Wulian Guoguang Apples

Wulian Guoguang Apples are a protected geographical indication agricultural product.

　　Wulian Guoguang Apples are a specialty of Wulian County, Rizhao City, Shandong Province. With a long history of apple cultivation in Wulian County, the small Guoguang apples are highly praised by industry experts for their dense flesh, crisp juiciness, well-balanced sweet and sour flavor, and rich aroma. Wulian Guoguang Apples are a nationally protected geographical indication agricultural product.

　　Rizhao’s Wulian County has a long history of apple cultivation. Since the 1960s and 1970s, the small Guoguang apple has been the dominant variety grown in the county. Thanks to their good coloration, firm texture, storability, well-balanced sweet and sour taste, and refreshing flavor, these apples have been very popular in major city markets such as Shanghai, Nanjing, Wuhan, and Harbin, and have even been exported to Russia. The saying “Yantai apples and Laiyang pears go without saying — Wulian Guoguang needs no introduction” has made the Wulian small Guoguang a renowned brand across Shandong.

　　In recent years, Wulian County has fully leveraged its unique geographical, climatic, soil, and ecological advantages to vigorously advance adjustments in its agricultural industrial structure. While introducing and cultivating new fruit tree varieties, the county has prioritized the consolidation and development of its promising native apple variety. The county government has supported the establishment of the “Wulian County Small Guoguang Apple Association,” uniting local “small Guoguang” growers for scaled development. This includes unified training and guidance, standardized orchard management, as well as coordinated harvesting, packaging, transportation, and storage. The county forestry bureau has carried out comprehensive development and intensive management of “small Guoguang” apples in accordance with international organic fruit production technical standards. They have experimented with and developed paper bag and micro-film bag Guoguang apples — these fruits are large, well-shaped, brightly colored, thin-skinned, crisp, and have a well-balanced sweet and sour taste. They are more favored by consumers than the larger, juicier but blander Fuji apples. In particular, the shift from previously crude wicker baskets to exquisitely designed high-end gift boxes for packaging has significantly increased the value of these once humble “ugly ducklings” that grew wild in the mountains, turning them into premium products on the market.

　　In 2013, the “Wulian Guoguang Apple” application submitted by the Wulian County Fruit Tree Station passed the review by the Agricultural Product Quality and Safety Center of the Ministry of Agriculture and expert evaluation, and was granted national geographical indication agricultural product registration and protection.
