A question which often arises in studies on the origin and evolution of cultivated plants is whether a weedy race of a crop plant is ancestral to the crop or whether it is necessary to look further for a wild progenitor. Work on a number of different crop-weed complexes has shown that three types of relationship are possible. The weed may have given rise to the crop, as appears to have happened in rye, oats and hemp (Vavilov, 1926). In other cases, such as radish (Panetsos and Baker, 1967) and… 
Wild-weed-crop complexes of common bean (Phaseolus vulgaris L., Fabaceae) in the Andes of Peru and Colombia, and their implications for conservation and breeding
TLDR
Interbreeding complexes of wild and cultivated common bean were observed in both Peru and Colombia, suggesting that the complexes had undergone a long evolution and could be an effective means to generate genetic variability, introgressing genes from wild populations into cultivated types and complementing modern plant breeding programs.
Chile Peppers (Capsicum spp.)
TLDR
The earliest convincing evidence of domesticated chiles follows a gap of over 1500 years in the archaeological record, and concerns about genetic erosion have prompted studies on the distribution of genetic variation in wild and cultivated populations and led to recommendations for collecting for ex situ conservation.
Biosystematics of crop-weed complexes
TLDR
Phylogenetic relationships and the extent of gene exchange between crop and weed affect the amount of genetic diversity and the likelihood that weed populations will provide a source of useful characters for improvement of the crop, hence are relevant in collection and conservation of crop genetic resources.
AN ELECTROPHORETIC STUDY OF EVOLUTION IN CAPSICUM (SOLANACEAE)
TLDR
The technique of starch gel electrophoresis is used to provide data for a different perspective of evolution in Capsicum, suggesting two lines of evolution which may eventually require some realignment at the generic level.
Multiple lines of evidence for the origin of domesticated chili pepper, Capsicum annuum, in Mexico
TLDR
The results suggest that food crops in Mexico had a multiregional origin with chili pepper originating in central-east Mexico, maize in the Balsas River Basin and common bean in the Lerma–Santiago River Basin, resembling similar finds for the Fertile Crescent and China.
Relationships ofAmaranthus caudatus
TLDR
Three species ofAmaranthus are cultivated for their edible seeds: A. caudatus, the semidomesticate, and A. hybridus, native to Mexico and Guatemala, while the third originated in the Andes.
Genetic resources and breeding of Capsicum spp.
TLDR
Five species of Capsicum have been domesticated in the American tropics, but breeding programs have concentrated on the non-pungent cultivars of C. annuum, supporting theoretical calculations that there will be significant amounts of genetic diversity within as well as between species.
Interspecific Hybridization in Pepper Species

Interspecific hybridization is a common situation in the emergence of new species in natural flora. As a result of crosses frequently seen in species in the genus such as Helianthus, Triticum,
Genetic Variability in Germplasm Accessions of Capsicum annuum L
TLDR
Genetic divergence among 38 accessions collected from diverse locations in India was estimated from the data pooled over 3 consecutive years for 15 morphological, growth and chemotypic characters that included days to first and second flowering, fruit onset and fruit onset.
Morphological and genetic relationships between wild and domesticated forms of peppers (Capsicum frutescens L. and C. chinense Jacquin).
TLDR
A significant correlation was found between morphological and molecular characterization, and the combination of the two analyses was effective in identifying and classifying the wild forms and contributing to evolutionary studies in the genus.

Abstract Study of archaeological material of chili peppers (Capsicum spp.) from the sites of Huaca Prieta and Punta Grande on the coast of Peru has shown that the first species to be cultivated was
Virus-like syndromes of Cucurbita species hybrids
TLDR
The ability of virus-like syndrome plants to produce normal runners spontaneously argues against an infective agent such as a virus being the responsible agent, and suggests that the syndrome is of genetic origin rather than induced by a virus.
Studies on the Origin of Cultivated Plants
TLDR
The great increase in genetical research and the marked desire of many geneticists to link their studies with other aspects of biology is leading to renewed interest in the taxonomic and geographical history of the authors' common cultivated plants.
SYSTEMATICS AND THE ORIGIN OF CULTIVATED PLANTS
TLDR
It is surprising to learn how many of the minor cultivated plants have received virtually no attention from taxonomists, and whether Bixa orellana, which is found today as a wild plant, weed, or cultivated plant throughout the American tropics, was originally confined to either Central or South America.
A Dynamic Population of Weedy Rye 1
TLDR
The dramatic take-over by this interspecific derived population can be ascribed to a favorable climate and soil, and an unusual opportunity for continued introgression with diverse cultivars of rye, which may be applicable to rye breeding, new species (Triticale) production, and population genetics.
