Asadi, Ghorbanali ; Ghorbani, Reza ; Karimi, Javad ; Bagheri, Alireza ; Müller-Schärer, Heinz

In: Weed Technology, 2013, vol. 27, no. 2, p. 405–411

This study determined the potential of the tortoise beetle (Coleoptera: Chrysomelidae) to control Canada thistle (Asteraceae) in Iran. Genetic analysis of the tortoise beetle, based on mitochondrial DNA, confirmed the presence of the species in Iran. A field experiment using five insect densities (0 to 20 larvae plant−1) showed a positive correlation between the number of larvae transferred and...

Search for evidence of introgression of wheat (Triticum aestivum L.) traits into sea barley (Hordeum marinum s.str. Huds.) and bearded wheatgrass (Elymus caninus L.) in central and northern Europe, using isozymes, RAPD and microsatellite markers

Guadagnuolo, Roberto ; Savova-Bianchi, D. ; Keller-Senften, J. ; Felber, François

In: TAG Theoretical and Applied Genetics, 2001, vol. 103, no. 2-3, p. 191-196

Seeds of English and Austrian populations of bearded wheatgrass (Elymus caninus L.) and sea barley (Hordeum marinum Huds.) growing in the vicinity of wheat (Triticum aestivum L.) fields were collected in order to search for evidence of the introgression of wheat traits into these wild relatives. Seeds were sown and plants grown for subsequent analyses using morphological and...

Gene flow from wheat (Triticum aestivum L.) to jointed goatgrass (Aegilops cylindrica Host.), as revealed by RAPD and microsatellite markers

Guadagnuolo, Roberto ; Savova-Bianchi, D. ; Felber, François

In: TAG Theoretical and Applied Genetics, 2001, vol. 103, no. 1, p. 1-8

In order to estimate the potential of gene flow between wheat (Triticum æstivum L.) and jointed goatgrass (Aegilops cylindrica Host.), we carried out mixed pollinations in experimental and natural conditions. A set of species-specific RAPD (random amplified polymorphic DNA) and microsatellite markers were used to detect the presence of parental markers in the progeny of the plants...
