Identification of PCH1 Eyespot Resistance Gene in the Collection of Wheat Lines (Triticum Aestivum L.)

摘要

Identification of PCH1 Eyespot Resistance Gene in the Collection of Wheat Lines (Triticum Aestivum L.)Endopeptidase marker EpD1b and STS marker XustSSR2001-7DL are closely linked to very effective eyespot resistance gene Pch1. Because of this, the aim of this study was to compare the results obtained under lab conditions using such markers with the results obtained under field conditions. 134 wheat breeding lines and Triticum aestivum L. var. Randevous used as a eyespot resistance control were analized. The combination of three methods allowed to select eight completely resistant or high resistant lines, that could be used in following breeding processes. Results obtained using endopeptidase and STS markers in 100% correlate with the phenotyping scoring.
