What are the apple varieties?

There are several ways to divide apple varieties:

(1) According to the development period of the fruit to divide the development period of the fruit, that is, the number of days from the time of blossom fall to fruit ripening. This can be divided into early maturing varieties (<90 days, ripening before mid-July in south-central Hebei Province), early maturing varieties (90 to 120 days, ripening in south-central Hebei Province in mid-July to early August), medium-ripening varieties (120 to 150 days, ripening in south-central Hebei Province in mid-August to early September), medium-late ripening varieties (150 to 180 days, ripening in south-central Hebei Province in mid-September to October), late-ripening varieties (150 to 180 days, ripening in south-central Hebei Province in mid-September to October), and late-ripening varieties (120 to 150 days, ripening in mid-September to early September). (150 to 180 days, ripening in mid-September to early October in south-central Hebei Province), late-maturing varieties (>180 days, ripening after mid-October in south-central Hebei Province). (2) According to the color of the fruit at maturity can be divided into yellow varieties, green varieties and red varieties. Yellow varieties such as Wanglin, Golden Crown, Golden Label, Golden Halo and so on. Green varieties such as Australian green apple, India, etc.. Red varieties such as Fuji system, Marshal system and other varieties, Fuji system varieties according to the coloring type is divided into piece of red type (also known as Type I, such as Huimin short branch, smoke rich No. 2, red king will be, etc.) and strip red type (also known as Type Ⅱ, such as Fukushima, smoke rich No. 3, etc.) two kinds. (3) Divided by fruit size, apples are divided into nine categories according to the average fruit weight per fruit, i.e., very small (less than 25 grams), very small (25.1-50 grams), small (50.1-80 grams), small (80.1-110 grams), small (80.1-110 grams), medium (110.1-150 grams), large (150.1-180 grams), large (180.1-200 grams), large (200.1-200 grams), great (more than 250 grams), great (more than 250 grams), great (more than 250 grams), and very large (more than 250 grams). 250 grams), very large (more than 250 grams). (4) based on the number of chromosomes can be divided into diploid, triploid, tetraploid varieties, the vast majority of varieties of apples belong to the diploid, triploid varieties of Jonagold, Dipper, Lu Ao, etc., more than four chromosomes of the varieties are extremely rare. (5) According to the origin of the division can be divided into Fuji, Marshal Department, Jonagold Department, Gala Department, Golden Crown Department and so on. (6) According to the plant morphological characteristics can be divided into ordinary and short-branching varieties. Production application of the main short branch type varieties are marshal system of As, Russian dwarf 2, dwarf fresh, new red star, first red, super red, red, red, etc., the Golden Crown system of gold dwarf, yellow dwarf, Stark gold dwarf, etc., the White Dragon system of smoke green, etc., the Fuji system of Fukushima short branch, Miyazaki short branch, Lizumi short rich, smoky rich No. 6, etc..
