Monitoring Pratylenchus thornei densities in soil and roots under resistant (Triticum turgidum durum) and susceptible (Triticum aestivum) wheat cultivars
Phytoparasitica 29 (1), 29-35
Abstract: Pratylenchus thornei densities were monitored in field plots of two winter wheat 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 bread wheat cv. 'Yecora', densities of P. 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 of this cultivar but were unable to reproduce. These observations suggest resistance of wheat cv. Donpedro to P. thornei.
