From Individual to Stand Performance in Hybrids: Challenging the Optimal Parental Genetic Distance. [PDF]

Evol Appl
ABSTRACT Hybridization, the interbreeding of distinct genotypes, drives evolutionary processes like speciation and adaptation, potentially via phenotypic transgression, where hybrids exhibit novel traits. In crop breeding, research has largely focused on optimizing heterosis to enhance hybrid performance, particularly for traits such as biomass.

Heterosis in plants [PDF]

Current Biology, 2018
Heterosis, also known as 'hybrid vigor', is a well-known phenomenon whereby hybrid offspring resulting from cross pollination exhibit greater vigor than either parent. Here, Hochholdinger and Baldauf provide an overview of this fascinating biological phenomenon and what is known about the underlying genetics and mechanisms.

Dispersed emergence and protracted domestication of polyploid wheat uncovered by mosaic ancestral haploblock inference

Nature Communications, 2022
The contribution of ancient haplotypes to domestication is largely unknown. Here, the authors develop an ancestral genomic haploblock dissection method to generate a mosaic pan-ancestry genomic map and reveal that the domesticated polyploidy wheat ...

Large-scale genomic and transcriptomic profiles of rice hybrids reveal a core mechanism underlying heterosis

Genome Biology, 2022
Background Heterosis is widely used in agriculture. However, its molecular mechanisms are still unclear in plants. Here, we develop, sequence, and record the phenotypes of 418 hybrids from crosses between two testers and 265 rice varieties from a mini ...

Dissection of two QTL clusters underlying yield-related heterosis in the cabbage founder parent 01–20

Horticultural Plant Journal, 2023
Cabbage has significant heterosis and most commercial cultivars are hybrids. To explore genetic basis of cabbage heterosis and promote cabbage heterosis utilization, we constructed two populations by crossing 100 DH lines derived from a cabbage hybrid 01–

Fine Mapping of the Wheat Leaf Rust Resistance Gene LrLC10 (Lr13) and Validation of Its Co-segregation Markers

Frontiers in Plant Science, 2020
Wheat leaf rust, caused by the fungus Puccinia triticina Eriks. (Pt), is a destructive disease found throughout common wheat production areas worldwide.

Transcriptomics reveals a core transcriptional network of K-type cytoplasmic male sterility microspore abortion in wheat (Triticum aestivum L.)

BMC Plant Biology, 2023
Background Cytoplasmic male sterility (CMS) plays a crucial role in hybrid production. K-type CMS, a cytoplasmic male sterile line of wheat with the cytoplasms of Aegilops kotschyi, is widely used due to its excellent characteristics of agronomic ...

Quantitative trait locus analysis of heterosis for plant height and ear height in an elite maize hybrid zhengdan 958 by design III

BMC Genetics, 2017
Background Plant height (PH) and ear height (EH) are two important agronomic traits in maize selection breeding. F1 hybrid exhibit significant heterosis for PH and EH as compared to their parental inbred lines.

HETEROSIS OR NEUTRALITY? [PDF]

Genetics, 1977
ABSTRACT Various statistics have been proposed on an ad hoc basis to test whether alleles at a locus are selectively neutral. By considering population models in which selection operates, this paper shows that the population homozygosity is a powerful test statistic for testing departures from neutrality, in the direction of heterozygote

Assessment of heterosis in two Arabidopsis thaliana common-reference mapping populations. [PDF]

PLoS ONE, 2018
Hybrid vigour, or heterosis, has been of tremendous importance in agriculture for the improvement of both crops and livestock. Notwithstanding large efforts to study the phenomenon of heterosis in the last decades, the identification of common molecular ...
