breeding results (plant variety). The bestknown cultivars of VNIISSOK’s breeding are the early maturing «Yubileynaya 2170» (vegetation season is 102-114 days) and the middle-late «Vertyu 1340» (130-150 days).

The paper presents the information about technical tools and software wide used for statistic calculations and detection of linkage disequilibrium marker/trait as well as association between traits/genes and molecular markers based on identification of linkage disequilibrium. It is briefly discussed the destination of main computer programs most wide used for genetic mapping and association marker/trait. It is given Internet web-sites for downloading of necessary software.

The description of a new determinant tomato variety for open field and greenhouse film with the original small dense fruit, keeping quite well its marketable qualities within 15-20 days after harvest in milk maturity phase is given. The fruits are rounded with sharp elongated spout. Fruits are good for fresh consumption, canning and pickling. Recommended for baby food and food for people with problems of the digestive system.
