Carlos Muñoz Schick Ingeniero Agrónomo, M.S., Ph.D. Facultad de Ciencias Agronómicas Universidad de Chile Located in the SW of South America, occupies an area of 756.098 km2 (75 million ha). Extends from latitude 17º30’S to 56º30’S, for 4.326 km, which is equivalent to 1/10 of the Earth circumference, making Chile the larges country in the world, but is also the narrowest, with an average width of only 180 km, around parallel 70ºW. It is a mountainous country, flanked to the East by the Andes Range and to the West by a Costal Range, leaving a large Central Valley, where most of the agriculture take place. The total cultivated land amounts to 5,1 million ha; meadows, 11,2; introduced forest species, 1,0; and, native forest species, 5,6 million ha.

Between latitudes 27º and 43ºS, Mediterranean and Temperate Climates predominates. Precipitation occurs mainly in winter, increasing from N to S and from E to W. Because of this, many agricultural activities require irrigation. This area is generally free of polar winds, hail, tornadoes, excessive snow, etc., which is ideal for intensive agriculture. Back to my main topic: Of the more than 300.000 species of vascular plants on Earth, only about 300 have been domesticated. Less than 30 species constitute the food base of humanity. Only 12% of the plant families have contributed with domesticated species. Few plant families (Graminae, Leguminosae, Solanaceae, Rosaceae) provide the bulk of the species of agricultural interest. There are over 6.000 species of vascular plants in Chile. 85% of the species are native, and 50% of them are endemic. 21,3% of the vascular native flora has been reported as useful or, at least, with potential use.

Edmundo Acevedo / Paola Silva Cereals with drought resistance Cecilia Baginsky / Herman Silva R. Grain Legumes, pseudocereals of local origin Herman Silva Asencio Genomics Strategically located in the Southern hemisphere, allowing plant breeding in diverse environments. Ideally suited for counter-season breeding activities for Northern hemisphere locations, providing opportunities to test segregants twice a year. Research expertise in a variety of species, including fruit and vegetable crops, cereals, grain legumes, ornamentals, etc. Ample opportunities for domestication of native species. Expedited import and export procedures for plant material. Low incidence of pests and diseases. Clear rules and regulations for conventional and transgenic plant materials. Ample availability of irrigation water. Well trained and experienced scientists and technicians. Qualified labor force. Good correlation with some environments in the Northern Hemisphere, facilitating effective selection for important traits in many crops. Thanks for your attention .
