The invention discloses mutant gene Oslrt1 for controlling rice non-lateral-root trait, detection and application thereof, and the genomic full length of the gene is 2672 bp, contains 5 exons, and hasa G-A base mutation at the 15th position of a second exon. The nucleotide sequence is as shown in SEQ ID NO.1, the mutant gene hinders the development of lateral roots of rice, and a mutant has almost no lateral root growth. The mutant gene Oslrt1 can be used to regulate the expression of a protein for encoding the rice non-lateral-root trait in rice breeding, and rice with excellent roots can bebred. 种控制水稻无侧根性状的突变基因Oslrt1、其检测及应用，其基因组全长2672bp，含有5个外显子，在第2外显子的第15位处有G-A的碱基突变，其核苷酸序列如SEQ ID NO.1所示，该突变基因使水稻侧根发育受阻，表现为突变体基本没有侧根生长，利用突变基因Oslrt1，可在水稻育种中用于调控编码水稻无侧根性状蛋白质的表达，选育出根系优良的水稻。
