糖甜菜自交系在甜菜育种中起重要作用。由于在甜菜自交系选育过程中经常发生因自交不亲和,从而使优良系号灭绝这种遗憾之事,所以,长期以来,国内外糖甜菜育种家们都对甜菜自交不结实或结实率低的原因做过各种各样的探讨,并提出了许多科学的合理的见解。特别是对糖甜菜自交不亲和性状的遗传因子对甜菜自交结实率的影响有过详细报道(郭德栋,1985)。另外,育种家们对如何克服自交不结实也有过许多研究。 Sugar beet inbred lines plays an important role in beet breeding. Because sugar beet inbred lines in the breeding process often occurs due to self-incompatibility, so that the extinction of the good system of this regrettable thing, so for a long time, sugar beet breeders at home and abroad are not self-fruiting beets Or the reason of the low seed setting, and put forward many scientific and reasonable opinions. In particular, genetic factors of sugar beet self-incompatibility of sugar beets self-seeding rate has been reported in detail (Guo Degong, 1985). In addition, breeders have also studied many ways to overcome their lack of self-fertility.
