Combining ability from complete diallel design of Camellia oleifera: Implications for the utility of GCA and SCA in oil-related traits breeding
油茶 油脂性状 遗传差异
2024/5/10
Crossbreeding of the elite clones is an important strategy to breed the new germplasms of Camellia oleifera capable of higher oil yield and quality. While the genetic control model and heterosis of oi...
Enabling Breeding Selection for Biomass in Slash Pine Using UAV-Based Imaging
Slash Pine Breeding Selection Biomass
2023/6/2
Background: Traditional methods used to monitor the aboveground biomass (AGB) and belowground biomass (BGB) of slash pine (Pinus elliottii) rely on on-ground measurements, which are time- and cost-con...
Distribution of bacterial blight resistance genes in the main cultivars and application of Xa23 in rice breeding
rice bacterial blight distribution Xa23 marker-assisted selection
2023/4/21
Bacterial blight (BB) is an important constraint on achieving a high and stable rice grain yield. An increasing number of BB resistance (R) genes have been identified and cloned to increase the availa...
Response to selection of a breeding program for Suffolk sheep in the Czech Republic
lamb breeding values growth performance traits performance recording
2018/11/23
Lamb growth performance traits in relation to parental breeding values (BVs) for these traits were evaluated in a purebred Suffolk sheep population in the Czech Republic. The research lasted over 8 ye...
Genome-association analysis of Korean Holstein milk traits using genomic estimated breeding value
Korean Holstein Genome-wide Association Studies (GWAS) Milk Production Milk Fat Milk Protein
2017/3/9
Holsteins are known as the world’s highest-milk producing dairy cattle. The purpose of this study was to identify genetic regions strongly associated with milk traits (milk production, fat, and protei...
Variance components,heritability estimates,and breeding values for performance test traits in Old Kladruber horses
harness horse genetic parameters performance test genetic resource
2016/9/1
The Old Kladruber horse is an important Czech genetic resource. In the current study, two categories of traits were evaluated – the first, a numerical score for Type and Gender Expression and the seco...
Relationships between Single Nucleotide Polymorphism Markers and Meat Quality Traits of Duroc Breeding Stocks in Korea
uroc Single Nucleotide Polymorphism Markers Carcass Trait Meat Quality Fatty Acid Composition
2016/11/10
This study was conducted to determine the relationships of five intragenic single nucleotide polymorphism (SNP) markers (protein kinase adenosine monophosphate-activated γ3 subunit [PRKAG3], fatty aci...
Triploid plants have larger organs, greater biomass, and strong stress resistance by preserving relatively larger amounts of photosynthetic energy. The undesirable spread of non-native invasive crop a...
Optimization of Swine Breeding Programs Using Genomic Selection with ZPLAN+
Breeding Program Genomic Selection Swine ZPLAN+
2016/5/20
The objective of this study was to evaluate the present conventional selection program of a swine nucleus farm and compare it with a new selection strategy employing genomic enhanced breeding value (G...
Number of Calves Produced at Specified Age as a Measure of Reproductive Performance in Beef Cattle under Artificially-Inseminated Breeding Scheme
Beef Cattle Genetic Parameter Number of Calves Produced Reproductive Performance
2016/4/29
Reproductive abilities in beef cattle herds are receiving increased attention due to recent rises in production costs. To achieve more efficient management, a measure of fertility, namely the number o...
