Resumen
This research started en 1996 with P. cerasus rootstocks grafted en 1997 with 16 cultivars that were trained in Tatura trellis in La Palma Experimental Station of Pontificia Universidad Católica de Valparaíso in Quillota, 5th region. The study covered each cultivar`s flowering and fruit phenology, vegetative and rizotron root growth, production, productive efficiency, fruit quality and fruit looses due to cracking and birds from 2000 to 2004 seasons. Winter chilling ranged between 407 and 505 hours bellow 7ºC and 497 to 711 PCU (ponderated chilling hours). Bloom and harvest dates were influenced by Hydrogen Cyanamid winter spraying and general production was very much influenced by each winter’s chilling accumulation. Vegetative growth reached its peak after fruit set while root growth after bloom and at initial leaf fall. The best productive cultivars were Brooks, Somerset, Lapins, Van, Newstar, Celeste and Rainier, while Bing, Early Burlat, Garnet, Marvin, Ruby, Sunburst, Starkrimson, Summit and Sylvia had a low to very low performance. Fruit quality was satisfactory for export quality standards and fruit losses due to cracking and birds were low in most cultivars FONDEF 2 FONDEF 40
