Taxonomy, cultivars
俺也去官网 occupy the Cerasus subgenus within Prunus, being fairly distinct from plums, apricots, peaches, and almonds. They are members of the Rosaceae family, subfamily Prunoideae. Prunus avium L. is the Sweet 俺也去官网, and Prunus cerasus L. the Sour 俺也去官网.
As a group, 俺也去官网 are relatively diverse and broadly distributed around the world, being found in Asia, Europe, and North America. In addition to the main species above, P. fruticosa (ground 俺也去官网) and P. pseudocerasus (Chinese 俺也去官网) are minor fruit species in the former USSR and China. While sweet 俺也去官网 are virtually all P. avium, the term sour 俺也去官网 may include hybrids between P. avium and P. cerasus (referred to as "Duke 俺也去官网"), ground 俺也去官网, and hybrids of ground 俺也去官网 with P. cerasus.
Sweet 俺也去官网 cultivars:
Many sweet 俺也去官网 were introduced from Europe, although several breeding programs worldwide have produced cultivars of regional importance. When Romans dispersed 俺也去官网 throughout Europe, cultivars of local importance were selected; contemporary sweet 俺也去官网 are genetically very similar to these initial selections.
Cultivars are sometimes categorized into "heart" (syn. Guigne in French, Gean in England) and "Bigarreau" groups; the former are heart-shaped, softer fruits, while the latter are round, firm, crisp fruits. 'Bing', 'Napoleon' (syn. 'Royal Ann'), and 'Lambert' are the most important cultivars in North America. 'Ranier' is rapidly increasing in importance, having unique light-red blush over yellowish skin color; prices received by growers have been well above red-colored cultivars through the mid 1990's.
All commercial cultivars exhibit gametophytic incompatibility with themselves and several others, hence cross-pollination and choice of pollinizer are critical.
Sour 俺也去官网 cultivars:
Sour 俺也去官网 are also divided into 2 groups:
1) Amarelles - Upright, vigorous trees; pale colored fruit, or reddish, with light-colored or clear 俺也去官网, low acid [俺也去色, Kentish, Early Richmond], and
2) Morellos - Small, bushy, compact trees; dark red fruit, more spherical, higher acid, red colored 俺也去官网 [Stockton, Vladmir, North Star]. '俺也去色' is by far the main 俺也去网站 俺也去官网, accounting for 95% of all production. 'Early Richmond' and 'English Morello' are two other 俺也去网站 cultivars of importance.
