Efficient Assessment and Large-Scale Conservation of Intra-Varietal Diversity o...

There are thousands of ancient grapevine varieties in Europe, each one having a high level of intra-varietal diversity with regard to important economic traits (yield, soluble solids content, acidity, anthocyanins, and others). However, this potential has become exposed to a process of genetic erosion since the middle of the last century. The main objective of this work is to present experimental strategies for...

Pervasive hybridization with local wild relatives in Western European grapevine...

Grapevine (Vitis vinifera L.) diversity richness results from a complex domestication history over multiple historical periods. Here, we used whole-genome resequencing to elucidate different aspects of its recent evolutionary history. Our results support a model in which a central domestication event in grapevine was followed by postdomestication hybridization with local wild genotypes, leading to the presence ...

As castas de videira autóctones, raízes do vinho e da cultura mediterrânica: co...

Portugal herdou do passado um parque de castas autóctones invulgarmente elevado, quando comparado com os de outros grandes países vitivinícolas da orla mediterrânica, centro de origem e de diversidade da videira: cerca de 250 castas, isto é, um número da mesma ordem de grandeza dos de Espanha, França e Itália, mas mais significativo quando confrontado com a menor superfície do país

Selecting Aragonez genotypes able to outplay climate change-driven abiotic stress

High temperatures and extreme drought are increasingly more frequent in Portugal, which represents a strong threat to viticulture in certain regions of the country. These multifactorial abiotic stresses are threatening viticultural areas worldwide, and the problem can hardly be overcome only by changing cultural practices. This scenario has raised a major challenge for plant scientists to find ways to adapt exi...

Conservação e utilização da diversidade intravarietal da videira: situação atua...

A conservação e utilização da variabilidade intravarietal tem sido conduzida por parte dos intervenientes atrás referidos de acordo com uma estratégia metodológica coerente e inovadora de modo a fazer face aos objetivos atuais e futuros da vitivinicultura, respondendo desde logo a três questões fundamentais: saber o que conservar, como conservar e como utilizar a diversidade e de empresas vitivinícolas, dando o...

Uma nova abordagem na avaliacao da interacao genotipo×ambiente em especies lenh...

Neste trabalho estuda-se a interacao genotipo×ambiente (G×E) numa especie perene. Neste contexto, fazem-se avaliacoes num dado local na mesma unidade experimental ao longo de anos consecutivos. Ou seja, os erros aleatorios associados a duas quaisquer observacoes na mesma unidade experimental nao sao independentes. Ajustam-se, aos dados de rendimento, modelos mistos com matrizes de covariancias do vector dos err...
