Abstract
ピーマンの主要産地である宮崎県、鹿児島県、高知県、茨城県の線虫汚染ピーマン圃場50 カ所より土壌および被害根を採取し、これらよりネコブセンチュウの2 期幼虫および雌成虫を分離し、PCR-RFLP法によって各圃場10 ~ 25個体を1 頭ずつ同定した。その結果、同定された種は、1例を除きすべてサツマイモネコブセンチュウであった。また、上記の汚染圃場のうち31 圃場について、これらの線虫汚染土壌20 g を3 系統の線虫抵抗性トウガラシ(CM334、LS2341、PI322719)に接種したところ、6 圃場(19%)の汚染土壌において多数の根こぶおよび卵嚢が形成された。このことより、これらの圃場では抵抗性打破線虫が高い頻度で生息していると考えられた。
