The results showed that the cultivation site is chosen as per relevant standards that ef- fective accumulative temperature （≥5 ℃） is equal to or higher than 1 900 ~C within 110 d from sowing date. It is notable that a good choice of planting site is a guar- antee of the technology and to establish the method cultivating sunflowers with three generations per year is of great significance in terms of reducing breeding process of inbred lines and breeding costs. In addition to that, it provides refer- ences for rapid cultivation of multi-generation sunflowers and improving breeding effi- ciency.展开更多
