Genetic variability for Russian wheat aphid, Diuraphis noxia resistance in South African wheat genotypes
Near-isogenic genotypes 1684/Tugela and 2199/Tugela containing D. noxia resistance ex SA1684 [PI 137739 (Dn1)] and SA 2199 [PI 262660 (Dn2)] were studied in terms of antibiosis, antixenosis and tolerance, population development of D. noxia under field conditions and the probing behaviour of D. noxia...
