试验经过和方法1974年正式开展研究,当时供试材料为10个2-2-3不育株系及其衍生系,按株系点播,抽穗后套袋逐株检查育性及对可育株进行结实率调查,并于1974年冬利用温室材料进行雄蕊发育过程的镜检观察,到1977年对2-2-3育性遗传行为取得了大量比较完整的数据。经过6个世代遗传鉴定,1977年秋确认为它是一个“无花粉型”受显性单基因控制的核不育小麦,并命名为晋型核不育遗传类型。1978—1981年利用这个核不育材料为不去雄母本,与
After the test and method of formally launched in 1974, when the test materials for the 10-2-3-3 sterile lines and their derived strains, on-demand by plant, bagging after heading to check fertility and fertile plants The investigation of the seed setting rate and the microscopic observation of stamen development using greenhouse material in the winter of 1974 showed that a large amount of comparative data were obtained on the genetic behavior of 2-2-3 fertility in 1977. After six generations of genetic identification, the autumn of 1977 was identified as a “non-pollen-type” nuclear-sterile wheat under the control of a dominant single gene and was named the genotype of Jin-type nuclear infertility. 1978-1981 The use of this material to prevent male and female infertility, and
