First Report of Ascochyta Blight of Spotted Locoweed (Astragalus lentiginosus) Caused by Ascochyta sp. in Idaho

Loco intoxication: indolizidine alkaloids of spotted locoweed (Astragalus lentiginosus).

Grazing of spotted locoweed (Astragalus lentiginosus) by cattle and horses in Arizona.

Spotted locoweed (Astragalus lentiginosus var. diphysus) is a toxic, perennial plant that may, if sufficient precipitation occurs, dominate the herbaceous vegetation of pinyon-juniper woodlands on the Colorado Plateau. Six cow/calf pairs and four horses grazed a 20-ha pasture with dense patches of locoweed in eastern Arizona during spring 1998. Locoweed density was 0.7 plants/m2 in the pasture....

Fetotoxicity of Astragalus lentiginosus (Locoweed) in Spanish Goats

Locoweed species—Astragalus and Oxytropis spp. that contain the indolizidine alkaloid swainsonine— are widely distributed on rangelands in North and South America, Mexico, China, and other rangelands throughout the world. Other range plant species including Sida spp. (Seitz et al. 2005), Ipomoea spp. (Damir et al. 1987), and Swainsona spp. (Laws and Anson 1968) from Brazil, Africa, and Australi...

Genetical Analysis of Ascochyta Blight Resistance in Chickpea

Ascochyta blight, caused by Ascochyta rabiei (Pass.) Lab. is a devastating disease of chickpea (Cicer arietinum L.) worldwide. Available genetic variation for Ascochyta blight resistance in genus Cicer has prompted interest in the development and use of resistant cultivars that can be sown in autumn and, to increase seed yield in chickpea. Understanding the mode of inheritance of resistance to ...

genetics of ascochyta blight resistance in chickpea

available genetic variation for ascochyta blight resistance in genus cicer has prompted interest in the development and use of autumn sown resistant chickpea cultivars. a thorough understanding of the mode of inheritance of resistance to ascochyta blight in chickpea would assist the breeding efforts. in order to determine the number of genes, as well as to evaluate heritability and action of ge...
