Resumen

Swedish wheats were analysed at the seedling stage for hydroxamic acids (Hx), a family of natural aphid resistance factors. Analysis comprised the historical development from old landraces to modern cultivars, and included cultivars in the Swedish National List of Cultivars for 1992-93. Spring and winter wheats contained similar average Hx concentrations, 2.12±0.801 (n = 26) and 2.37 ± 0.816 (h = 49) mmol/kg fr. wt, respectively. Cultivars recommended for 1992-93 showed lower levels of Hx, 1.14 + 0.574 (n = 7) and 1.97 + 0.751 (n = 8), respectively. Breeding wheat for higher Hx levels as a means of obtaining increased aphid resistance is discussed.
