过去四五十年以来曾发现一些玉米胚乳突变种。在这些突变种中,有的已经应用于生产;有的表现有潜在价值。本文简要介绍几个玉米突变种,并讨论它们在当前生产上的作用和潜力。我们所涉及的玉米突变种是玉米子粒的最大部份一胚乳发生了变异。玉米的胚乳一般占总粒重的80—82％。虽有不少的玉米突变种已发现多年了,但直到最近才公认只有四个具有实用价值,这四个突变种是:“糖质1号(Sugary-1”、“绉缩2号(Shrunken-2)”、“高直链基因(amylose-extender genes)”和“腊质玉米(waxy maize)”。含“糖质1号”基因的玉米即一般所称的“糖玉米”,含“绉缩2号”基因的玉米又叫“高糖玉米”,人们
Some corn endosperm mutants have been found in the last four or five decades. Some of these mutations have been applied to production; others have potential value. This article briefly introduces several maize mutants and discusses their role and potential in current production. The maize mutants we are involved in are the largest part of the corn kernel - a variation of the endosperm. Corn endosperm generally accounts for 80-82% of the total weight. Although many maize mutants have been discovered for many years, it has not been recognized until recently that only four are of practical value. The four mutations are: Sugary-1, Shrunken -2 “,” amylose-extender genes “and” waxy maize. “Corn containing the” Sugar 1 “gene is what is commonly referred to as” sugar corn “and includes” 2 “gene of corn is also called” high-sugar corn, "people
