Detection of homoeologous chiasma formation in Triticum durum × Thinopyrum bessarabicum hybrids using genomic in situ hybridization

Chromosome identification by new molecular markers and genomic in situ hybridization in the Triticum-Secale-Thinopyrum trigeneric hybrids.

It is very important to use chromosome-specific markers for identifying alien chromosomes in advanced generations of distant hybridization. The chromosome-specific markers of rye and Thinopyrum elongatum, as well as genomic in situ hybridization, were used to identify the alien chromosomes in eight lines that were derived from the crossing between Triticum trititrigia (AABBEE) and triticale (AA...

Synthesis and characterization of advanced durum wheat hybrids and addition lines with thinopyrum chromosomes.

Durum wheat (Triticum turgidum L., 2n = 4x = 28; AABB genomes) is a natural hybrid-an allotetraploid between 2 wild species, Triticum urartu Tumanian (AA genome) and Aegilops speltoides Tausch (BB genome). Even at the allotetraploid level, durum wheat can tolerate chromosomal imbalance, for example, addition of alien chromosome 1E of diploid wheatgrass, Lophopyrum elongatum. Therefore, one way ...

The Choromosomal Assesment of Salt Tolerant Substituted Tritipyrum Using Genomic Fluorescentin situ Hybridization (FISH)

can tritipyrum, a new salt tolerant potential amphiploid, be a successful cereal like triticale?

soil affected by salt (nacl) is a major problem worldwide and in areas with potential agriculture; lands in many countries are not enough to support crop production. the development of salt tolerant cultivars would be enhanced by better understanding of the genetic control of tolerance to salt stress. a new cereal, tritipyrum, a range of amphiploids between triticum spp. and thinopyrum spp....

Establishment of the genomic in situ hybridization (GISH) technique for analysis in interspecific hybrids of Passiflora.

The genomic in situ hybridization (GISH) technique was applied to Passiflora interspecific F1 HD13-133 hybrids (Passiflora sublanceolata x Passiflora foetida) and HD15-101 (Passiflora gardineri x Passiflora gibertii), and the backcrossed hybrids (BC1) HD18-106 and HD18-113 (Passiflora sublanceolata x HD13-133). GISH was performed using genomic probes prepared with the DNA from the paternal geni...
