  10. Genetic markers enable plant breeders to begin their selection at the cell stage by looking for the gene responsible and checking at an early stage of cross - breeding, whether the desired gene has been inherited by the offspring plant, instead of having to go through the process of cross - pollination and then growing the offspring to see if they have inherited the desired characteristics, and if not, starting all over again.

    遺傳標記物的存在能夠使植物育種家在細胞階段就開始進行選種，所用的方法包括尋找相應的基因以及在雜交早期進行檢查看看想要的基因是否遺傳到子代植物，這樣就不需要經過復雜的傳統育種過程：雜交授粉種植子代觀察子代是否獲得想要的性狀如果子代沒有攜帶想要的性狀，再從頭開始
