柑桔属的绝大多数栽培品种(除柚外)属于多胚性。用其作母本很难获得杂种苗,即使混有少量杂种苗也极难识别,要想通过杂交获得无核优良品种则更为困难。目前栽培的柑桔无核品种,多属雄性不育,虽能作母本,但又是多胚性。近年我们在广西恭城县城厢公社江贝大队果树专业队小河口果园中,发现一株十年生有育种价值的材料—“变异蕉柑”,其树高4.38米,较直立,树冠3.6×3.1(米~2),
The vast majority of citrus cultivars (except grapefruit) belong to the more embryogenic. It is very difficult to obtain hybrid seedlings by using it as a female parent, even if mixed with a few hybrid seedlings, it is more difficult to obtain good seedless varieties by crossing. Currently cultivated citrus non-nuclear species, mostly male sterile, although can be used as the female parent, but it is more embryogenic. In recent years, we found a 10-year-old breeding material “Variegated Banana Citrus”, which has a height of 4.38 meters and a height of 3.6 × 3.1 in the corral orchard of the Fruit Tree Specialty Team of Jiangbei Brigade of Chengxiang Commune in Gongcheng County, Guangxi.
