Description

1. Technical field

[0001] The invention relates to a crop breeding method in the field of agricultural science and technology, which is used for selecting new short-season cotton varieties with early maturation and no premature senescence, green branches and green leaves and white flocs in the hybrid offspring population. 2. Background technology

[0002] The successful breeding of short-season cotton varieties has opened up broad prospects for solving the long-standing contradictions between grain and cotton competition for land and season in my country's cotton regions, and improving the economic and ecological benefits of cotton fields. Low temperature and pest damage, labor saving, investment saving, significant economic benefits, welcomed by cotton farmers.

[0003] The main problem in the short-season cotton breeding process is to coordinate the relationship between prematurity and premature senescence. Precocious maturity is the key to achieving dual cropping of wheat ...
