玉米籽粒重量的百分之八十以上是胚乳。玉米的许多重要经济学性状属胚乳性状。胚乳性状的遗传受3N 遗传结构的控制,而胚所发育的性状由2N 遗传结构来决定。长期以来人们用2N 的遗传模型研究着3N 的胚乳性状,而且在许多研究中误把当代植株与其所结种子当作同一世代进行遗传分析,这就给许多关于胚乳性状遗传规律的研究带来根本的偏差。普通玉米的蛋白质品质不佳。奥帕克一2(02)单隐性基因突变体可以大大改善玉米
More than eighty percent of the weight of the corn kernel is endosperm. Many of the important economic traits of corn are endosperm traits. The inheritance of endosperm traits is controlled by the 3N genetic structure, whereas the embryo developmental traits are determined by the 2N genetic structure. The genetic model of 3N has long been used to study the endosperm trait of 3N, and in many studies, the genetic analysis of contemporary plants and their seeds as the same generation has been mistakenly analyzed, giving rise to many fundamental studies on the genetic law of endosperm traits The deviation. Normal corn protein poor quality. Opaque-2 (02) single recessive mutant can greatly improve maize
