自从1964年印度古哈(Guha)等人培养毛叶曼陀罗(Datura innxia)的花药得到来源于花粉的单倍体植株以来〔1〕,培养花药以获得单倍体植株的方法被人们在各种作物上进行了广泛的试验。目前成功的植物已不下几十种〔2〕。甜菜是我国的重要糖料作物之一,为异交作物,且两年一代。在甜菜的杂交或杂种优势利用育种工作中,如能应用花药培养方法获得单倍体植株,经染色体加倍后获得各种纯系,对于缩短育种年限、加速甜
Since the cultivation of anthers of Datura innxia by Guha et al. In India in 1964 to obtain pollen-derived haploid plants [1], the method of culturing anthers to obtain haploid plants has been studied by A wide range of tests have been conducted on various crops. The successful plants no fewer than dozens of 〔2〕. Beets are one of the most important sugar crops in China, being out-of-the-box crops, and two generations. In the breeding of beet hybrids or heterosis breeding work, such as the application of anther culture method can be obtained haploid plants, obtained by doubling the chromosomes of pure lines, shorten the breeding time, accelerate the sweet
