Characterization of Pratylenchus penetrans from Ten Geographically Isolated Populations Based on Their Reaction on Potato

Characterization of Pratylenchus penetrans from Ten Geographically Isolated Populations Based on Their Reaction on Potato

Journal of Nematology 28(4): 520-526

Single female cultures of Pratylenchus penetrans were established from soil and root samples collected from 10 geographically isolated locations in North America. The resultant isolates were used to evaluate nematode egression from and multiplication on roots of potato clones to distinguish intraspecific differences among isolates. The 10 nematode isolates were statistically separated into four groups based on percentage of nematodes that egressed from the P. penetrans resistant potato clone L118-2. The Cornell (CR), Wisconsin (WI), Long Island (LI), and Adirondack (AD) isolates, selected as representative isolates of each of the four groups, exhibited 53%, 39%, 25%, and 10% egression from L118-2, respectively. Reproduction of these four isolates was measured on three potato cultivars (Russet Burbank, Butte, and Hudson) and two breeding lines (NY85 and L118-2). The L1 and AD isolates reproduced well on all five potato clones. The CR isolate reproduced well on Russet Burbank and NY85 but significantly less on Butte, Hudson, and LI 18-2. Reproduction of the WI isolate was less than the L1 and AD isolates but more than the CR isolate on all potato clones tested except Russet Burbank. Reproduction Of the WI isolate on Russet Burbank was less than the other three isolates. Based on these results, four distinct intraspecific variants of P. penetrans are proposed: Cornell, Wisconsin, Long Island, and Adirondack.
