Inoculation techniques for evaluating resistance to Curtobacterium flaccumfaciens pv. flaccumfaciens in mungbean cultivars

Inoculation techniques for evaluating resistance to Curtobacterium flaccumfaciens pv.... Inoculation methods were developed for the purpose of screening a large collection of mungbean germplasm lines for resistance to tan spot caused by Curtobacteriumflaccumfaciens pv. flaccumfaczens. Stem prick and leaf infiltration inoculations were used to induce symptoms of vascular wilt and leaf scorch, respectively. There was variation in reaction to the two different tests within a range of eight cultivars tested. Cv. Green Diamond showed tolerance in both tests. However, there was little correlation between the two tests in disease reaction. Evidence indicates that the leaf scorch symptom is also due to water deprivation rather than to apoplastic pathogen invasion. A stem prick test suitable for screening mungbeans for tolerance to tan spot is described. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Australasian Plant Pathology Springer Journals

Abstract

Inoculation methods were developed for the purpose of screening a large collection of mungbean germplasm lines for resistance to tan spot caused by Curtobacteriumflaccumfaciens pv. flaccumfaczens. Stem prick and leaf infiltration inoculations were used to induce symptoms of vascular wilt and leaf scorch, respectively. There was variation in reaction to the two different tests within a range of eight cultivars tested. Cv. Green Diamond showed tolerance in both tests. However, there was little correlation between the two tests in disease reaction. Evidence indicates that the leaf scorch symptom is also due to water deprivation rather than to apoplastic pathogen invasion. A stem prick test suitable for screening mungbeans for tolerance to tan spot is described.
