Abstract

Anthranilate synthase allele fragments for increasing rice yields and uses thereof. A method of differentiating rice materials with a superior allele associated with high yield includes: (1) detecting a genotype of rice to be detected based on a specific gene fragment; where the specific gene fragmentOsASA1 is located in rice genome, and there are typically two allelic forms of OsASA1, OsASA1_a shown as SEQ ID NO. 1 and OsASA1_b shown as SEQ ID NO. 2; and (2) determining and comparing the average yield of a rice population with a genotype of homozygous OsASA1_b and that of a rice population with a genotype of homozygous OsASA1_a under the same growth conditions in different geographical regions. The rice population with the genotype of homozygous OsASA1_b shows a higher average yield than the rice population with the genotype of homozygous OsASA1_a.
