Meeting Abstract: P18. Shell thickness at age 53 weeks (ST53) and egg albumin weight at 33 weeks (AW33) differ by 7.5% and 3.3%, respectively, in Rhode Island Red and Polish Green-legged Partrigenous layers. Analysis of cosegregation in hybrids revealed linkage between ST53 and microsatellite MCW0114 (full linkage) and between AW33 and MCW0170 (1 cM). Chicken genetic map comparisons showed that ADL0241 and LEI0081 were the closest microsatellites to ST53 and AW33 QTLs, respectively. Chicken BAC-libraries 032- JF256-BI and 032-JF256-RI were screened with MCW0114, MCW0170, ADL0241 and LEI0081 and fifteen clones were identified and PCR-controlled. Biotin-labeled BACs were FISH-mapped to chicken mitotic chromosomes. Hybridization signals were detected within two regions: GGA4q11- 12 (BACs containing MCW0114 and ADL0241) and GGA4q21-22 (BACs containing MCW0170). This data will help positional cloning of AW33 and ST53 QTLs.
