Book Synopsis Assessment of Genetic Resistance to Strawbreaker Foot-rot (Pseudocercosporella Herpotrichoides) in Selected Winter Wheat (Triticum Aestivum L.) Cultivars by : Andrés Encinas-Mungarro

Cultivars written by Andrés Encinas-Mungarro and published by . This book was released on 1991 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strawbreaker foot-rot is a major limiting factor to cost efficient winter wheat production in the Pacific Northwest. Development of resistant cultivars has been hindered by the lack of adequate levels of genetic resistance and screening techniques which can consistently detect desired genotypes. Studies were conducted to determine if the reported strawbreaker foot-rot resistance of the cultivar "Rendezvous" is effective on isolates of Pseudocercosporella herpotrichoides found in the Pacific Northwest. Protected, naturally infected and artificially inoculated treatments were employed to determine the level of resistance of 10 cultivars including Rendezvous. Different concentrations of inoculum and stages of development were also used to determine if observations on leaf sheath penetration of seedlings obtained in the greenhouse were related to disease severity index readings taken in the field for selected cultivars. In addition, the nature of inheritance of strawbreaker foot-rot was studied in two crosses involving Rendezvous. Experiments were conducted at three locations and over two years at one location. Despite cultivar x treatment interaction, consistent levels of infection were observed in all experiments at each location. Significant differences were found for treatments and cultivars for most attributes. Yield losses, including the components of yield spikes per square meter, 1000 kernel weight, and kernel number per spike were proportional to the severity of the disease. Losses were greater when lodging occurred, which was also associated with disease severity. However, even in the absence of lodging losses were recorded in the naturally and artificially inoculated plots. Traits measured involving Rendezvous and Vpm/Mos 95//*2Hill were only slightly influenced by the treatments. Under greenhouse conditions, it was possible to distinguish the level of resistance of Rendezvous from susceptible cultivars at concentrations of 100 spores/ml, two weeks after inoculation at the seedling stage. Leaf sheath penetration of seedlings was found to be closely associated with the disease severity index obtained under field conditions. Generation means analysis performed in crosses involving Rendezvous indicated that additive and additive x additive gene action were responsible for most of the genetic variability associated with resistance. Narrow-sense heritability estimates also confirmed these fmdings. It would appear that Rendezvous has at least two major genes for resistance to strawbreaker foot-rot.

Book excerpt: Excerpt from Influence of Climatological Factors in the Development of Cercosporella Foot Rot of Winter Wheat In the course of this experiment it became evident that the disease reactions in the different chambers-were scarcely comparable because the plants in chamber no. 1, which was kept out of doors, developed so much slower than those in the other chambers.

Book Synopsis Modern Assays for Plant Pathogenic Fungi by : A. Schots
Download or read book Modern Assays for Plant Pathogenic Fungi written by A. Schots and published by Oxford University Press, USA. This book was released on 1994 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: This practically-oriented book provides both the theoretical background and step-by-step protocols for methods employing new technologies for the detection of plant pathogenic fungi. Methods have recently been developed which can be undertaken on a wide scale, with large numbers of samples, and which are simple to use, highly sensitive and very specific. Hybridoma and DNA technologies provide the basis of such assays and include the use of monoclonal antibodies, the polymerase chain reaction (PCR) and DNA hybridization. The book is based on papers presented at a conference held in Oxford in March 1993, under the BRIDGE-COST-88 program developed by the Commission of the European Communities. A wide range of fungi, which are pathogens of a variety of crop and ornamental plants, is covered and the book is aimed at postgraduate students and research workers in mycology and plant pathology, including those involved in routine testing of plants for quarantine or other purposes
