| Definition | Kinchaku and its resistant progeny showed no visible disease symptoms macroscopically or microscopically. Recently, isolates (strains) of V. nashicola collected from cultivated and wild pears in Japan were categorized by inoculation test into three races (Ishii et al. 2002). Kinchaku showed resistance to all three races, suggesting that Vnk may be race-nonspecific (Ishii et al. 2002), or that the specific virulent race has not yet been detected. It was also shown that race-specific resistance genes exist in some pear cultivars (Ishii et al. 2002). |
