Linkage Disequilibrium with Linkage Analysis of Multiline Crosses Reveals Different Multiallelic QTL for Hybrid Performance in the Flint and Dent Heterotic Groups of Maize

Héloïse Giraud, Christina Lehermeier, Eva Bauer, Matthieu Falque et autres

Multiparental designs combined with dense genotyping of parents have been proposed as a way to increase the diversity and resolution of quantitative trait loci (QTL) mapping studies, using methods combining linkage disequilibrium information with linkage analysis (LDLA). Two new nested association mapping …

Usefulness of Multiparental Populations of Maize ( Zea mays L.) for Genome-Based Prediction

Christina Lehermeier, Nicole Krämer, Eva Bauer, Cyril Bauland et autres

The efficiency of marker-assisted prediction of phenotypes has been studied intensively for different types of plant breeding populations. However, one remaining question is how to incorporate and counterbalance information from biparental and multiparental populations into model training for genome-wide prediction. To address …

Registration of LONREN-1 and LONREN-2 Germplasm Lines of Upland Cotton Resistant to Reniform Nematode

Alois A. Bell, A. F. Robinson, Jose Quintana, Nilesh D. Dighe et autres

Cotton (Gossypium hirsutum L.) germplasm lines LONREN-1 (Reg. No. GP-977, PI 669509) and LONREN-2 (Reg. No. GP-978, PI 669510) were developed and released by the USDA–ARS, Texas Agricultural Experiment Station and Cotton Incorporated in 2007 to provide breeders with desirable germplasm resistant …

Intraspecific variation of recombination rate in maize

Eva Bauer, Matthieu Falque, Hildrun Walter, Cyril Bauland et autres

BACKGROUND: In sexually reproducing organisms, meiotic crossovers ensure the proper segregation of chromosomes and contribute to genetic diversity by shuffling allelic combinations. Such genetic reassortment is exploited in breeding to combine favorable alleles, and in genetic research to identify genetic factors underlying …

Quantitative Trait Loci for Ruminal Degradability in opaque endosperm2 (o2) Maize

Ntjapa Lebaka, J. G. Coors, R.D. Shaver, Sandy J. Bertics et autres

ABSTRACT Although opaque endosperm2 (o2) gene that alters protein composition of maize (Zea mays L.) endosperm improves dry matter degradability (DMD) in ruminants it is also associated with soft endosperm texture, low yield, and susceptibility to diseases and insects. To circumvent the …

A comparative genomic map for Caulanthus amplexicaulis and related species (Brassicaceae)

A. Millie Burrell, Katherine Taylor, Ryan J. Williams, ROBERT T. CANTRELL et autres

Adaptation to environment is the cornerstone of ecological genetics. The subject of this study is a wild relative of the sequenced and annotated model plant species, Arabidopsis thaliana. Caulanthus amplexicaulis var. barbarae lives on serpentine soils, known for high concentrations of heavy …

Quantitative Trait Loci for Endosperm Modification and Amino Acid Contents in Quality Protein Maize

Andrés Gutiérrez‐Rojas, Javier Betrán, M. Paul Scott, Halima Atta et autres

The deficient protein quality of corn ( Zea mays L.) grain can be improved by replacing normal Opaque2 ( O2 ) alleles with nonfunctional mutant o2 alleles. Unfortunately, o2 alleles are associated with soft endosperm texture, poor yield, and susceptibility to diseases …

Linkage Mapping of Resistance to Reniform Nematode in Cotton following Introgression from Gossypium longicalyx (Hutch. & Lee)

Nilesh D. Dighe, A. F. Robinson, Alois A. Bell, Monica A. Menz et autres

Reniform nematodes (Rotylenchulus reniformis Linford & Oliveira) decrease U.S. production of Upland cotton (Gossypium hirsutum L., 2n = 52, 2[AD]1) by more than US$100 million yr−1 We report here on the mapping of a gene for extreme resistance that was introgressed from …

Phenotypic Characterization of Quality Protein Maize Endosperm Modification and Amino Acid Contents in a Segregating Recombinant Inbred Population

Andrés Gutiérrez‐Rojas, M. Paul Scott, Otto Raúl Leyva–Ovalle, Monica A. Menz et autres

The protein quality of maize (Zea mays L.) can be improved by replacing normal Opaque2 alleles with nonfunctional recessive alleles (o2). Homozygous o2 kernels have increased levels of lysine and tryptophan. Unfortunately, the associated soft texture of the o2 kernels causes poor …
