Abstract:

In order to comprehensively summarize the apple breeding achievements in the past 70 years since the founding of the People’s Republic of China, the information on the parent composition, parent selection and characteristics of 273 apple cultivars (excluding rootstock) in China from 1951 to 2019 were collected and systematically analyzed, and the pedigree diagram of these cultivars was drawn. Among 273 apple cultivars, most were obtained by hybridization (145, 53.11%), followed by bud sports (111, 40.65%), seedling selection (15, 5.50%) and mutation (2, 0.73%). According to the skin color, the cultivars with red skin were the most (240, 87.91%), the number of green and yellow skin were 19 (6.96%) and 14 (5.13%), respectively. According to the average fruit mass, the percentages of big size (≥200 g), middle size (100-200 g) and small size (≥100 g) fruits were 57.14%, 35.53% and 7.73%, respectively. The percentages of the early, middle and late maturity were 24.54%, 32.97% and 42.49%, respectively. Among the 273 apple cultivars, 83 (30.40%) were long-storage, 78 (28.57%) cold-resistant, 34 (12.45%) spur-type, 8 (2.93%) columnar and 4 (1.47%) red-flesh cultivars. 262 apple cultivars with known parents were bred from 103 parents, including 3 local, 63 abroad and 37 derived cultivars. Pedigree analysis revealed that Fuji, Golden Delicious, Delicious and Gala were backbone parents used for apple breeding, with 104, 64, 36 and 24 cultivars, respectively. Hybridization and bud mutation were the main methods to apple breeding and the combinations with both parents from different geographical area or having great botanical characteristic difference always had strong heterosis. On the basis of these, the problems in apple breeding were analyzed, and the application of biotechnology in pedigree analysis was also prospected. This paper provided a useful reference for making the breeding plan and selecting parents of apple in the future.

Key words: apple, released variety, pedigree analysis, parental selection, backbone parents
