results 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 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...
متن کاملAnalysis of Fire Blight Shoot Infection Epidemics on Apple
Fire blight of apple (Malus × domestica Borkh.) can be found throughout the United States and many other countries and is a serious problem on trees of susceptible apple cultivars (9). Fire blight is caused by the bacterium Erwinia amylovora and occurs also on pear, quince, Rubus spp., and several other rosaceous hosts. The initial inoculum in an established orchard comes from overwintering can...
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 کاملRootstock Breeding for Stone Fruits
Over the last 20 years stone fruit rootstock development has begun shifting from seedling to clonal types, many of interspecific origin. Publicly funded breeding programs have produced most of these rootstocks due to the time, cost, and risk associated with their development; however, private industry is emerging as a significant contributor of many of the newer rootstocks. Particularly notewor...
