Abstract
00Ar134-1 is an intergeneric spring wheat line derived from Elymus repens (quack grass). The line was developed as a potentially new source of resistance to Fusarium head blight (FHB) in wheat. 00Ar134-1 is resistant to Fusarium head blight as well as leaf rust, stem rust, and common bunt. Although lower yielding and taller than commercial cultivars, this line is of similar maturity and kernel weight. 00Ar134-1 can potentially be used as a resistant parent for improving Fusarium head blight resistance in common wheat.
Highlights
Fusarium head blight (FHB), mainly caused by Fusarium graminearum Schwabe
The disease results in shrivelled, light-weight, and chalky white Fusarium damaged kernels which contain mycotoxins such as deoxynivalenol (DON) and nivalenol (NIV)
The line 00Ar134-1 is a spring wheat line of intergeneric origin developed as a resistant source to FHB
Summary
Fusarium head blight (FHB), mainly caused by Fusarium graminearum Schwabe Mots-clés : Elymus repens, lignée intergénérique, 00Ar134-1, brûlure de l’épie causée par Fusarium, blé, gale. The line ‘00Ar-134-1’ was one of the lines derived from near-homozygous BC1F7 progeny and was subsequently evaluated for agronomic and disease resistance traits for six years (2009–2014) at Saskatoon, SK and Carman, MB. The line has been tested for agronomic and disease resistance traits and compared with mainly Canada Western Red Spring (CWRS) wheat cultivar checks from 2009–2014 (Tables 1–3).
