TLDR
In this paper, a total of 227 QTL were mapped on 18 chromosomes, which formed 35 QTL clusters with consistently positive correlations between yield and its related traits, correlation variations were clearly shown within the QTL cluster.Citations

Wheat glutamine synthetase TaGSr-4B is a candidate gene for a QTL of thousand grain weight on chromosome 4B
TL;DR: In this article , a Glutamine Synthetase TaGSr-4B was selected as a candidate gene for a QTL of thousand grain weight on 4B, and the gene marker is ready for wheat breeding.

TL;DR: In this article , the International Wheat Genome Sequencing Consortium (IWGSC) RefSeq v2.0 physical map of all markers was used to map QTLs associated with leaf spot (Ls), leaf rust (Lr), stripe rust (Yr), and common bunt (Cbt) resistance in two recombinant inbred lines (RIL) populations.

Recovery of inter-block information when block sizes are unequal
H. D. Patterson,Robin Thompson +1 more
TL;DR: In this article, a modified maximum likelihood procedure is proposed for estimating intra-block and inter-block weights in the analysis of incomplete block designs with block sizes not necessarily equal, and the method consists of maximizing the likelihood, not of all the data, but of selected error contrasts.

A NAC Gene Regulating Senescence Improves Grain Protein, Zinc, and Iron Content in Wheat
TL;DR: The positional cloning of Gpc-B1, a wheat quantitative trait locus associated with increased grain protein, zinc, and iron content, is reported here, and reduction in RNA levels of the multiple NAM homologs by RNA interference delayed senescence by more than 3 weeks and reduced wheat grain protein and zinc content.

Map Manager QTX, cross-platform software for genetic mapping.
TL;DR: Map Manager QTX is an enhanced version of Map Manager QT, rewritten with the aid of cross-platform libraries (XVT, Boulder Software Foundry, Inc.), which allow it to be compiled for multiple computer platforms.

The wheat VRN2 gene is a flowering repressor down-regulated by vernalization.
Liuling Yan,Artem Loukoianov,Ann E. Blechl,G. Tranquilli,Wusirika Ramakrishna,Phillip SanMiguel,Jeffrey L. Bennetzen,Viviana Echenique,Jorge Dubcovsky +8 more
TL;DR: Cutting the RNA level of VRN2 by RNA interference accelerated the flowering time of transgenic winter-wheat plants by more than a month and resulted in spring lines, which do not require vernalization to flower.
