OsLG3 contributing to rice grain length and yield was mined by Ho-LAMap

BMC Biology, 2017
Background Most agronomic traits in rice are complex and polygenic. The identification of quantitative trait loci (QTL) for grain length is an important objective of rice genetic research and breeding programs.

Breeding for multi‐stress resilience in crops: Myth or possibility?

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change threatens millions of farmers worldwide by exposing crops to multiple concurrent or sequential environmental stresses such as drought, heat, waterlogging, and diseases. Although crops have long been selected under naturally occurring multi‐stress conditions, breeding pipelines largely focus on optimal or single‐stress environments ...

The role of epistasis in the manifestation of heterosis: a systems-oriented approach

, 2007
Heterosis is widely used in breeding, but the genetic basis of this biological phenomenon has not been elucidated. We postulate that additive and dominance genetic effects as well as two-locus interactions estimated in classical QTL analyses are not ...

Estimation and Testing of Gene Expression Heterosis [PDF]

, 2014
Heterosis, also known as the hybrid vigor, occurs when the mean phenotype of hybrid offspring is superior to that of its two inbred parents. The heterosis phenomenon is extensively utilized in agriculture though the molecular basis is still unknown.

Natural variation of STKc_GSK3 kinase TaSG-D1 contributes to heat stress tolerance in Indian dwarf wheat

Nature Communications
Heat stress threatens global wheat (Triticum aestivum) production, causing dramatic yield losses worldwide. Identifying heat tolerance genes and comprehending molecular mechanisms are essential. Here, we identify a heat tolerance gene, TaSG-D1 E286K , in

Genetic Evaluation of Pure Line Laying Hens Based on Crossover Testing Data From Simulated Populations

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Commercial laying hen breeding programs aim to maximize the performance of crossbred animals. However, selection is usually based on data from pure lines raised in controlled nucleus environments, which may not fully predict the yields under commercial conditions.

Heterosis in chickpea [PDF]

, 1976
CHICKPEA (Cicer arietinum L.) is a highly self-pollinated crop and the scope for exploitation of hybrid vigour will depend on the direction and magnitude of heterosis, biological feasibility and the type of gene action involved.

Heterosis for characters governed by two genes [PDF]

, 1977
An expression for heterosis over midparent is derived for characters governed by one gene when hybrids are made using arbitrarily inbred parents. It is shown that, so long as inbreeding does not depress the vigour and fitness of parents, heterosis in ...

Genetic and Phenotypic Correlations Among Growth, Disease Occurrence, and Reproductive Performance From Calf to Heifer in Girolando Dairy Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The Girolando breed, a cross between Holstein (Bos taurus) and Gir (Bos indicus), is the primary choice for dairy production in Brazilian tropical regions, as it combines high productive potential with adaptation to the tropical environment.

TaTCP6 is required for efficient and balanced utilization of nitrate and phosphorus in wheat

Nature Communications
High crop yields require adequate nutrients, particularly nitrate (N) and phosphorus (P). Identifying regulators for efficient N-P utilization is critical in wheat.
