Hidden genetic variance and residual allogamy contribute to increase the adaptive potential of selfing populations

, 2019
Abstract Standing genetic variation is considered a major contributor to the adaptive potential of species. The low heritable genetic variation observed in self-fertilising populations has led to the hypothesis that species with this mating system would be less likely to adapt.

Construction of two genetic linkage maps in cultivated tetraploid alfalfa (Medicago sativa) using microsatellite and AFLP markers

BMC Plant Biology, 2003
Background Alfalfa (Medicago sativa) is a major forage crop. The genetic progress is slow in this legume species because of its autotetraploidy and allogamy. The genetic structure of this species makes the construction of genetic maps difficult. To reach

RICE (Oryza sativa L.) ALLOGAMY AND RELATIONSHIP WITH AGRONOMIC TRAITS

, 2007
A produção de sementes híbridas de arroz, utilizando a técnica chinesa, requer uma grande quantidade de mão-de-obra e é cara. Alternativas para aumentar a taxa de polinização cruzada podem ajudar a reduzir tal custo. A Embrapa Arroz e Feijão desenvolve um projeto de produção de híbridos através da transferência de caracteres alogâmicos (comprimento de ...
