A Dominant Gene for Resistance to Wheat Streak Mosaic Virus in Winter Wheat Line CO960293-2
Wheat streak mosaic (WSM), caused by Wheat streak mosaic virus (WSMV), is a devastating disease in wheat (Triticum aestivum L.) in the Great Plains of North America. Use of resistance is an effective and environmentally sound method to control the disease. In this study, six wheat genotypes were compared for their responses to WSMV infection under growth chamber conditions. The three resistant ...
متن کاملInheritance of Resistance to Stagonospora nodorum Leaf Blotch in Kansas Winter Wheat Cultivars
Stagonospora nodorum blotch, caused by Stagonospora nodorum (Berk.) Castellani & E.G. Germano (= Septoria nodorum (Berk.) Berk. in Berk. & Broome, teleomorph: Phaeosphaeria nodorum (E. Müller) Hedjaroude) can cause serious yield and quality losses of wheat (Triticum aestivum L.) in many countries worldwide (3,14,20). Yield losses caused by this disease have been reported as high as 40% in sever...
متن کاملPartial Resistance to Septoria Tritici Blotch (Mycosphaerella graminicola) in Wheat Cultivars Arina and Riband.
ABSTRACT Partial resistance to Septoria tritici blotch (STB) and its inheritance were investigated in a doubled-haploid population of a cross between cvs. Arina and Riband. The former has good partial resistance whereas the latter is susceptible. In adult plant trials in polytunnels, STB disease scores were negatively correlated with heading date. Resistance was not specific to any of the three...
متن کاملVernalisation Response of Some Winter Wheat Cultivars (Triticum aestivum L.)
For 17 cultivars of winter wheat (Triticum aestivum L.) different vernalisation and photoperiod responses were detected. The effect of photoperiod sensitivity was not significantly changed by vernalisation; different vernalisation responses were probably due to the presence of multiple alleles at Vrn loci. The delay in heading depended on the vernalisation deficit exponentially: y = parameter (...
متن کاملQTL mapping of partial resistance in winter wheat to Stagonospora nodorum blotch.
Stagonospora nodorum blotch is an important foliar and glume disease in cereals. Inheritance of resistance in wheat appears to be quantitative. To date, breeding of partially resistant cultivars has been the only effective way to combat this pathogen. The partial resistance components, namely length of incubation period, disease severity, and length of latent period, were evaluated on a populat...
