短枝型祝光品系是1973年选于江苏省丰县大沙河果园河东大队六座楼生产队14年生苹果生产园的一个自然突变体。大沙河果园计有祝光苹果1037.9亩,16489株。在大面积芽变选种中发现该母树树冠较矮小、紧凑,枝条粗短,叶厚色深,由于回缩修剪后的发枝亦较粗短,群众称之谓“平顶祝光”,经三年观察,确认非环境或栽培条件引起的变异。为了防止为周缘嵌合体而在以后生产中产生较多的退化芽,于1976年至1981年在苗圃进行了四次
Spur type wish light line was selected in 1973 in Fengxian County, Jiangsu Province, Dashahe Orchard Hedong Brigade six production team 14-year-old apple production park a natural mutant. Dashahe Orchard counties have 1037.9 acres of apple, 16489 strains. In large-scale germplasm selection found that the parent tree canopy is shorter, compact, thick branches short, thick leaves, trimmed after the retraction of the stubby also shorter, the masses called the “flat top wishful” After three years of observation, confirmation of non-environmental or cultural conditions caused by variation. In order to prevent the generation of more degenerated buds in the later production for the peripheral chimeras, nurseries were performed four times from 1976 to 1981
