Abstract

Steady interest to pumpkin biology and breeding in Kazakhstan is confirmed by the former research.Cucurbita pepo L. is harvested throughout all the continents under different climate conditions up to65° northern latitude. For peoples of our and neighbouring countries as populations inhabiting the SilkRoad countries in general, pumpkin is one of key ingredients of sustenance. It serves as the bread doughadditive and is widely used in national cuisines in the Central Asian region and beyond. Especial significance of pumpkin-based nutrition is explained by its implication in diet food and baby food due to thepresence of carious form of carbohydrates, vitamins, organic acids and microelements. Abundance ofnutritional composition in association with low cellulose content allows to recommend this melon cropfor being included into the diet at diverse inflammation processes. Numerous medicinal applications ofpumpkin is associated with cholagogue, diuretic, appetizer, anti-obesity, anti-insomnic, would-healing,baby food, diet food, anthelminthic, anti-atherosclerotic, anti-aging, anti-eczemic, cosmetic treatmentand other effects. One of modern approaches in pumpkin phytoremediation is transgenic generationwith programmed set of associated bacteria. This offers further transgenes for their transfer to soils, contaminating with organic pollutants. Cucurbitaceae spp. may be involved in postponing the aging process.Recent studies demonstrate that zucchini (Cucurbita pepo subsp. pepo) is a seasonal vegetable with highnutritional and medical values. A number of useful properties of this fruit were attributed to bioactivecompounds. Earlier phylogenetic inter-relationships within the genus Cucurbita (pumpkins, squashes,and yellow-flowered gourds) were investigated by comparing wild and domesticated taxa. By screeningan intron region from the mitochondrial nad1 gene as a marker, taxonomic relationships in floweringplants have been clarified to show the route of domestication for the Cucurbita. Six or more independentdomestication steps aring from distinct wild ancestors have been determined. It was proposed that Cucurbita argyrosperma had been domesticated from a wild Mexican gourd, Cucurbita sororia, growing inthe Southwest Mexico, or the same region that had produced the maize. The wild ancestor of Cucurbitamoschata remains unclear. Nonetheless, the mtDNA data has indicated that the site of origin could belocated in lowland northern South America. The wild ancestor of domesticated C. pepo subsp. pepo remains unclear. However, it relates to C. pepo subsp. fraterna stemming out from Southern Mexico. Oneof targets for Kazakhstan is maintaining and characterizing domestic pumpkin germplasms, manufacturing the pumpkin seed oil and developing pharmaceuticals. So it is critical to study genetic power of thelocal accessions, expected and observed heterozygocity enhanced by intraspecious and inter-specioushybridization.Key words: Cucurbita pepo L., Cucurbitaceae, genetic diversity, genetic origin, squash, phytoremediation, biochemistry, medicine.
