(一)在米丘林生物學的领域內,无性杂种的獲得,是一件很大的成就,因为这工作不但向以染色体為遺传物質基礎的門德爾莫爾根遺传學提出了挑戰,而且在育種工作實踐上也有很大的意義,但是,我認為无性雜種的問題,目下在遺傳學上還是无能为力的,因為到現任為止,我們只有无性杂種事實獲得的報道,而還沒有獲得无性雜種的規律。因而无性雜交工作,毫无預見性與一定程度的把握。前人的試驗,經過重複,很難再得到相似的結果。用同一材料與方法獲得无性雜種的可能性,可以由十分之几,千分
(1) The acquisition of cloning in the field of Michurin biology is a great achievement, as it not only challenges Mendelian genetics based on chromosomes as genetic material , But it is also very useful in breeding practice. However, I think that the problem of cloning is genetically still powerless, because as of now, we have only reported the fact that cloned anecdotes have not yet been obtained Asexual hybrids of the law. So asexual work, unpredictable and a certain degree of grasp. Previous experiments, repeated, it is difficult to get a similar result. The possibility of obtaining asexual hybrids with the same material and method can range from a few tenths to a thousand
