Abstract

The invention discloses QTL related to buffalo milk production traits and a screening method and application thereof. The screening method of the QTL related to buffalo milk production traits comprises the specific steps of sample collection and genotyping, population genetic analysis, selection signal identification and QTL identification related to buffalo milk production traits. The method specifically comprises: screening out four QTLs (Quantitative Trait Locus) containing the most significant SNP, such as 11_Block2, 12_Block2, 16_Block1 and 19_Block5; applying H1H3, H3H4 or H1H2 in 11-Block2, H2H2 in 12_Block2, H2H2 in 16_Block1, H1H4 in 16_Block1 and H2H4 in 19_Block5 to judge and breed buffalo with excellent milk production traits. Technical support is provided for breeding of buffalo milk with excellent milk production performance, and the method is a new method for auxiliary detection of buffalo milk production traits.

Description

【Technical field】

[0001] The invention relates to the field of biotechnology, in particular to a QTL related to milk production traits of buffaloes, a screening method and application thereof. 【Background technique】

[0002] Buffalo is an important characteristic dairy breed in southern my country. It has excellent milk quality and rich nutrition. It has the reputation of "the king of milk" and is deeply loved by consumers. However, low milk production has become a major scientific issue affecting the development of the buffalo industry. As we all know, the milk production trait is an important economic trait of milk buffalo, which belongs to the quantitative trait and is controlled by the micro-effect polygene. Genetic analysis of buffalo milk production traits will have important scientific significance for improving the yield level of this species.

[0003] With the rapid development of modern biotechnology, great changes have taken place in breeding theory and related ...
