高油量品种的培育和高额含油量品种的保持,在耕作过程中是油料作物选种和良种繁育的一个最重要的任务。同一品种向日葵的各株种子间,其脂肪含量的差别为10％左右,而在同一植株的种子间,其脂肪含量的差别能够达到50%。所以,在含油量方面选择种子,不可以采取所有植株上的全部种子(例如,整个花盘上的向日葵籽)而仅仅是选择其中个别的含油量最高的种子。我们根据子仁中各不同脂肪含量比重上的 The cultivation of high oil varieties and the maintenance of high oil content varieties are one of the most important tasks in seed selection and breeding of oilseeds during the cultivation process. The difference of fat content among the seeds of the same variety of sunflower is about 10%, while the difference of the fat content among the seeds of the same plant can reach 50%. So, when selecting seeds for oil content, you can not take all the seeds on all the plants (for example, the sunflower seeds on the entire faceplate) and just select one of the seeds that has the highest oil content. We are based on the proportion of different fat content in the kernel
