前言关于小麦早熟性的遗传规律,前人的研究分歧很大,大体上有以下三种看法:①认为早熟性为显性,F_1表现为同早亲或超早亲;②认为早熟性为不完全显性,F_1表现为介于双亲之间的中间型;③认为早熟性为隐性,F_1表现为同晚亲或超晚亲。在国内,1958年南京大学生物系遗传学教研组,1972、1973年安徽农学院农学系等单位做了大量分析观察,认为杂种 F_1可以是超早亲、同早亲,可以是中间型,也可以是同晚亲、超晚亲。
Preface On the genetic law of wheat precocity, there are many differences in the research of previous studies. There are generally three kinds of opinions: ① that precociousness is dominant, F_1 is the same as early parents or ultra-early parents; ② that premature is not Completely dominant, F_1 showed intermediate between the parents; ③ that premature is recessive, F_1 showed the same late-late or late late pro. In China, in 1958, Nanjing University Department of Biology, Department of Genetics, 1972, 1973, Department of Agronomy, Anhui Agricultural University and other units to do a lot of analysis and observation, that hybrid F_1 can be ultra-early pro, with the early parents, can be intermediate, Is the same pro late, late late pro.
