Abstract
Sweet cherry (Prunus avium L.) production has developed since the earliest plantings in 1970 in Los Antiguos (Argentina) and the latest in 1990 in Chile Chico (Chile). During the last few years, new cultivars have been introduced in the region, but there are no records about their phenology and fruit quality.
The aim of this study was to characterize nine sweet cherry cultivars (Bing, Van, Kordia, Lapins, Sunburst, Napolitana, Rainier, Newstar and Sweetheart) growing in these areas by phenological and fruit quality aspects such as weight, caliber, soluble solids content (SSC), firmness, titratable acidity (TA) and color (L*, C* and h*). Phenology was determined from first bloom to harvest.
For postharvest fruit quality determinations, three samples of 100 fruit of each cultivar were collected at harvest from commercial orchards (2 to 6 orchards per cultivar). Means were statistically analyzed with a GLM procedure and Tukey test.
Significant differences were found in all characteristics (p<0.05). The most promising cultivars for the region, due to their late ripening and fruit quality, were Sweetheart, Lapins, Kordia, Bing and Van. The first three varieties were harvested in mid-January, while Bing and Van were harvested in late December.
Firmness (Durofel index) was 87.3 for Sweetheart, 77.5 for Van, 75.4 for Lapins, 72.5 for Kordia and 70 for Bing. TA (% malic acid) was 0.66 for Bing, 0.58 for Kordia, 0.5 for Van, 0.48 for Sweetheart and 0.44 for Lapins. SSC (°Brix) was 21.0 for Sweetheart, 21.9 for Van, 20.0 for Kordia, 16.8 for Lapins and 15.5 for Bing.
