Structural Variations Contribute to Subspeciation and Yield Heterosis in Rice
Plant Biotechnology Journal, EarlyView.ABSTRACT Yield heterosis has been extensively exploited in hybrid breeding, with intersubspecific hybrids often exhibiting the most pronounced effects. However, developing elite hybrids remains a laborious and time‐consuming process. The genetic basis of heterosis has been debated for over a century, hindered largely by the lack of high‐quality genomes.

Resolving discrepancies between chimeric and multiplicative measures of higher-order epistasis
Nature CommunicationsEpistasis - the interaction between alleles at different genetic loci - plays a fundamental role in biology. However, several recent approaches quantify epistasis using a chimeric formula that measures deviations from a multiplicative fitness model on an

Plant Biotechnology Journal, EarlyView.ABSTRACT Sucrose transport and starch accumulation are crucial carbohydrate metabolic processes in rice, playing essential roles during late pollen development to ensure pollen maturation, fertility and high grain production. However, the molecular mechanisms regulating sucrose transport and starch accumulation during rice pollen development remain ...

Detection of epistasis in chickpea
, 2021 Triple test cross-analysis was used to detect epistasis in chickpea. None of the characters investigated exhibited epistasis. In the absence of epistasis, additive and dominance effects were estimated.

A Century of Understanding and Harnessing Heterosis
Plant Breeding, EarlyView.ABSTRACT Heterosis has shaped modern plant breeding since Darwin's 19th century observations that outcrossing restores vigour lost through selfing. While 100 years old, its mechanistic basis and deployability remain actively debated. Classical models of dominance, overdominance and epistasis provided the foundation for hybrid breeding and converted ...

Detection of epitasis, additive and dominance variation in rice (Oryza sativa L.) using triple test cross analysis [PDF]
Electronic Journal of Plant Breeding, 2014 An investigation was carried out to detect the epistasis, additive and dominance components of genetic variance for yield and yield attributing traits through triple test cross analysis, involving three testers (P1, P2 and their F1) and ten lines of rice.

Plant Breeding, EarlyView.ABSTRACT Sorghum [Sorghum bicolor (L.) Moench] is a vital cereal crop in dry regions worldwide. However, in sub‐Saharan Africa (SSA), grain yields from currently grown varieties remain low (< 1 ton/ha) and exhibit variable nutrient composition. Therefore, the objective of this study was to undertake a genetic analysis of selected East African‐adapted ...

Considerations in the search for epistasis
Genome BiologyAbstract Epistasis refers to changes in the effect on phenotype of a unit of genetic information, such as a single nucleotide polymorphism or a gene, dependent on the context of other genetic units. Such interactions are both biologically plausible and good candidates to explain observations which are not fully explained by an additive ...
