Embodiment 1

[0025] The present invention uses the Ji 172 line cultivated by the Cotton Research Institute of the Hebei Academy of Agriculture and Forestry Sciences as the experimental material. The main characteristics of this variety belong to the transgenic insect-resistant conventional cotton late spring sowing variety, with a full growth period of 116 days, a plant height of 104.3 cm, and a single fruit branch number of 10.2 1, the node position of the first fruiting branch is 7.3 nodes, 10.9 bolls per plant, the boll weight is 6.0 grams, the clothing percentage is 40.8%, the average length of the upper half is 28.0 mm, the specific breaking strength is 29.1 cN / Tex, and the micronaire value is 4.6 .

[0026] 12 The C heavy ion beam is provided by the HI-13 tandem accelerator of the China Institute of Atomic Energy, and the cotton seeds are irradiated.

[0027] Radiation materials were planted at the Xiaoanshe Experimental Station of the Cotton Research Institute of the Academy of Agr...

Abstract

The invention discloses a method for obtaining cotton mutants by using heavy ion beam mutagenesis. The method comprises the steps of utilizing heavy ion beams to carry out mutagenesis, covering cottonseeds subjected to mutagenesis with films, and then sowing the seeds; transplanting mutagenized plants when two leaves and one sprout of each mutagenized plant grow out; carrying out flower sealing and selfing treatment on all plants of M1 generation; harvesting selfing bolls of single plants after the plants are mature; adopting plant lines for sowing; carrying out analysis and investigation onthe characteristics of plants of M2 generation in a growth period; screening out mutants different in phenotypic variation; harvesting the plants one by one, and continuing planting according to the plant lines until the mutants with stable phenotypic variation are obtained.

Description

technical field [0001] The invention relates to cotton mutants, in particular to a method for obtaining cotton mutants by using heavy ion beam mutagenesis. Background technique [0002] Cotton is one of the important economic crops in my country. It is not only an important raw material for the textile industry, but also a raw material for industries such as national defense and medicine. It occupies an important position in the national economic system. China has been a major cotton producer and consumer in the world for many years, and improving cotton varieties is the most effective and fundamental way to improve the international competitiveness of cotton production. Cotton germplasm resources are the material basis for cultivating new high-yield and high-quality cotton varieties, and play a pivotal role in cotton breeding research. The more excellent cotton germplasm we have, the more extensive the research and utilization, the greater the effect of new variety selecti...
