Inheritance of fire blight resistance in Asian Pyrus species
Since several Asian pear species are considered to be potential source of fire blight resistance, we crossed ‘Doyenné du Comice’, the susceptible European cultivar, with four Asian pear species. The aim of the study was to establish the level of resistance of each genotype and the mode of transmission of fire blight resistance to each F1 full-sib progeny. The best sources of resistance were P. ...
متن کاملInheritance of resistance to bacterial blight in 21 cultivars of rice.
ABSTRACT Genetic analysis for resistance to bacterial blight (Xanthomonas oryzae pv. oryzae) of 21 rice (Oryza sativa L.) cultivars was carried out. These cultivars were divided into two groups based on their reactions to Philippine races of bacterial blight. Cultivars of group 1 were resistant to race 1 and those of group 2 were susceptible to race 1 but resistant to race 2. All the cultivars ...
متن کاملresults of screening on 89 apple cultivars for fire blight resistance using usda system in karaj conditions
fire blight disease caused by erwinia amylovora is a destructive disease of pome fruits including apple worldwide. use of resistant cultivars is the most efficient method of disease control. in the present research, we investigated genetic resistance of 89 local and imported commercial apple cultivars in natural contaminated conditions to the bacterial disease using beltsville scoring system (u...
متن کاملDevelopment of the First Cisgenic Apple with Increased Resistance to Fire Blight
The generation and selection of novel fire blight resistant apple genotypes would greatly improve the management of this devastating disease, caused by Erwinia amylovora. Such resistant genotypes are currently developed by conventional breeding, but novel breeding technologies including cisgenesis could be an alternative approach. A cisgenic apple line C44.4.146 was regenerated using the cisgen...
متن کاملUsing Functional Genomics to Identify Molecular Markers for Fire Blight Resistance (Erwinia Amylovora) in Apple (Malus)
Fire blight, caused by Erwinia amylovora (Ea), is a destructive disease of Malus (apple), Pyrus (pear) and some woody ornamentals in the rose family (Rosaceae). The goal of this project is to use a functional genomics approach to develop tools to breed fire blight resistant apples. Suppression subtractive hybridization (SSH) and cDNA-AFLP analysis were used to identify 650 expressed sequence ta...
