在含有雄性不育的大豆【GLgcinl max)L)Merr】群体中,进行了三轮选择,旨在提高其籽粒含油百分比。将原始群体单株堆植,使可育株对不育株自然授粉。成熟时从杂交小区中选择含油百分比最高的雄性不育株。从这些不育株中再选出半姊妹家系(hlf sib fimi Lies)在温室中种植、收获;并从每一个半姊妹家系内选择含油百分比最高的个体。最后使所选的个体后裔在大田中自然杂交,从而开始新的轮回。 Three rounds of selection were performed in a population containing male-sterile soybean [Glycinin] L) Merr] with the aim of increasing their kernel oil percentage. Planting the original population into individual plants allows the fertile plants to naturally pollinate the sterile plants. Mature male sterile lines with the highest oil percentage are selected from the hybrid community. From these sterile plants, half of the sibling families (hlf sib fimi Lies) were selected for planting and harvesting in the greenhouse. Individuals with the highest oil percentage were selected from each of the half siblings. Finally, the selected individual descendants naturally hybridize in the field to start a new cycle.
