Journal ArticleDOI
Identification of Quantitative Trait Loci for Sucrose Content in Soybean Seed
Ailan Zeng,Pengyin Chen,Ainong Shi,Dechun Wang,Bo Zhang,Moldir Orazaly,Liliana Florez-Palacios,Kristofor R. Brye,Qijian Song,Perry B. Cregan +9 more
TL;DR: Three novel QTLs for seed sucrose were mapped to chromosomes 5, 9, and 16, accounting for 46, 10 and 8%, respectively, of the phenotypic variation for sucrose content.
Journal ArticleDOI
Population Structure and Genetic Diversity of the Trinitario Cacao (Theobroma cacao L.) from Trinidad and Tobago
Elizabeth S. Johnson,Elizabeth S. Johnson,Frances L. Bekele,Steven J. Brown,Qijian Song,Qijian Song,Dapeng Zhang,Lyndel W. Meinhardt,Raymond J. Schnell +8 more
TL;DR: A strong genetic basis is provided for the industry distinction of Trinitario and Ecuadorian cacaos and for the curatorship and maintenance of industry fl avor classes while breeding for disease resistance in cacao.
Journal ArticleDOI
QTL analysis of symbiotic nitrogen fixation in a black bean population.
Journal ArticleDOI
Fine Mapping and Characterization of Candidate Genes that Control Resistance to Cercospora sojina K. Hara in Two Soybean Germplasm Accessions.
Anh-Tung Pham,Donna K. Harris,James W. Buck,Aaron Hoskins,Jonathan Serrano,Hussein Abdel-Haleem,Perry B. Cregan,Qijian Song,H. Roger Boerma,Zenglu Li +9 more
TL;DR: Based on phenotype, genotype and haplotype analysis results, these two soybean accessions might carry different resistance alleles of the same gene or two different gene(s) that are controlled by a novel gene on chromosome 13 that is different from Rcs3.
Journal ArticleDOI
Genome-wide association mapping of resistance to Phytophthora sojae in a soybean [Glycine max (L.) Merr.] germplasm panel from maturity groups IV and V.
TL;DR: The identified molecular markers and genomic regions that are associated with the disease resistance in this gene pool will greatly assist the U.S. Southern soybean breeders in developing elite varieties with broad genetic background and P. sojae resistance.
