«Nektar» -the new red variety wine grape aromatic high quality

Abstract

Context and purpose of the study – The multi-annual study of the International Genetic Bank of the Grape Vine has shown that red varieties are enough, but the red varieties that produce high-quality red wine are minimal. This paper presents is the create, the study and amplographic description the new red variety “Nektar”. The new red variety “Nektar” was created at the Athens Vineyard Institute in 2012.  

Material and methods – The variety created by crossing by the method of hybridization of the newly Greek variety “Makedonas” (“Ksinomauro” x “Cabernet Sauvignon”) with the newly Greek variety “Tihi” (“Augoulato” with the pollen mix of varieties Cabernet-Sauvignon and Grenache noir).

Results – The “Nektar” is is a new red grape variety wine-making quality aromatic. The duration of the variety from budburst to maturity is 136-145 days. The variety is very strong with large shoots growth (2.1 – 3.0 m). The growth of shoots is higherover 95 %. The average mass of cluster is 360 g and the yield are high, 15-20 t / ha. The “Nektar” grape variety is medium, spheric,middle density, the diameter 15 mm, with anaverage weight of 1,9 g and a blue-black color.The flower is hermaphrodite. The pollen is fertile.The quantity of seeds in berry is3-4. The skin is thick with high strength. The flesh isnone or very weak, with a special flavor of the variety, green paper. The content of sugar in must is greater than 24 %. The “Nektar” variety, based on its ampelographic and natural characteristics, is classified in the group of varieties convarietasponticaNeqr. It is distinguishedfrom by its high resistance to drought and fungal diseases compared to other varieties of Vitis vinifera L. The variety is intended for the production of high-quality red wines, and very aromatic juices. Can be used in the genetic improvement of vitis vinifera varieties as a qualitydonor

DNA and type of grain: which factor does better explain sensory differences of sessile and pedunculate oaks?

Sessile oak and pedunculate oak have shown several differences of interest for enological purposes. Tannic and aromatic composition among sessile oak or pedonculate oak has been well studied. Sessile oak is generally more aromatic than pedunculated, while the later is more tannic. This scientific point of view is rarely applied to classify oak in cooperages. Most coopers use the type of grain to distinguish wide and thin grain.

Geology and landscape as determining factors in microfields and development of the different Spanish appellations of origin

Dividing agrarian exploitations into microfields is a problem that influences the modern viticulture in a very important way. The aim of this work is the study of the influence of Geology and Geomorphology in agricultural structures

The French grapevine breeding program resdur: state of the art and perspectives

The French grapevine breeding program for durable resistance to downy and powdery mildew (INRAE-ResDur) was initiated more than 20 years ago to help reduce the heavy use of plant protection products and provide a durable mean to cope with a strong pathogen pressure. This program has now proved to be effective, with about ten new varieties already officially registered. However, there is still a lot to be done (1) to reduce the duration of each breeding cycle, (2) to diversify disease factors’ pyramiding and anticipate emerging diseases, (3) to work towards larger adoption of the new resistant varieties. New breeding schemes incorporating for example genomic prediction of breeding values are being evaluated to accelerate genetic gains, saving cost and time while handling complex traits.

Estimation of stomatal conductance and chlorophyll fluorescence in Croatian grapevine germplasm under water deficit    

Water deficit profoundly impacts the quality of grapes and results in considerable reductions in crop yield. First symptoms manifest with reduced stomatal conductance and transpiration, accompanied by the wilting of apical leaves and tendrils. So far, there is no available data on the water stress response in Croatian grapevine germplasm. Therefore, objective of this study was to determine influence of genotype and treatment on stomatal conductance (gsw), transpiration (E), electron transport rate (ETR), and quantum efficiency in light (PhiPS2).
