由卵细胞未经过受精而发育成有机体的生殖方式,称为孤雌生殖。近年来,美国、日本、苏联、加拿大及西欧各国都在各种作物中广泛研究;国内有些单位采用孤雌生殖育种技术已经培育出油菜、小麦和水稻等作物新品种(系)在生产上示范推广。目前诱导水稻孤雌生殖主要有理化处理或远缘杂交等方法,其中以化学诱导应用最多。许多单位曾研究过2.4-D,NAA,KT,GA,IAA,乙烯利、二甲亚砜(D.S)、
By the egg without fertilization and development into organism reproductive way, called parthenogenesis. In recent years, the United States, Japan, the Soviet Union, Canada and Western European countries have extensively studied various crops. Some domestic units have adopted parthenogenetic breeding techniques to breed new crop varieties (lines) such as rapeseed, wheat and rice for demonstration in production Promotion. At present, there are mainly methods for inducing parthenogenesis in rice, such as physiochemical treatment or distant hybridization, among which chemical induction is the most widely used method. Many units have studied 2.4-D, NAA, KT, GA, IAA, ethephon, dimethylsulfoxide (D.S.)
