High mutation rate in prolactin intron 2 regulates egg-laying performance in Wanjiang white goose

摘要

As the progeny of the two-line hybridisation of the Wanxi Goose and Sichuan Goose, Wanjiang white goose's fertility is unstable. To improve reproduction and select molecular marker associated with egg performance of Wanjiang white goose, PCR-SSCP was applied to detect SNPs in PRL intron 2. Five genotypes were found: AA, AB, BC, CC and DD genotypes. More than 30 SNPs were found in the PCR products Statistical results show that the polymorphism of the five genotypes is significantly related to the egg productivity. The differences of egg-laying level between BC and AA, AB, CC, DD genotypes are extremely significant (p0.01). AA and AB genotypic geese yield more eggs than BC and DD genotypes. It could be used as a molecular marker for selecting high-productivity geese.View full textDownload full textKeywordsWanjiang white goose, prolactin (PRL), egg performance, PCR-SSCPRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/09712119.2011.607688
