Cucurbita crops are among the most valuable and widely cultivated vegetable crops in global agriculture. Cucurbit seed oil meets the requirements of functional nutrition; it is material for the food industry and medicines based on natural ingredients. The present research was aimed at studying features of the biochemical composition of oil in seeds of the main cultivated Cucurbita L. species from the collection of the N.I. Vavilov Institute (VIR) grown in the conditions of the Astrakhan Experiment Station (AES) of VIR. The oil content in seeds of Cucurbita L. species varied from 40 to 49.7%. Over 80% of the fatty acids (FA) composition (FAC) was represented by oleic (13.6–49.6) and linoleic (33.5–69.3%) acids. The accessions of Cucurbita mixta Pang. were noted for high values of saturated FAs (palmitic and stearic), those of Cucurbita pepo var. melopepo (L.) Harz. of linoleic and linolenic, and those of Cucurbita pepo L. of oleic acid. The multiple factor analysis showed significant differences in FAC in accessions of C. pepo var. melopepo, Cucurbita maxima Duch. and C. pepo. The performed study allowed us to reveal FAC features in seeds of each Cucurbita species from the VIR collection and to identify the accessions with the best economically important indicators.

Powdery mildew (PM) is one of the most harmful diseases of cucurbits. Modern commercial varieties of squash Cucurbita pepo L. var. giraumonas Duch and patisson C. pepo var. melopepo L. received powdery mildew resistance genes from wild species. The Pm-0 resistance gene belongs to the linkage group 10; two CAPS markers were developed for its mapping [15]. The main intragenic marker NBS_S9_1495924/HaeIII is localized in the NBS-LRR region, the additional marker S9_1539675/MspI shows complete co-segregation with resistance to PM [15]. In the present study, these markers were used for molecular screening of an experimental set of squash and patisson samples (differ in resistance to powdery mildew) from the VIR gene bank collection and perspective breeding lines of the Krymsk Experiment Breeding Station branch of VIR. In total, 80 samples were investigated. Samples, carrying fragments of both CAPS markers (17) and fragments of only one marker (31) were found. Presence of two markers of the Pm-0 gene (NBS_S9_1495924/HaeIII и S9_1539675/MspI) has the strong correlation with resistance to PM (r = 0.837). For three powdery mildew-resistant samples, which has demonstrated presence of both markers of the Pm-0 gene, additional analysis of individual plants was done. Resistant plants with Pm-0 gene markers were self-pollinated to create resistant lines. Thus, molecular screening allowed to preserve the valuable trait of resistance during maintaining of the squash collection samples.

Relevance One of the priority directions of selection is the creation of varieties that are most adapted to local conditions with high productivity. Methods The object of study – varieties and hybrids of pumpkin of three Botanical species: Cucurbita maxima, Cucurbita moschata and Cucurbita pepo. The purpose of the work is the creation and introduction into production of high-yielding varieties of pumpkin with high quality fruits, resistant to bio-and abiotic conditions of the lower Volga region. Research objectives: the study of varietal diversity and identification of genetic sources adapted to the conditions of the region; artificial hybridization, evaluation of the obtained source material on the main economic and valuable features, selection of the best hybrid combinations and testing them in comparison with the best zoned varieties. Results The collection identified genetic sources of productivity: Chino, Sviten, Kham, Creen Warted Habbard, Zukat, Arina, Madam; the quality of the fruit: Sorme poire, Burgess Buttercup Wintes, Malishka, Duchess, Konfetka. Using the selected genetic sources in crossbreeding, new hybrid combinations were obtained, after testing of which the source material for breeding was formed in the hybrid nursery. The table shows the characteristics of the best hybrid populations of pumpkin species S. maxima, S. moschata. The best zoned varieties of table pumpkin created in recent years. Izyashnaya – medium-ripe, shortleaved, high-yielding (17.0-26.0 t/ha), with high quality fruits (12.0-16.0% solids); Izobilie – yield (18.0-25.0 t/ha), drought-resistant; Romantika – medium-ripe, resistant to powdery mildew, yielding (16.0-20.0 t/ha), high quality fruits (10.0-15.0% dry-VA, 60.4 mg% carotene).
