Heterosis studies for quantitative traits in sesame (Sesamum indicum L.)

Electronic Journal of Plant Breeding, 2013
A study was conducted in sesame (Sesamum indicum L.) at Department of Botany, Pratishthan Mahavidyalaya, Paithan,Aurangabad (M.S.) to assess the extent of the heterosis for sixteen quantitative traits including seed yield per plant.

Heterosis Is Prevalent for Multiple Traits in Diverse Maize Germplasm

PLoS ONE, 2009
BackgroundHeterosis describes the superior phenotypes observed in hybrids relative to their inbred parents. Maize is a model system for studying heterosis due to the high levels of yield heterosis and commercial use of hybrids.MethodsThe inbred lines ...

Additive and Partially Dominant Effects from Genomic Variation Contribute to Rice Heterosis [PDF]

Advanced Science
Heterosis, or hybrid vigor, describes the superior performance of F1 hybrids relative to their parents. Despite its significant importance in crop breeding, the molecular mechanisms underlying heterosis remain debated, mainly attributable to ...

Genetic Dissection of Wheat Heterosis Identifies Candidate Genes in Biparental and Diverse Hybrid Populations. [PDF]

Plant Biotechnol J
ABSTRACT Understanding how numerous heterotic quantitative trait loci (hQTL) shape heterosis and shifting from hQTL to candidate genes are central challenges. To address these challenges, we performed a systematic, genome‐wide mapping in a biparental population and a population of diverse hybrids.

Genome-wide association and genomic prediction for resistance to southern corn rust in DH and testcross populations

Frontiers in Plant Science, 2023
Southern corn rust (SCR), caused by Puccinia polysora Underw, is a destructive disease that can severely reduce grain yield in maize (Zea mays L.). Owing to P. polysora being multi-racial, it is very important to explore more resistance genes and develop

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 ...

Brassica napus Transcription Factor Bna.A07.WRKY70 Negatively Regulates Leaf Senescence in Arabidopsis thaliana

Plants, 2023
Leaf senescence is the final stage of leaf development and is essential for storage properties and crop productivity. WRKY transcription factors have been revealed to play crucial roles in several biological processes during plant growth and development,
