Název v původním jazyce

The genes on homoeologous group 3 chromosomes determine brittle rachides in Triticum and Aegilops

Popis výsledku v původním jazyce

Using microsatellite markers, the homoeologous genes for brittle rachis were mapped in hexaploid wheat (Triticum aestivum L.), durum wheat (Triticum durum Desf.) and Aegilops tauschii Coss. On chromosome 3AS, the gene for brittle rachis Br2 was linked with the centromeric marker Xgwm32 in the distance of 13.3 cM. Br3 was located on chromosome 3BS and linked with the centromeric marker Xgwm72 (14.2 cM). Br1 was located on chromosome 3DS. The distance from the centromeric marker Xgdm72 was 23.6 cM. The loci Br1, Br2 and Br3 determine disarticulation of rachides above the junction of the rachilla with the rachis such that a fragment of rachis is attached below each spikelet. The rachides of Ae. tauschii are brittle at every joint, so that the mature spikedisarticulates into barrel type. The brittle rachis was determined by a dominant gene Br, which was linked to the centromeric marker Xgdm72 (19.7 cM) on chromosome 3DS.
