A combination of meiotic pairing analysis and in situ hybridization (genomic in situ hybridization [GISH], multicolor GISH [mcGISH] and fluorescence in situ hybridization [FISH]) of five Triticum aestivum (Linnaeus, 1753) - Elytrigia elongata (Podpěra, 1902) (2n = 10x = 70) amphiploids was employed to investigate the genomic constitution and relationships between wheat and alien chromosomes. GI...

Forage kochia (Kochia prostrata ssp. virescens 'Immigrant' is native to the arid and semiarid regions of central Eurasia. It was introduced into the United States in 1966 as PI 314929 and released as a perennial forage shrub in 1984. Kochia americana is a perennial native to the United States, whereas Kochia scorparia is an introduced annual species that became a weed. To assess both the breedi...

The genus Avena L. (Poaceae) comprises a polyploid series ofdiploid, tetraploid and hexaploid species with a basic chromosome number of seven. Four genomes (A, B, C and D) have been identified based on comparative karyotyping (Rajhathy and Thomas 1974). The genomic in situ hybridizatjon (GISH) technique using A, eriantha's (CC) total DNA probe has been ibund to be very usefu1 fbr distinguishing...

Wild relatives of cultivated potato are used in breeding to increase the genetic diversity Solanum tuberosum (AAAA genome) varieties. Mexican allotetraploid species stoloniferum (AABB was for extreme resistance viruses and late blight. In this study, genomic situ hybridization (GISH) visualization introgression material B subgenome S. into genome backcross hybrids. The fertile hexaploid hybrid ...
