Biology and genetics of grapevine mod. 2: ampelography and breeding
Code: G250TB
Teacher:  Attilio Scienza
Year: 
Term: 
CFU: 
CFU subdivision: Lectures: 4,5
Other: 0,5
Basic aims:  Unit 1: To give the specific knowledge of biology and physiology of the vine on the basis of those acquired during the courses of general biology and agronomy and preparatory course of growing techniques in viticulture.
Unit 2: To provide students with some knowledge of both theoretical and practical preparatory course of growing techniques in viticulture and enology.
Acquired skills:  Unit 1: Analytical knowledge of organography, phenology, physiology and ecophysiology of the vine to address basic study of viticulture.
Unit 2: Knowledge about the origin of the grown grapes, methods for their recognition, techniques for improvement of their quality and performance through clonal selection and crossing and how to address the varietal choices depending on soil and climatic conditions.
Course contents:  Genetics reminders of plants; The origin of varieties: wild grape and processes of domestication; Ampelography: history and prospects; Traditional and innovative techniques ampelografics; Varietal Cards; Genetic improvement for clonal mass selection, for cross for rootstocks, and for the quality of grape for resistance to biotic and abiotic stress; The bases of the interaction between genotype and environment, phenotypic stability and its assessment through zoning.
Program:  The course aims to provide students with some knowledge of both technical and scientific applications to be better used in his profession of winemaker, the genetic variability present in gen. Vitis, and with variety of wine as rootstocks. In particular, the course will focus some aspects of the origin of cultivated varieties, methods for their recognition, techniques to improve their production performance and quality through clonal selection and cross and how to address the choices of varieties depending on the conditions pedo-climatic. 1° CFU. Introduction of course. Review of basic genetics of plants. The origin of varieties: wild grape and processes of domestication. 2° CFU. Ampelography: History and Prospects. Morphological characteristics of traditional and innovative techniques. Cards variety. 3° CFU - Genetic improvement for mass selection and clonal. 4° CFU - Genetic improvement for crossbreeding. Genetic improvement of rootstocks. Genetic improvement for the quality of grapes. Breeding for resistance to biotic and abiotic stress. 5° CFU The interaction genotype x environment. The bases of the interaction, phenotypic stability and assessment of the interaction through zoning.
Prerequisites:  The experience of recent years has shown that students, coming from high quality wine schools (S. Michele a/A, Alba, Conegliano V.to) or from families of vinegrowers, have an fairly base background to be able to better understand the contents of the course. Unfortunately, the number of these students is small and therefore plays a fundamental value of the technical and practical Training witch is schedule in the second year of the Course.
Preparatory instructions:  The student should have an adequate knowledge of some fundamental concepts of formal genetics of biometrics, cytogenetics, molecular biology and general viticulture (morphology and physiology of the vine).
Learning materials:  Teaching and bibliographic materials handed by the teacher to the tutor of the course.
Other info:  By passing the exam the student as winemaker should be able to: -recognize the main varieties and rootstocks suitable for the area where he works; - value the quality and potential production of the main varieties, - identify the choices of combinations of grafting (grape varieties, clones, rootstocks) capable of improving the pedo-climatics environment where he operates- be able to evaluate a scientific publication dealing witch genetic improvement, obtained both with traditional and innovative techniques - be able to set up a comparison test with different clones and varieties with relative microvinifications – being able to make a vine and wine report on the results of their research works – to be able to present the outcome of their work by means of Personal Computers (modern audiovisual techniques).
