K-1 I.B. Dry Recent progress in understanding the genetics of pest and disease resistance in Vitis CSIRO Plant Industry, Waite Campus, Urrbrae, South Australia, Australia Corresponding author: ian.dry@csiro.au Grapevines are highly susceptible to a wide range of pests and microbial pathogens including insects, nematodes, fungi, oomycetes, bacteria, phytoplasmas, viruses and viroids. Historically, grape growers have relied heavily on the use of pesticides and fungicides, in combination with various management techniques, to minimise the impact of these pathogens. There is, however, increasing financial, regulatory and market pressure on grape growers to minimize the application of agrochemicals in the vineyard. An example of this is the recent proposal by the European Commission to ban the use by 2013 of a large number of agrochemicals in Europe which are routinely used for the control of grapevine fungal diseases. In the face of these increasing pressures, the development of new grapevine cultivars with improved “natural” genetic resistance to pathogens is a high priority. This review will summarize our current understanding of the genetic basis of resistance to plant pathogens and outline a number of different molecular strategies currently being used to develop pathogen resistant grapevine germplasm either by genetic transformation or marker-assisted breeding. This includes not only the mapping and cloning of dominant resistance genes from wild grapevine species but also the potential application of strategies which target “susceptibility” genes which predispose plants to infection by certain pathogens. 15 
K-2 Progress in grapevine breeding R. Eibach* and R. Töpfer Federal Research Centre for Cultivated Plants, Julius Kuehn Institute, Institute for Grapevine Breeding, Geilweilerhof, Siebeldingen, Germany *Corresponding author: rudolf.eibach@jki.bund.de Since the introduction of phylloxera and the mildew diseases from North America to Europe during the second part of the 19 th century, grape breeders around the world have been engaged in introducing into the gene pool of the European quality vines resistance traits existing in wild American and Asian species. Meanwhile these activities have led to remarkable success, resulting in cultivars with high wine quality and a high degree of resistance against downy mildew as well as powdery mildew, allowing a considerable reduction of plant protection. Nevertheless it can be stated that breeding progress in the past has had considerable limitations. Apart from the long generation cycle, the extensive evaluation necessary for a range of complex traits as well as the time-, labour- and space consuming cultivation of grapes are major restrictions. As a consequence, knowledge about the genetics and the inheritance of viticulturally important traits like resistance or quality characteristics was poor. However, substantial progress on these aspects has been achieved in recent years. Various research groups have generated genetic maps for various genetic backgrounds which allowed the identification of different loci carrying genes for crucial traits, especially resistance traits. The establishment of marker assisted selection (MAS) as a new tool for grapevine breeders offers plentiful possibilities for increasing breeding efficiency. It allows not only monitoring the segregation pattern of these resistance loci in the progeny but also identifying the genotypes with multiple resistance loci. This pyramiding by MAS should lead to a higher and an increased sustainability of the resistances. Similarly MAS allows a targeted selection of parents which have the potential for pyramiding resistance loci in their progeny. The establishment of elite breeding lines with homozygous resistance loci is another option which can only be realized by MAS. From such parents all offspring carry the resistance loci. Finally, MAS allows an accelerated introgression of desired traits from wild species into the gene pool of Vitis vinifera. The use of marker assisted selection for the target locus combined with a background selection for a high percentage of Vitis vinifera genome speeds up this process considerably. Summing up, it can be stated that the described newly available breeding tools and strategies will mark a paradigm shift from empirical to knowledgebased breeding. 16
