Selection methods in plant breeding based on mode of reproductionPlant breeders use different methods depending on the mode of reproduction of crops, which include: Self-fertilization, where pollen from a plant will fertilise reproductive cells or ovules of the same plant Cross-pollination, where pollen from one plant can only fertilize a different plant Asexual propagation (e.g. runners from strawberry plants) where the new plant is genetically identical to its parent Apomixis (self-cloning), where seeds are produced asexually and the new plant is genetically identical to its parent The mode of reproduction of a crop determines its genetic composition, which, in turn, is the deciding factor to develop suitable breeding and selection methods.
Minimum viable populationMinimum viable population (MVP) is a lower bound on the population of a species, such that it can survive in the wild. This term is commonly used in the fields of biology, ecology, and conservation biology. MVP refers to the smallest possible size at which a biological population can exist without facing extinction from natural disasters or demographic, environmental, or genetic stochasticity. The term "population" is defined as a group of interbreeding individuals in similar geographic area that undergo negligible gene flow with other groups of the species.
Vigna unguiculataVigna unguiculata, le niébé, est une espèce de plantes de la famille des Fabaceae et du genre Vigna originaire d'Afrique tropicale, dont plusieurs sous-espèces sont cultivées comme plantes alimentaires pour leurs graines, proches des haricots, ou pour leur gousses. C'est la principale légumineuse alimentaire d'Afrique tropicale, fournissant une source économique de protéines de grande qualité. Le Nigeria est le premier producteur mondial de niébé.
