Based on the collection and organization of Chinese quince (Chaenomeles) germplasm resources in Shandong Province, research on classification, evaluation and elite breeding of Chaenomeles germplasm resources was conducted. Based on the nutrient composition analysis of Chaenomeles germplasm resources in Shandong Province, extraction process research was carried out targeting the developmentally valuable and unique components of Chaenomeles. Based on a detailed investigation of Chaenomeles production and utilization, targeted preliminary research on Chaenomeles processing and utilization was conducted to address the limiting factors such as high organic acid content in its fruits and well-developed lignified fibers. Based on existing varieties and processing and utilization demands, targeted elite breeding of Chaenomeles was carried out. The main performance indicators achieved by this research are as follows: (1) Systematically collected the existing Chaenomeles germplasm resources in Shandong Province, and established 2 Chaenomeles variety germplasm repositories. (2) For the first time, a relatively complete and scientific classification of existing varieties was conducted using technologies including morphological methods, quantitative classification and molecular markers, and Chaenomeles with different excellent characteristics were categorized into groups such as ornamental cultivars, fruit-use cultivars, fruit-and-timber dual-purpose cultivars and bonsai cultivars. (3) Three new elite Chaenomeles speciosa cultivars suitable for processing were bred: 'Mengshan Qingxiu', 'Mengshan Cuilv' and 'Mengshan Jinxiu', with yields reaching 5146 kg, 4530 kg and 4813 kg respectively. A new light-peel Chaenomeles cultivar 'Yishikang' was bred, with a yield of 2900 kg. An ornamental and fragrant light-peel Chaenomeles cultivar 'Golden Apple' was bred, with a yield of 2300 kg. Through crossbreeding, seeds of 23 different hybrid combinations were preliminarily obtained. (4) Progress was made in Chaenomeles cutting propagation technology, which was applied to elite seedling production. (5) Successful analysis of Chaenomeles fruit components and extraction and utilization of active ingredients such as oleanolic acid were achieved, and products including Chaenomeles canned fruit, fresh Chaenomeles juice, Chaenomeles vinegar and Chaenomeles wine were developed. (6) The project applied for 12 national patents, of which 2 national invention patents have been authorized. 8 research papers were published in national core academic journals. (7) Two elite cultivars, 'Mengshan Qingxiu' and 'Yishikang', were bred, and 3 gold awards were obtained at the China Forest Products Expo.
