The role of domestication and maternal effects on seed traits of crop–wild sunflower hybrids (Helianthus annuus)
(Wiley, 2017-08-18)
Hybridization between crops and their wild relatives may promote the evolution of weeds. Seed germination and dormancy are the earliest life-history traits and are highly influenced by the maternal parent. However, the ...
Phenotypic selection under two contrasting environments in wild sunflower and its crop‐wild hybrid
(Wiley Blackwell Publishing, Inc, 2019-06-05)
Hybridization is a common phenomenon in plants and can lead to the introgression of alleles from one population into another, generate new hybrid lineages, or cause species extinction. The environmental conditions and the ...
In situ conservation of the wild relative of the common bean (Phaseolus vulgaris var. aborigineus) at the south of its neotropical distribution: environmental characterization of a population in central Argentina
(Springer, 2015-01)
The common bean (Phaseolus vulgaris L.) is a food of worldwide vital importance. Like any crop, the conservation of its wild relatives is essential to maintain the genetic variability needed for plant breeding. In situ ...
An update on genetically modified crops
(Pontificia Universidad Católica de Chile. Facultad de Agronomía e Ingeniería Forestal, 2008)
Heat stress effects on reproductive traits in cultivated and wild sunflower (Helianthus annuus L.): evidence for local adaptation within the wild germplasm
(Springer, 2018-08-01)
Heat stress (HS) is a major threat to current and future crop production. Crop improvement for HS tolerance is a major tool for dealing with HS and crop wild relatives (CWR) offer the greatest variability for such improvement. ...
Intentional and unintentional selection during plant domestication: herbivore damage, plant defensive traits and nutritional quality of fruit and seed crops
(Wiley Blackwell Publishing, Inc, 2021-05)
Greater susceptibility to herbivory can arise as an effect of crop domestication. One proposed explanation is that defenses decreased intentionally or unintentionally during the domestication process, but evidence for this ...
A Case for Crop Wild Relative Preservation and Use in Potato
(Crop Science Society of America, 2013-05)
Crop wild relatives (CWR) offer a critical resource to address food security needs by providing genetic diversity for crop improvement, leading to increased plasticity and productivity of farming systems. However, plant ...
Genetic diversity in Oryza glumaepatula wild rice populations in Costa Rica and possible gene flow from O. sativa
(2016-04-07)
Wild crop relatives are an important source of genetic diversity for crop improvement. Diversity estimates are generally lacking for many wild crop relatives. The objective of the present study was to analyze how genetic ...
