The ability of the wheat Lr34 multipathogen resistance gene (Lr34res) to function across a wide taxonomic boundary was investigated in transgenic Sorghum bicolor. Increased resistance to sorghum rust and anthracnose disease symptoms following infection with the biotrophic pathogen Puccinia purpurea and the hemibiotroph Colletotrichum sublineolum, respectively, occurred in transgenic plants expr...
Leaf rust caused by Puccinia triticina Eriks. (Pt) is one of the most devastating fungal pathogens affecting wheat (Triticum aestivum L.) production worldwide. Deployment resistant cultivars environmentally friendly approach to control disease. In this study, thirty-seven lines from Hubei and Shaanxi provinces in China were evaluated for seedling resistance greenhouse using eighteen Pt races. T...
Juchi F2000, Náhuatl F2000 y Tlaxcala son variedades de trigo harinero recientemente liberadas para siembras temporal o secano en México. La roya la hoja del causada por Puccinia triticina E. afecta producción este cereal forma continua, lo que; el mejoramiento genético resistencia a esta enfermedad ha sido método más eficiente su control. Con fin determinar genética éstas se cruzaron con varie...
The objective of this study was to assess diversity for stem rust and stripe resistance in an international wheat screening nursery under greenhouse conditions using pathotypes with known avirulence/ virulence profiles. A set 95 entries collected from material generated by staff the International Maize Wheat Improvement Centre (CIMMYT) tested against seven Australian Pgt five Pst through artifi...
Leaf rust is amongst major biotic constraints of wheat (Triticum aestivum L.) having ability to cause substantial yield reductions worldwide. A continuous exploration for novel sources resistance pre-requisite its management. Objectives study were conduct evaluation 112 Pakistani landraces and 48 advanced lines/ cultivars at seedling stage with total 10 virulent pathotypes leaf rust, 3 from Pak...
Wheat leaf rust is an important disease worldwide. Growing resistant cultivars is an effective means to control the disease. In the present study, 244 recombinant inbred lines from Zhou 8425B/Chinese Spring cross were phenotyped for leaf rust severities during the 2011-2012, 2012-2013, 2013-2014, and 2014-2015 cropping seasons at Baoding, Hebei province, and 2012-2013 and 2013-2014 cropping sea...
ABSTRACT Canadian wheat cvs. Pasqua and AC Taber were examined genetically to determine the number and identity of stem rust resistance genes in both. The two cultivars were crossed with stem rust susceptible line RL6071, and sets of random F(6) lines were developed from each cross. The F(6) lines, parents, and tester lines with single stem rust resistance genes were grown in a field rust nurse...
