Characterization of resistance to Pratylenchus thornei (Nematoda) in wheat (Triticum aestivum): attraction, penetration, motility, and reproduction.

Lines from a cross between two wheat (Triticum aestivum) cultivars with contrasting resistance phenotypes to Pratylenchus thornei (Nematoda) were investigated to determine the stage at which resistance occurs. Host resistance was examined at nematode attraction to and penetration of roots and nematode motility, maturation, and reproduction within roots. There was no significant difference in the rate at which P.
