Beschreibung
Zusammenfassung:	The invention discloses a method for identification or assisted identification of early-maturing traits in upland cotton. The method for identification or assisted identification of early-maturing traits in upland cotton comprises the following steps: detecting a genotype in a genome DNA of to-be-detected upland cotton on the basis of a G1001ASNP site, and determining the to-be-detected upland cotton as candidate upland cotton having early-maturing traits when the genotype is AA homozygotic type or AG heterozygous type and determining the to-be-detected upland cotton as candidate upland cotton having later-maturing traits when the genotype is GG homozygotic type, wherein the G1001A SNP site is the 1001st nucleotide from 5' terminal of a sequence 1 in a sequence list, on 13562854th site of upland cotton Dt3 chromosome. Experiments prove that the early-maturing traits in upland cotton can be screened by detecting the genotype of the to-be-detected upland cotton based on the G1001A SNP; and the application plays an important role in molecular breeding of normal upland cotton.
