TL;DR: Wang et al. as mentioned in this paper proposed a whole-genome selection-based method for breeding improved disease resistant fish varieties, thereby overcoming defects in the traditional breeding technology, providing a molecular breeding method for cultivation of improved disease-resistant high-yield fish varieties.
Abstract: The invention aims at providing a whole-genome-selection-based method for breeding improved disease-resistant fish varieties, thereby overcoming defects in the traditional breeding technology, providing a molecular breeding method for cultivation of improved disease-resistant high-yield fish varieties, solving a problem of lack of a whole-genome selection method in the existing fish breeding industry, providing a technical means for improved disease-resistant fish variety breeding of the fish breeding industry, realizing upgrading of the fish breeding technique, and promoting rapid development of the fish breeding industry. The disease-resistant fish offspring obtained by using the method provided by the invention has the enhanced disease-resistant capability. An experiment result demonstrates that the survival rate from infection and breeding survival rate of a disease-resistant fish offspring that is bred based on the whole genome selection method are higher than those of the control group by 20% to 30%. Using the method provided by the invention, the improved disease-resistant fish breed can be bred rapidly and efficiently; and the disease-resistant capability and breeding survival rate of fish can be enhanced. Therefore, the method provided by the invention has the great application value and broad promotion prospects in the fish breeding industry.

TL;DR: In this paper, an identification method of PPARD major gene, establishment of a molecular breeding method and application in the genetic improvement of breeding pigs was discussed. And the authors revealed an identification course of the gene and the cause mutation site and a method for breeding the traits of pig ears, fat deposition, weight of pig head and carcass traits by using the gene marker.
Abstract: The invention relates to an identification method of PPARD major gene, establishment of a molecular breeding method and application in the genetic improvement of breeding pigs In the invention, by adopting the white Duroc * Erhualian Intercross and the Chinese and exotic breeding pigs of distant population, the whole-genome scan and linkage mapping, the IBD fine mapping of the target region based on a high-density SNP mark and the selection effect analysis of the distant population are carried out, and then the major gene, ie, PPARD for deciding the traits of pig ears, fat deposition, weight of pig head and carcass traits, and the mutation site of key cause, ie, G32E are identified The sites are detected by the modern molecular biotechnology; by adopting the gene-assisted selection method, the beneficial gene-typed individuals are selected for the breeding pigs, thereby the breeding improvement efficiency of the traits of pig ears, fat deposition, weight of pig head and carcass traits are remarkably improved The invention further discloses an identification course of the gene and the cause mutation site and a method for breeding the traits of pig ears, fat deposition, weight of pig head and carcass traits by using the gene marker of the invention

TL;DR: In this paper , the collection and conservation of soybean wild relatives and the dissection of their genomic features will accelerate soybean breeding and facilitate sustainable agriculture and food production, which is a major obstacle to soybean improvement.
Abstract: Abstract Genetic diversity is a cornerstone of crop improvement, However, cultivated soybean ( Glycine max ) has undergone several genetic bottlenecks, including domestication in China, the introduction of landraces to other areas of the world and, latterly, selective breeding, leading to low genetic diversity the poses a major obstacle to soybean improvement. By contrast, there remains a relatively high level of genetic diversity in soybean’s wild relatives, especially the perennial soybeans ( Glycine subgenus Glycine ), which could serve as potential gene pools for improving soybean cultivars. Wild soybeans are phylogenetically diversified and adapted to various habitats, harboring resistance to various biotic and abiotic stresses. Advances in genome and transcriptome sequencing enable alleles associated with desirable traits that were lost during domestication of soybean to be discovered in wild soybean. The collection and conservation of soybean wild relatives and the dissection of their genomic features will accelerate soybean breeding and facilitate sustainable agriculture and food production.

TL;DR: In this article, an insertion/deletion (InDel) molecular marker AAD closely-linked to the tomato anthocyanin absent character and application thereof was proposed, which can replace a traditional method of selecting a green plant to ensure that a breeding material of tomato contains an AA mutation site.
Abstract: The invention relates to the field of molecular breeding, and in particular to an insertion/deletion (InDel) molecular marker AAD closely-linked to the tomato anthocyanin absent character and application thereof. The physical position of the InDel molecular marker closely-linked to the tomato anthocyanin absent character is No. 45339693 base to No. 45343097 base on chromosome 2 of tomato. The invention can replace a traditional method of selecting a green plant to ensure that a breeding material of tomato contains an anthocyanin absence (AA) mutation site. An AA site hybrid plant in the breeding material with normal phenotype is assist-selected by mean of the molecular marker, the breeding period can be shortened, and the breeding efficiency can be improved.
