Abstract:

‘Yangguang 1’（Citrus reticulata Blanco），developed by a crossing of‘Hongmeiren’（Ehime Kashi 28）as seed parent with‘Haruka’as pollen parent，is a monoembryonic and sterile line showing seedless and male-aborted. It is vigorous with high fruit-setting rate. The leaves have smooth surface with acute apex. The fruits are smooth and high flat-round in shape. The pulp is light orange in colour，crispy and tender. Single fruit weights 240-270 g in weight with 13.0%-15.0% total soluble solids，0.65% titratable acidity and 435.0 mg · L^-1 Vitamin C. In Chongqing，it matures in late November. The fruits are tolerant to storage and transportation，but tend to be suffered from high fruit cracking rate in the open field，so this cultivar is suitable for cultivation in greenhouse facilities. With annual yield of 26 300-27 500 kg · hm^-2，the major production regions include the dry-hot river valleys of Yunnan，plain/hilly area in Sichuan and western Hunan region.
