Abstract

Several previous studies have indicated the presence of gene or gene families involved in fleece traits in different species. The aim of this study was to confirm the location of a QTL on chromosome (CHI) 1 and the location of a new QTL on CHI5 using new microsatellites and enlarged families in Angora goats. The population analyzed had a total of 418 kids from 10 Angora bucks. The number of half-sib offspring per buck ranged between 26 to 73 kids. Eight phenotypic fleece traits were recorded. An interval analysis was performed under a half-sib model using the QTL Express program. Our results confirm a QTL for CVAFD on CHI1 in Angora goats and we found a new QTL for KEMP on CHI5. Nevertheless, new families, increased number of kid in extant families and a fine mapping on the candidate regions should be the next steps to carry out.
