ABSTRACT.
A first integrated linkage map of Acca sellowiana (Berg.) Burret (2. n= 2. x= 22), commonly known as 'pineapple guava' was constructed using a 160 (TCO. ×. BR) full-sib F1 progeny based on intersimple sequence repeat (ISSR), amplified fragment length polymorphism (AFLP) and simple sequence repeat (SSR) markers. To develop an integrated map, we used a novel statistical approach that provided a simultaneous estimation of linkage and linkage phases based on maximum-likelihood analysis. The integrated map comprised 219 (27 ISSRs and 192 AFLPs) linked markers that were assigned to 10 major linkage groups (LG) representing a total map length of 2875. cM and average distance between markers of 13.8. cM. TCO (14 LG, 83 markers, 1264.6. cM) and BR (18 LG, 94 markers, 1295.1. cM) parent maps were also constructed through the same statistical approach but using only appropriate pseudo-testcross configuration markers. All the LG of the integrated map shared markers with either TCO or, BR or both parental maps. The integrated map provides a framework for further genetic and genomic analyses in A. sellowiana.

ABSTRACT.
Background: As more and more genotypes become available, accuracy of genomic evaluations can potentially increase. However, the impact of genotype data on accuracy depends on the structure of the genotyped cohort. For populations such as dairy cattle, the greatest benefit has come from genotyping sires with high accuracy,
whereas the benefit due to adding genotypes from cows was smaller. In broiler chicken breeding programs, males have less progeny than dairy bulls, females have more progeny than dairy cows, and most production traits are recorded for both sexes. Consequently, genotyping both sexes in broiler chickens may be more advantageous than
in dairy cattle.
Methods: We studied the contribution of genotypes from males and females using a real dataset with genotypes on 15 723 broiler chickens. Genomic evaluations used three training sets that included only males (4648), only females (8100), and both sexes (12 748). Realized accuracies of genomic estimated breeding values (GEBV) were
used to evaluate the benefit of including genotypes for different training populations on genomic predictions of young genotyped chickens.
Results: Using genotypes on males, the average increase in accuracy of GEBV over pedigree-based EBV for males and females was 12 and 1 percentage points, respectively. Using female genotypes, this increase was 1 and 18 percentage points, respectively. Using genotypes of both sexes increased accuracies by 19 points for males and 20
points for females. For two traits with similar heritabilities and amounts of information, realized accuracies from cross-validation were lower for the trait that was under strong selection.
Conclusions: Overall, genotyping males and females improves predictions of all young genotyped chickens, regardless of sex. Therefore, when males and females both contribute to genetic progress of the population, genotyping both sexes may be the best option.
