The synaptic behaviour of Triticum turgidum with variable doses of the Ph1 locus
Cultivated wheat Triticum turgidum is an allotetraploid (AABB) with diploid-like behaviour at metaphase I. This behaviour is mainly influenced by the action of the Ph1 locus. To study the effect of Ph1 on chromos...

Preferential occurrence of wheat-rye meiotic pairing between chromosomes of homoeologous group 1
Wheat-rye homoeologous pairing in both ABRR and (0–7)A(0–7)BRR plants takes place preferentially between homoeologous chromosomes of group 1. This suggests either a much greater affinity between wheat and rye ...
