ABSTRACT.
The present study reports preliminary estimates of heritabilities of meat quality traits and genetic correlation among them and with carcass quality based on data on 424 lambs of the Texel Central Progeny Testing in Uruguay. Moderate heritabilities were estimated for color parameters, Warner-Braztler shear force (WBSF), intramuscular fat content (IMF) and fatty acid profile (percentage of saturates, monounsaturated and polyunsaturated fatty acids). Genetic correlations between fat thickness by ultrasound and GR were positive and moderate between them and with IMF. In contrast, rib eye area, which is an indicator of carcass muscling, was negatively correlated with IMF. This meat quality trait is relevant given its association with eating quality traits and nutritional value of lamb meat. The correlation between IMF with WBSF was -0.29 indicating that leaner lamb meat will tend to be less tender. On the other hand, genetic correlations of IMF with fatty acids percentages suggest that lower contents of IMF will have higher proportions of "healthier" fatty acid. Genetic improvement for higher meat yield is possible given the genetic variability estimated, but these preliminary associations suggest the need to take into account simultaneously meat quality traits to avoid any unfavorable effects, due to correlated responses. |

Abstract: Self-incompatibility (SI) is a genetic mechanism preventing self-pollination in ?40% of plant species. Two multiallelic loci, called S and Z, control the gametophytic SI system of the grass family (Poaceae), which contains all major forage grasses. Loci independent
from S and Z have been reported to disrupt SI and lead to self-compatibility (SC). A locus causing SC in perennial ryegrass (Lolium perenne L.) was previously mapped on linkage group (LG) 5 in an F2 population segregating for SC. Using a subset of the same population (n = 68), we first performed low-resolution quantitative trait locus (QTL) mapping to exclude the presence of additional, previously undetected contributors to SC. The previously reported QTL on LG 5 explained 38.4% of the phenotypic variation, and no significant contribution from other genomic regions was found. This was verified by the presence of significantly distorted markers in the region overlapping with the QTL. Second, we fine mapped the QTL to 0.26 centimorgan (cM) using additional 2,056 plants and 23 novel sequence-based markers. Using Italian ryegrass (Lolium multiflorum Lam.) genome assembly as a reference, the markers flanking SC were estimated to span a ?3 Mb region encoding for 57 predicted genes. Among these, seven genes were proposed as relevant candidate genes based on their annotation and function described in previous studies. Our study is a step forward to identify SC genes in forage grasses and provides diagnostic markers for marker-assisted introgression of SC into elite germplasm.
