本发明公开一种与棉花纤维产量相关的NAC蛋白编码基因GhIFY分子标记及其应用，属于生物技术应用领域。棉花NAC蛋白编码基因GhIFY的启动子序列存在两种单倍型，单倍型1的启动子序列如SEQ ID NO.1所示，单倍型2的启动子序列如SEQ ID NO.2所示，单倍型1较单倍型2在启动子序列的第-1634bp处存在一个5103bp的逆转座子的插入；单倍型1的纤维产量衣分性状优于单倍型2。选择携带逆转座子序列如SEQ ID NO.1所示NAC蛋白编码基因GhIFY的待测棉花种质材料作为高产量性状的棉花种质，用于棉花育种。该分子标记在改良棉花纤维产量性状，以及培育高产棉花新品种中具有重要作用和应用前景。
