Partial resistance to neck blast influenced by stage of panicle development and rice genotype

  title={Partial resistance to neck blast influenced by stage of panicle development and rice genotype},
  author={E. Roumen},
SummaryNeck nodes of eight rice genotypes were inoculated with a virulent isolate of the blast pathogen at four slightly different, increasingly older stages of panicle development shortly after flowering. Resistance to infection as well as resistance to growth of the pathogen after infection was assessed. Significant differences between genotypes were found for both components of resistance. Resistance to growth of the pathogen sharply increased with aging of the neck node as was indicated by… Expand

Variability in Aggressiveness of Rice Blast (Magnaporthe oryzae) Isolates Originating from Rice Leaves and Necks: A Case of Pathogen Specialization?
Testing the hypothesis of adaptation of M. oryzae isolates to the type of organ they infect suggested that the more aggressive isolates involved in epidemics on leaves during the vegetative stage of the crop cycle have a higher probability to infect necks, and that a population shift may occur during disease transmission from leaves to necks.

Response to selection for high and low partial resistance to leaf blast in F2 populations of three rice crosses
The results indicated that the relatively low infection efficiency in IR36 and IR64 is oligo- or polygenically controlled, which is probably much higher if replicated tests could be made, and better results are therefore expected if selection among F3 lines is carried out. Expand
Identification of blast resistance genes in 358 rice germplasms (Oryza sativa L.) using functional molecular markers
Insight is provided into the distribution of the 13 major blast R genes in the tested Chinese rice germplasm resources, which will serve as a basis for developing rice blast resistant varieties. Expand
Genetic analysis of partial resistance to black stem (Phoma macdonaldii) in sunflower as measured by a seedling test
The cross between M6-54-1 and ENSAT-R5 genotypes, which are the best general combiners for MP8 and MP10, respectively, could be of value in improving black stem partial resistance to these P. macdonaldii isolates. Expand
Fine mapping of a panicle blast resistance gene Pb-bd1 in Japonica landrace Bodao and its application in rice breeding
Two QTLs, qPb11–1(Pb-bd1) andqPb6–1 conferring panicle blast resistance, were identified from japonica landrace Bodao and Suyunuo, indicating that Pb-BD1 would be useful gene source in panicle Blast resistance breeding. Expand
Use of two PGPR strains in the integrated management of blast disease in rice (Oryza sativa) in Southern Spain
A direct relation between protection mediated by the PGPR and the increase in rice productivity and quality was found, suggesting a biocontrol mediated protection. Expand
A genome-wide meta-analysis of rice blast resistance genes and quantitative trait loci provides new insights into partial and complete resistance.
A review of bibliographic references identified 85 blast resistance genes and approximately 350 QTL, which are mapped on the rice genome, which provide a useful update on blast Resistance genes as well as new insights to help formulate hypotheses about the molecular function of blast QTL. Expand
The effect of temperature and relative humidity on the airbone concentration of Pyricularia oryzae spores and the development of rice blast in southern Spain.
Assessing the airborne concentration of P. oryzae could help in understanding the population dynamics of this pathogen and the peak spore concentration in August could be used to forecast panicle blast. Expand
Quantitative trait loci analysis suggests that partial resistance to rice blast is mostly determined by race–specific interactions
The results support the hypothesis that partial resistance genes might be defeated major genes, with residual effectiveness and race specificity, and the majority of QTL detected are race-specific. Expand

Rice blast caused by Magnaporthe oryzae poses a major threat to rice production worldwide. The utilization of host resistance (R) genes is considered to be the most effective and economic means toExpand


Effect of leaf age on components of partial resistance in rice to leaf blast
Genotypes with leaves that became highly resistant soon after appearance expressed higher levels of partial resistance in the field, and this factor was closely related to the period that leaves remained susceptible after appearance. Expand
Leaf age related partial resistance to Pyricularia oryzae in tropical lowland rice cultivars as measured by the number of sporulating lesions.
To study the effects of leaf age on resistance, plants of four rice cultivars were inoculated with a virulent isolate of Pyricularia oryzae, and susceptibility of leaves declined rapidly with increasing leaf age, but resistance in leaves rapidly increased with age. Expand
Differential Susceptibility of Rice Leaves and Panicles to Piricularia Oryzae
Abstract : Greenhouse tests of differential susceptibility of rice (var. Zenith) seedlings and panicles to Piricularia oryzae indicated that seedlings inoculated with race 11 (IA-2) were highlyExpand
Leaf and neck blast resistance in tropical lowlande rice cultivars
The classification of neck blast resistance of intermediate and susceptible lines varied between trials, mostly due to differences in flowering date. The mean leaf blast values from the miniplotExpand
