Abstract
Description
technical field
[0001] The invention relates to the field of popularization and application of hybrid insect-resistant cotton F1, in particular to a technical method for asexual rapid propagation and resistance enhancement of hybrid insect-resistant cotton F1. Background technique
[0002] At present, the main types of cotton cultivated are conventional cotton and hybrid cotton. 70% of the cotton area in the Yangtze River Basin is planted with F1, an insect-resistant hybrid cotton that is crossed between varieties. The production of hybrid cotton seeds among existing varieties all adopts artificial detasseling, artificial pollination and hybridization to obtain hybrid F1 seeds. Its main disadvantages are:
[0003] (1) For the production of hybrid cotton seeds, parental breeding and hybrid seed production must be carried out separately, and impurities and impurities must be removed every year.
[0004] (2) Disorderly competition in seed production bases makes it difficult...
