小粒种咖啡属自花授粉,实生后代遗传性状变异性小,但约有5%的自然变异率,因此,有紫叶型、柳叶型、厚叶型、高秆型、矮秆型等多种类型。实生后代性状较稳定,一般采用种子繁殖。小粒种咖啡品种类型有变种、种内杂交种、种间杂交种等多种类型。1.铁毕卡变种。该品种品质较好,原产于埃塞俄比亚及苏丹东南部,是现代所有红项品种的祖先。具有结果多、浆果大、成熟早、产量高、植株健 Small grains of coffee is self-pollination, the actual offspring of genetic variation of small, but about 5% of the natural mutation rate, therefore, purple, willow, thick leaves, tall stalk, dwarf type and more Kind of type The offspring of the offspring are more stable in character, and generally adopt seed multiplication. Small varieties of coffee varieties varieties, intraspecific hybrids, interspecific hybrids and other types. 1. Iron Pica variant. The breed is of better quality and is native to Ethiopia and southeastern Sudan and is the ancestor of all modern red breeds. With more results, large berries, mature early, high yield, plant health
