SNP molecular markers for identifying specific strength and micronaire value of cotton fiber and applications thereof

The invention discloses SNP molecular markers for identifying the specific strength and micronaire value of cotton fiber and applications thereof. The two SNP molecular markers respectively are chr23_16630630 and chr23_16596338; the chr23_16630630 is located at the position 201 of the nucleotide sequence shown as SEQ ID No. 1, and the base at the position is T or C; and the chr23_16596338 is located at the position 201 of the nucleotide sequence shown as SEQ ID No. 2, and the base at the position is A or G. The two SNP markers are discovered on the basis of QTL positioning, have significant effects on identifying the specific strength and micronaire value of fiber, and can be used for the molecular mark assisted breeding of the specific strength and micronaire value of cotton fiber. 本发明公开了鉴定棉花纤维比强度和马克隆值的SNP分子标记及应用，所述SNP分子标记有两个，分别为chr23_16630630和chr23_16596338；chr23_16630630位于SEQ ID No.1所示的核苷酸序列的第201位，且该处碱基为T或C；chr23_16596338位于SEQ ID No.2所示的核苷酸序列的第201位，且该处碱基为A或G。本发明在QTL定位基础上发现两个SNP标记，这两个标记在鉴定纤维比强度和马克隆值方面效果显著，可
