Dissecting the genetic basis of wheat blast resistance in the Brazilian wheat cultivar BR 18-Terena.

ABSTRACT:

Background

Wheat blast, caused by Magnaporthe oryzae Triticum (MoT) pathotype, is a global threat to wheat (Triticum aestivum L.) production. Few blast resistance (R) genes have been identified to date, therefore assessing potential sources of resistance in wheat is important. The Brazilian wheat cultivar BR 18-Terena is considered one of the best sources of resistance to blast and has been widely used in Brazilian breeding programmes, however the underlying genetics of this resistance are unknown.

Results

BR 18-Terena was used as the common parent in the development of two recombinant inbred line (RIL) F₆ populations with the Brazilian cultivars Anahuac 75 and BRS 179. Populations were phenotyped for resistance at the seedling and heading stage using the sequence
