Abstract

Pratylenchus thornei densities were monitored in field plots of two winterwheat cultivars in a dry farming area of southern Spain. Samples were taken fortnightly during the wheat-growing season and from the following dry fallow. Under durum wheat cv. 'Donpedro', nematode densities decreased thornei increased for 5 to 6 months and then were maintained or slightly decreased thereafter, surviving the summer dry fallow in an anhydrobiotic state (78.2% and 85.3% survival in soil and roots, respectively). Under durum wheat cv. 'Donpedro', nematode densities decreased over the growing season, although densities within the roots increased during the first 2 months of the wheat-growing period, indicating that nematodes could penetrate the roots ofthis cultivar but were unable to reproduce. These observations suggest resistance of wheat cv. Donpedro to P. thornei.
