【Abstract】 Tarocco Xinxi (Citrus sinensis Osbeck,) originated from a superior clone selected from offsprings of Tarocco nucellar,which was introduced from Italy.The fruit was medium-large in size (average weight of 194.9g) with shape of reverse-ovoid or short-ellipsoid.At maturity, both the rind and pulp color were deep red or purplish red.The pulp was tender and juicy ( juice content 55.25 %), with total soluble solids (TSS) of 11.68 %, and sugar of 9.08g, acidity of 0.95g and vitamin C of 60.16 mg/100mL juice, respectively. The fruit was seedless (mean 0.32 seeds per fruit) and its flavor had a nice aroma as rose.Tarocco Xinxi had heavy productivity (22 500～62 500 kg/ha) and the fruit quality was superior.And due to its late-matured time (late-January or early-February,avoiding the peak periods of the most citrus varieties ripening and selling in markets, and just meeting the Spring Festival),this variety had a significant economic benefits and higher potential in development.更多还原
