Cotton fiber quality is defined by several traits, which are affected by genotype×environment interaction (GEI). The objectives of this work were to study GEI of fiber traits, the repeatability and the effect of the size of testing environments in detecting cultivar genetic differences by High Volume Instrument (HVI), and the usefulness of two GEI derived stability indices, σ2i and GGE Instabil...

Stability of breadmaking quality of four Croatian bread winter wheat cultivars was investigated using rheological traits from the farinogram (dough development time, stability, degree of so�ening, water absorption, Hankoczy quality number) and the extensogram (extensibility, maximum resistance, ratio of resistance to extensibility, energy) and the indirect traits (protein content, wet gluten co...

Broiler meat quality is one of the primary factors considered by the poultry industry. This study was conducted to estimate heritability and genetic correlation coefficients for meat quality traits in a single male broiler line. The meat ultimate pH (24 h after slaughter) and lightness presented the highest heritability estimates. Given the estimated genetic correlations, the pH measured at 15 ...

A genome-wide scan for QTL affecting economically important traits in beef production was performed using an F(2) resource family from a Japanese Black x Limousin cross, where 186 F(2) animals were measured for growth, carcass, and meat-quality traits. All family members were genotyped for 313 informative microsatellite markers that spanned 2,382 cM of bovine autosomes. The centromeric region o...

A dramatic increase of growth performance has been achieved through selection for muscle accretion and improvement of nutrition and breeding conditions in meat animals. However, evidence suggests that this may have resulted in altered meat quality. Skeletal muscle is a highly heterogeneous tissue containing myofibres, connective tissue, adipocytes, vascular and neural tissues. Muscle fibres can...

Cereal grains are considered by consumers due to effect on health because of their antioxidant capacity, phenolic content and other phytochemicals. For this purpose, an experiment was conducted to evaluate of morphological and nutritional traits on 10 rice genotypes. Analysis of variance showed a significant different among the genotypes for all traits. Onda, Gharib, Fajr and L2 genotypes had t...

This study was conducted to evaluate the porcine gene GADD45A (growth arrest and DNA-damage-inducible protein 45 alpha) as a positional candidate controlling quantitative trait loci (QTL) for meat quality traits on chromosome 6 (SSC6). Four exons of the porcine GADD45A gene were defined from cDNA and BAC clone sequences. A total of 4 single nucleotide polymorphisms (SNPs) were identified in por...

This study was conducted to determine the combining ability and heritability of rice grain quality traits. Some grain quality traits such as grain length, grain width, milled grain length, milled grain width, length to width ratio, milled rice recovery, head rice recovery, amylose and gel consistency were analyzed using a full diallel mating design in Malaysian rice varieties. This study was co...

The objective of this research was to study the effects of phenological stages on yield and quality traits in 22 populations of tall wheatgrass Agropyron elongatum. A split plot design was conducted using a complete randomized block with two replications in Lorestan (Borujerd), Iran during 2007-2008. The genotypes were cut in five maturity stages as vegetation, stem elongation, heading date, an...
