Sortimentul viticol – component al securităţii şi siguranţei alimentare

The degree of viticulture contribution in ensuring the food security and safety is considerably determined by the potential of genetic diversity of assortment. In the paper is presented the evolution of grapevine assortment in Republic of Moldova in terms of ecological-geographic origin of varieties, some agrobiologic characteristics. To ensure the branch sustainability in conditions of northern extremity of industrial viticulture, the concept of genetic improvement of assortment is oriented at creation of varieties, inclusive seedless with multiple biological resistance. In conditions of climatic and socio- economic challenges, in order to ensuring food security, we note as necessary the development and implementation of programs for exploration, conservation and evaluation of genetic resources diversity - a basis for increasing the competitiveness and resistance of varieties. Through the intelligent correlation of classical breeding methods with the molecular biology, but also on new methodological and instrumental basis under development, we see an opportunity of grapevine genome fructification

Evaluarea fertilităţii soiurilor noi apirene incluse în sortimentul viticol al Republicii Moldova

In the paper are presented the results of study of fertility of the new seedless varieties included in the grapevine assortment of the Republic of Moldova - Apiren roz timpuriu, Apiren alb, Apiren roz, Apiren Basarabean and Apiren negru de Grozeşti. The correlation between the main fertility elements (number of buds left after pruning, number of growing buds, total number of shoots, including fertile, number of formed grapes) was appreciated. In all cases a direct, very close correlation has been attested, especially for the varieties Apiren roz timpuriu and Apiren negru de Grozeşti. It is noted the advanced potential of all varieties for issuing shoots from multiannual wood, inclusive of fertile shoots

Evaluarea unor soiuri şi elite de perspectivă de viţă de vie în condiţiile genofondului IȘPHTA

In the paper are presented the agrobiological and ampelographic characteristics of the new varieties and elites, created and highlighted in the Republic of Moldova (National Institute of Vine and Wine, currently Scientific and Practical Institute for Horticulture and Food Technologies). Presented genotypes possess separately or in different combinations the characteristics necessary for a sustainable, competitive vitiviniculture: quality, including a different degree of seedlessness, productivity, increased or enhanced resistance to extreme fluctuations of temperature (in winter and in summer), to cryptogamic diseases, diverse use, long-term storage, transportability. The diversity of presented characters and properties is a valuable potential for completing existing assortment; servesas the basis for the development of organic production and as a strategic pre-breeding fund in future breeding programs
