近四、五十年以来,已发现不少玉米胚乳的突变种,有些已投入商业生产,还有一些也有可能投入生产。本文摘要介绍玉米胚乳的突变型,它们目前的价值,和长远的意义,下月将发表的第二篇文章里,将探讨两种对养猪和养牛,特别有价值的胚乳突变:蜡质(Waxy)玉米,和不透明-2(Opaque-2)。这两篇文章里,涉及的玉米突变型,已改变玉米子粒的最大器官——胚乳。正常玉米的胚乳占籽粒全 Nearly four or five years ago, many mutant varieties of corn endosperm have been found, some of which have been put into commercial production, while others are also likely to be put into production. This paper presents an overview of the mutants of corn endosperm, their current value, and the long-term implications. The second article, to be published next month, will examine two particularly valuable endosperm mutations in pigs and cattle: waxy (Waxy) corn, and Opaque-2. The two maize mutants involved in these two articles have changed the endosperm, the largest organ of corn. Endosperm normal corn accounted for the whole grain
