玉米种子的胚形,是指玉米种胚部果皮的形态、面积的大小及其沿形状。而不是指玉米种子胚的内部构造。熟悉玉米种子的胚形,能帮助鉴别玉米杂交种及其亲本自交系的纯度,能确定玉米种的收获、贮藏及播种等环节的技术措施。玉米种子的胚形在遗传上具有相对稳定性,是玉米品种的主要特征之一。拿王米自交系来讲:玉米自交系是基因相对纯合一致群体。种子的胚形特征,在玉米自交系、杂交种
The embryo shape of corn seeds refers to the shape, size and shape along the shape of the peel of corn embryo. Rather than the internal structure of the corn seed embryo. Familiar with the embryo shape of maize seeds, can help identify the purity of maize hybrids and their parents inbred lines, to determine the technical measures of maize harvest, storage and sowing. The embryo shape of maize seeds is relatively genetically stable and is one of the main characteristics of maize varieties. Take Wang Mi inbred lines: Maize inbred lines are relatively homozygous homozygous groups. Seed embryo characteristics in maize inbreds, hybrids
