The invention belongs to the technical field of plant genetic engineering, and particularly discloses application of a cotton gene and an SNP marker thereof in regulation and control of interknot length of cotton fruits. The invention provides an application of a cotton gene in regulation and control of interknot length of cotton fruits, and also provides an SNP marker linked with the cotton gene and an application of the SNP marker. The cotton gene in the cotton is subjected to overexpression or gene knockout to change the interknot length of the cotton fruit; meanwhile, the SNP marker provided by the invention is used for molecular marker-assisted selection, so that the purposes of detecting the interknot length of the cotton fruit and breeding are achieved. The method has practical application significance for cultivating cotton varieties suitable for mechanical harvesting and simplified cultivation. 本发明属于植物基因工程技术领域，具体公开了棉花基因及其SNP标记在调控棉花果枝节间长度中的应用。本发明提供棉花基因在调控棉花果枝节间长度中的应用，同时提供与所述棉花基因相连锁的SNP标记及其应用。通过将棉花中所述棉
