Learning objectives
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.
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.

Syllabus
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.
