Comparative mapping of the genes for brittle rachis in Triticum and Aegilops

Popis výsledku v původním jazyce

Using microsatellite markers, the homoeologous genes for brittle rachis were mapped in T. aestivum, T. turgidum L. and Ae. tauschii. Br2 was linked with the cetromeric marker, Xgwm32 (13.3 cM) on chromosome 3AS. Br3 on chromosome 3BS linked with the centromeric marker Xgwm72 (14.2 cM). Br1 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. The rachides of Ae. tauschii are brittle at every joint, so that the mature spike disarticulates into barrel shaped. The brittle rachis was determined by a dominant gene, Brt, which was linked to the centromeric marker, Xgdm72 (19.7 cM) on chromosome 3DS. A D genome introgression line, R-61, was derived from the cross Bet Hashita/Ae. tauschii, whose rachis disarticulated as a wedge type. The gene for brittle rachis of R-61(tentatively named as Br61) was on chromosome 3DS linked with the centromeric marker, Xgdm72 (27.5 cM).
