LOW TEMPERATURE RESISTANCE-RELATED SNP MOLECULAR MARKER OF LITOPENAEUS VANNAMEI, AND DETECTION PRIMER AND USE THEREOF

摘要

A low temperature resistance-related SNP molecular marker of Litopenaeus vannamei, and a detection primer and a use thereof The sequence of the SNP molecular marker is as shown in SEQ ID NO. 1, and the SNP molecular marker of Litopenaeus vannamei is: a G/C genotype or a G/G genotype at nucleobase position 1,925 of the sequence shown in SEQ ID NO.1; or an A/A genotype or an A/C genotype having nucleobases 3,414, 3,475, and 3,537 completely linked; or a T/T genotype or a T/G genotype at nucleobase position 3,776; or an A/C genotype or an A/A genotype at nucleobase positions 6,679. The molecular marker and the detection primer and the use thereof help to rapidly improve the low temperature resistance of Litopenaeus vannamei offspring, shortening the breeding cycle of the low-temperature resistant prawn lineages, and thus having great potential value in application.
