Genetic Relationships Among Portuguese Cultivated and Wild Vitis vinifera L. Germplasm

Genetic structure and differentiation in cultivated grape, Vitis vinifera L.

222 cultivated (Vitis vinifera) and 22 wild (V. vinifera ssp. sylvestris) grape accessions were analysed for genetic diversity and differentiation at eight microsatellite loci. A total of 94 alleles were detected, with extensive polymorphism among the accessions. Multivariate relationships among accessions revealed 16 genetic groups structured into three clusters, supporting the classical eco-g...

Genetic relationships among local Vitis vinifera cultivars from Campania (Italy)

A total of 114 accessions putatively corresponding to 69 local grape cultivars from Campania (Southern Italy) were analysed with 8 microsatellite markers (VVS2, VVMD5, VVMD7, VVMD25, VVMD27, VVMD31, VrZAG62 and VrZAG79) in order to evaluate their genetic diversity and relationships. According to their unique genotype at SSR loci finally 56 varieties were found. Interesting cases of synonymy, i....

Chloroplast genome diversity in Portuguese grapevine (Vitis vinifera L.) cultivars.

Grapevine chloroplast (cp) DNA diversity was analysed for the first time through amplification and digestion of fragments of the large single copy (LSC) region by polymerase chain reaction-restriction fragment length polymorphism methodology and also by amplification of three microsatellite loci, previously described as polymorphic in grapevine. Thirty-eight grapevine cultivars collected mainly...

Genetic Variation and Relationships among Cultivated, Wild, and Semiwild Soybean

Fukuda (1933) proposed that G. gracilis is an intermediate evolutionary type between G. soja to G. max, but Some annual Glycine accessions are intermediate between the Hymowitz (1970) suggested that G. gracilis is a hybridstandard phenotypes of Glycine max (L.) Merr. and Glycine soja Sieb. & Zucc. and have been labeled semiwild. Few studies have ization product of G. max and G. soja. The latter...
