[PDF][PDF] Virulence frequencies of Xanthomonas oryzae pv. oryzae on different sets of rice differentials under Punjab agro-ecological zones

MS Hunjan, PP Singh, JS Lore - Indian Phytopathology, 2014 - epubs.icar.org.in
Virulence frequencies on a particular differential were calculated as the ratio of virulent
isolates of Xanthomonas oryzae pv. oryzae to the number of total isolates tested. Numerical
data pertaining to disease score (0-9) was analysed by virulence analysis tool. In this study,
virulence frequencies to the resistance genes present in the standard international
differentials including near isogenic lines (NILs) and local rice cultivars, ranged between 0–
1 (representing zero to 100 per cent). None of the single gene was found to be effective …
