A study was initiated in 2001at four locations in western Canada to investigate an integrated approach to managing wild oat, the region’s worst weed. The study examined the effects of combining semidwarf or tall barley cultivars with normal or twice-normal barley seeding rates in either continuous barley or a barley–canola–barley–field pea–barley rotation. Herbicides were applied at 25, 50, and...

Visible and near infrared (Vis/NIR) spectroscopy was investigated for the fast analysis of superoxide dismutase (SOD) activity in barley (Hordeum vulgare L.) leaves. Seven different spectra preprocessing methods were compared. Four regression methods were used for comparison of prediction performance, including partial least squares (PLS), multiple linear regression (MLR), least squares-support...

Barley powdery mildew, caused by the pathogen Blumeria graminis f. sp. hordei is an important disease of barley (Hordeum vulgare L.). The random amplified polymorphic DNA (RAPD) method was used to detect DNA polymorphism among 7 Pallas near-isogenic lines (NILs) carrying Mla3, Mla12, Mlk, Mlp, Mlat, Mlg and MlLa genes for resistance to B. graminis f. sp. hordei. From among 500 random 10-mer pri...

The domestication of cultivated barley has been used as a model system for studying the origins and early spread of agrarian culture. Our previous results indicated that the Tibetan Plateau and its vicinity is one of the centers of domestication of cultivated barley. Here we reveal multiple origins of domesticated barley using transcriptome profiling of cultivated and wild-barley genotypes. App...

We investigated the suitability of 11 diets as culture media for the psocids Lepinotus reticulatus Enderlein (Psocoptera: Trogiidae) and Liposcelis entomophila (Enderlein) (Psocoptera: Liposcelididae). The culture media comprised six diets made of plain cereals, namely, wheat (Triticum aestivum L.), corn (Zea mays L.), milo Sorghum bicolor (L.), barley (Hordeum vulgare L.), oats (Avena sativa L...
