Research progress of cotton molecular marker-assisted breeding

Abstract: Molecular marker technology is one of the most important auxiliary means of cotton genetic breeding, which has made a significant progress in cotton molecular marker breeding research. This article gave an overview of the research progress in analysis of genetic diversity, prediction of heterosis, identification of germplasm, genes mapped and marker-assisted selection breeding. In addition, problems appearing in the application process of cottom molecular marker technology would be discussed in order to expect it to be better used in genetic breeding, which would provide more powerful auxiliary means for selecting and cultivating new cotton cultivars that possessed superior multiple traits.

Advances in genetic and statistical models to predict breeding values.

Abstract: INTRODUCTION Even with the tremendous advances that have been made in molecular genetics, it is still not possible to directly observe breeding values. Thus, observable information must be used to statistically predict breeding values. One of the components of this prediction problem is the use of genetic and statistical models to relate observable information to unobservable breeding values. An important aspect of this component is the development of models that are realistic and yet lend themselves to statistical methods of prediction that are computationally feasible.

Forthcoming Perspectives in MAS

Abstract: MAS can be simply defined as selection for a trait based on the genotype of an associated marker rather than the trait itself. In essence, the associated marker is used as an indirect selection criterion. The potential of MAS as a tool for crop improvement has been extensively explored in different plant species. This chapter elaborates what would be the future of molecular breeding strategies in several crops.

SNP molecular markers related to chicken-fertilization duration time characters and application thereof

Abstract: The invention provides SNP molecular markers related to chicken-fertilization duration time characters and an application thereof. TGFB3 genes are subjected to polymorphic researching and association analysis with the association analysis method, and the SNP molecular markers related to the chicken-fertilization duration time characters are found from first introns of the chicken TGFB3 genes for the first time; the SNP molecular markers particularly relate to four SNP molecular markers related to hen-fertilization duration time characters and the positioning and the application of a haplotype formed by the four SNP molecular markers. The SNP molecular markers are obtained through association analysis, and the nucleotide sequences of the SNP molecular markers are shown as SEQ ID NO:1-4. The molecular markers and the haplotype can be used for molecular breeding of chicken-fertilization duration time.
