Ellucidation of RPG4/RPG5-Mediated Resistance Against Wheat Stem Rust in Barley
(North Dakota State University, 2015)Wheat stem rust, caused by Puccinia graminis f. sp. tritici (Pgt), is a major threat to barley and caused devastating reductions in yield and economic losses. The barley line Q21861 was identified as the best source of ... -
Evaluating Chemical Seed Treatments for Fusarium Root Rot Control in Dry Beans and Field Peas
(North Dakota State University, 2014)This study evaluated commercially available seed treatment products for their ability to control Fusarium solani and F. avenaceum, causal agents of root rot in dry edible bean and field peas, respectively, through in-vitro, ... -
Evaluation of Field Pea Varieties for Resistance to Fusarium Root Rot Pathogens
(North Dakota State University, 2017)Fusarium root rot is one of the most important diseases of pulse crops, with numerous Fusarium spp. comprising the disease complex. Fusarium solani and F. avenaceum have been reported to be major pathogens in the pea root ... -
Evaluation of Genetic Resistance to Common Bacterial Blight in Dry Edible Bean
(North Dakota State University, 2015)Common bacterial blight (CBB) is an economically important disease of dry bean worldwide caused by Xanthomonas axonopodis pv. phaseoli, (Xap). The objectives of this research were to determine the frequency of CBB resistance ... -
Evaluation of Winter Wheat Germplasm for Resistance to Stripe Rust and Leaf Rust
(North Dakota State University, 2014)Wheat leaf rust, caused by Puccinia triticina (Pt), and wheat stripe rust caused by P. striiformis f. sp. tritici (Pst) are important foliar diseases of wheat (Triticum aestivum L.) worldwide. Breeding for disease resistance ... -
