Abstract:
This invention is a new and distinct grapevine variety named ‘IASMA ECO 1’ which is characterized by producing red oval berries in a loose bunch, which is much less sensitive to  Botrytis cinerea.

Description:
Latin name of the genus and species claimed:  Vitis vinifera  L. 
     Variety denomination: ‘IASMA ECO 1’. 
     CROSS REFERENCE TO RELATED APPLICATIONS 
     The present application is related to Community Plant Variety application 2012/2342, filed in the Community Plant Variety Office on Oct. 25, 2012, the entire contents of which are hereby incorporated by reference. 
     BACKGROUND OF THE INVENTION 
     Discussion of the Background 
     The new and distinct grapevine described and claimed herein originated from a hand pollinated cross of the Teroldego variety (seed parent) and the Lagrein variety (pollen parent), neither of which are protected by plant patent, plant variety protection certificate, or similar. The seeds were subsequently germinated and the resulting plants were planted in the field. The present variety of grapevine was selected as a single plant, and asexually propagated by hardwood cuttings. The resulting propagules were planted and were found to reproduce true-to-type through at least three generations of asexual reproduction, with the observations taking place from 2004 to 2010 in San Michele All&#39;Adige (TN)—Trentino Alto Adige—Italy (46° 11′ Lat. N., 11° 28′ Long. E., 235 s.l.m.). 
     SUMMARY OF THE INVENTION 
     To the inventor&#39;s knowledge, there are no varieties similar to the new variety; being a crossing result, they contain 50% of the genetic material of the seed parent and 50% of the genetic material of the pollen parent. 
     The present variety produces red berries. The color of the berries is red as in the parents. The variety has a loose bunch with oval berries, ripens 1 week later and is much less sensitive to  Botrytis cinerea.    
     The variety IASMA ECO 1 differs from the parents Teroldego and Lagrein in having hair without anthocyanin coloration in the apex. Hairs are not writhing and erect compared to parents that have high presence of hairs writhing and erect. 
     The spine of the sprout among the nodes and internodes is green (149A) in IASMA ECO1 variety, whereas in the parents it is instead green (150A) with red stripes (44B). Creeping hairs arc not present in the internodes in variety IASMA ECO 1 while in its parents creeping hairs are present (sparse) or absent on internodes. 
     The young leaf of the IASMA ECO 1 is green (136D) while that of the parents is NN155C with a high density of creeping hairs, while IASMA ECO 1 has an average density of them. 
     The mature leaf variety IASMA ECO 1 has 5 V-shaped lobes, while the parents have only three lobes with a revolute profile. 
     The teeth are straight and medium-sized in IASMA ECO 1, while those of Teroldego are convex, and in Lagrein they are concave and straight and short. The petiole sinus is Brace shaped, slightly open in variety IASMA ECO 1 while in Teroldego it is open V-shaped and U-shaped open in Lagrein. The base of the sinus is V-shaped in the parent varieties, while in IASMA ECO 1 it is U-shaped. The density of prostrate hairs on the ribs is high in the parents and medium in the variety IASMA ECO 1. 
     The section of woody shot is circular in Teroldego and Lagrein, while in IASMA ECO 1 it is elliptic. 
     The first inflorescence in IASMA ECO 1 is on the second node. The basal bud (1-3) fertility is very high, while the first inflorescence of Lagrein is on 3th and 4th node, with medium fertility of the buds; and in Teroldego the first inflorescence is on 5th internode with very low fertility. The number of inflorescences per shoot is 1.1 to 2.1 in parents and 2.1 to 3 in the variety IASMA ECO 1. 
     The first inflorescence of IASMA ECO 1 is about 15 cm long, and the date of full bloom is generally around June 10, while Lagrein has 15 cm inflorescence, and a date of full bloom in 7th June. The first inflorescence of Teroldego is 20 cm long and the date of full bloom is 7th June. 
     The cluster of IASMA ECO 1 is very long (&gt;24 cm), large (&gt;20 cm) and very loose, Teroldego shows a cluster of similar size but is very compact, while in Lagrein the bunches are compact and their length is between 16 and 24 cm and &lt;12 cm broad. 
     The IASMA ECO 1 berry is elliptic, narrow (&lt;13 mm) with the hilum barely visible. The flesh is slightly firm, and the length of pedicel is medium. In Teroldego and Lagrein the berry width is 13-18 mm, the hilum is visible, the pulp is firm, and the pedicel short. 
     The vesting period of IASMA ECO 1 is later than that of the parents.

     FINDINGS OK MOLECULAR INVESTIGATIONS 
     DNA was extracted from young leaves of different accessions for each variety by using the Doyle and Doyle extraction method (1990) as modified by Grando et al. (2003). Molecular markers were obtained by analyzing DNA specimens at the 9 microsatellite loci specified by the European projects named Gen-Res81 and Grape-Gen06 for vine variety characterization and at locus VMC1B11 (Vitis Microsatellite Consortium). In particular, the primers and amplification conditions described by Thomas and Scott (1993) for locus VVS2, Bowers et al. (1996) for loci VVMD5 and VVMD7, Bowers et al. (1999) for loci VVMD25, VVMD27, VVMD28 and VVMD32 and Sefc et al. (1999) for loci VrZAG62 and VrZAG79 were applied. PCR products were separated and analysed with the Genetic Analyzer ABI3130 and the GeneMapper® v4.0 software.

     BEHAVIOUR IN VEGETATIVE MULTIPLICATION 
     Grafted vine affinity with the most popular holders—good. 
     CULTIVATION CHARACTERISTICS AND SUITABILITY 
     The present invention vine variety shows good vigour with early sprouting stage, with blue-black, long, elliptic berry with medium thickness skin. The bunch is long, winged, conical and straggly. It has an abundant yield and is highly resistant to  Botrytis . Its late physiological maturity occurs in the third or fourth stage; it shows an excellent capacity to accumulate sugars while preserving medium-high acidity values. It can perfectly stand winter cold and shows a good resistance to downy mildew and powdery mildew. It prefers quite fertile hilly soils, but it perfectly copes with less fertile soils. 
     USE 
     The present invention vine variety is suited to produce both young and medium aged red wines. Young wines have a fruity taste (wild fruit and morello cherry). When slightly aged, spicy flavours become more accentuated; it shows a good acidic strength, also in case of small crops and particularly warm vintage years. The wines obtained from this vine variety show an excellent and deep ruby colour, good body, medium-high alcohol content, good texture and medium acidic strength. It is suitable to produce both young and medium-aged wines; maturing in wood and ageing create a more austere character, which is typical of noble red wines, with more spicy flavours that recall tealeaves. It can also be successfully used to cut other wines.
