Genomic selection, enabled by whole genome prediction (WGP) methods, is revolutionizing plant breeding. Existing WGP methods have been shown to deliver accurate predictions in the most common settings, such as prediction of across environment performance for traits with additive gene effects. However, prediction of traits with non-additive gene effects and prediction of genotype by environment ...

Multi-environment trials are routinely conducted in plant breeding to select candidates for the next selection cycle. In this study, we compare the prediction accuracy of four developed genomic-enabled prediction models: (1) single-environment, main genotypic effect model (SM); (2) multi-environment, main genotypic effects model (MM); (3) multi-environment, single variance G×E deviation model (...

سندرم آسیت بیماری متابولیکی پرهزینه‌ای است که به دلیل انتخاب شدید برای سرعت رشد وکاهش ضریب تبدیل غذاییدر طیور اتفاق می‌افتد. این سندرم یکی از مهم‌ترین عوامل مرگ‌ومیر در صنعت جوجه گوشتی است و عامل خسارات قابل‌توجه اقتصادی و کاهش آسایش حیوان است. در این تحقیق به ‌منظور یافتن ژن و نواحی ژنومی مؤثر بر سندرم آسیت، مطالعه پویش کل ژنوم (GWAS) با استفاده از یک تراشه SNP 60k ژنوم مرغ در 101پرنده نسل F2 ...

Models for genome-wide prediction and association studies usually target a single phenotypic trait. However, in animal and plant genetics it is common to record information on multiple phenotypes for each individual that will be genotyped. Modeling traits individually disregards the fact that they are most likely associated due to pleiotropy and shared biological basis, thus providing only a pa...

Legumes are extremely valuable because of their high protein content and several other nutritional components. The major challenge lies in maintaining the quantity quality compounds view climate change conditions. global need for plant-based proteins has increased demand seeds with a that includes essential amino acids. Genome-wide association studies (GWAS) have evolved as standard approach ag...

In beef cattle, phenotypic data that are difficult and/or costly to measure, such as feed efficiency, and DNA marker genotypes are usually available on a small number of animals of different breeds or populations. To achieve a maximal accuracy of genomic prediction using the phenotype and genotype data, strategies for forming a training population to predict genomic breeding values (GEBV) of th...

Fillet yield (FY, %) is an economically-important trait in rainbow trout aquaculture that affects production efficiency. Despite that, FY has received little attention in breeding programs because it is difficult to measure on a large number of fish and cannot be directly measured on breeding candidates. The recent development of a high-density SNP array for rainbow trout has provided the neede...

درک کنترل ژنتیکی صفات رشد یکی از مهم‌ترین اهداف اصلاح نژادی در پرورش طیور است. به‌منظور یافتن وراثت پذیری ژنومی صفات رشد، از تراشه تجاری SNP ژنوم مرغ در جمعیت F2 حاصل از تلاقی دوطرفه مرغ بومی آذربایجان و لاین B سویه گوشتی آرین استفاده گردید. وراثت‌پذیری ژنومی با استفاده از روش آماری بهترین پیش بینی نااریب خطی ژنومی (GBLUP) برای صفات یک، سه، پنج، هفت و نه هفتگی وزن بدن و طول شانک برآورد گردید. ب...

Genomic selection is becoming a common practise in dairy cattle, but only few works have studied its introduction in pig selection programs. Results described for this species are highly dependent on the considered traits and the specific population structure. This paper aims to simulate the impact of genomic selection in a pig population with a training cohort of performance-tested and slaught...

Bacterial cold water disease (BCWD) causes significant economic losses in salmonid aquaculture, and traditional family-based breeding programs aimed at improving BCWD resistance have been limited to exploiting only between-family variation. We used genomic selection (GS) models to predict genomic breeding values (GEBVs) for BCWD resistance in 10 families from the first generation of the NCCCWA ...
