用超甜基因型(Sh_2)玉米和隐性三倍体直链淀粉基因(ae)、发暗胚乳基因(du)、糯质胚乳基因(wx)玉米杂交所得的杂交种,由于先天的种子质量差,在大量生产中受到限制。这种种子与普通玉米或普通甜玉米(Su)种子相比要轻、皱缩及种子活力低,并且会频繁地分离出不稳定的个体。本研究是指导超甜玉米种子在吸收期间代谢产物沥滤的测定及过度的沥滤是否与基因型及 Hybrids obtained by crossing sweet corn genotypes (Sh 2) with recessive triploid amylose genes (ae), du, waxy endosperm genes (wx) maize due to the inherent seed quality Poor, limited in mass production. The seeds are lighter, shrunken and have lower seed vigor than either normal or normal sweet corn seeds, and the unstable individuals are frequently separated. This study is to guide the supersweet corn seeds during the absorption of metabolites leaching and excessive leaching whether the genotype and
