Node inoculation: A quick and easy technique to screen pigeonpea for resistance to Phytophthora blight uri icon

abstract

  • The petiole on pigeonpea was removed for easy,precise inoculation of node with Phytophthora drechslerif. sp. cajani. After node inoculation, 96.0% plants wereinfected compared with 89.0% after stem-cut inoculation.Among various nodes inoculated on 30-day-old plants, the5th node had the greatest relative susceptibility (90.0%), followedby the 3rd node (78.0%). This technique was validatedon different cultivars (ICP 7119, Bahar, MA 6 and MAL13), and 586 lines were successfully screened in the field,confirming the rapidity and effectiveness of the techniquefor resistance screening
