水稻、玉米,大麦和谷子等作物籽粒淀粉的糯性在籽粒碾碎煮成粥饭或做成食用糕点时才能表现出来。在东亚地区发现保存的上述作物的糯性种质具有突变遗传的特征。糯性种质进入东亚较迟,因而从培养性和营养繁殖角度检测出突变体是极为困难的,并在没有利用价值的作物种质中亦不能发现糯性。糯性的遗传特征是其作为贮藏淀粉的结构成分时,通常使25%左右的直链淀粉缺失。在作物中不良突变体易于诱发,因而糯性这一遗传特征未被认识。用标记法对玉米进行遗传分析,将蜡状外表称为蜡质(WX)。水稻的粘性虽然等同于糯性 The waxy nature of kernels such as rice, corn, barley and millet can only be demonstrated when the kernels are crushed and cooked into congee or edible pastries. The waxy germplasm of the above preserved crops found in East Asia is characterized by a mutation inheritance. Waxy germplasm enters East Asia later, so it is extremely difficult to detect mutants from the perspective of culture and vegetative reproduction, and waxyness can not be found in the non-exploitable crop germplasm. Waxy genetic characteristics are stored starch as a structural component, usually about 25% of amylose is missing. Poor mutants are easily induced in crops, and the genetic character of waxiness is not known. Genetic analysis of the maize using marker method, the waxy appearance as wax (WX). Although the viscosity of rice is equivalent to waxy
