“世界一”是日本1951年从“元帅”和“金冠”杂交后代中选出。1953年作为育种材料介绍,由于果实极大,品质又好,故称“世界一”。1975年通过中日友好往来引入天津市进行试栽。结果后,经连续4年的观察鉴定,初步认为是个比较好的品种。近几年,辽宁,吉林、北京,河北等省、市先后引种。 “World I” was selected by Japan in 1951 from the offspring of “Marshal” and “Golden Delicious” hybrids. Introduced as a breeding material in 1953, due to the great fruit and good quality, it is called “the world one.” In 1975 through the friendly exchanges between China and Japan introduced to Tianjin for trial planting. After the results, after four consecutive years of observation and identification, initially considered to be a better breed. In recent years, Liaoning, Jilin, Beijing, Hebei and other provinces and cities have introduced.
