Genetical analysis of the efficiency of VA mycorrhiza with spring wheat

I. Genotypical differences and a reciprocal cross between an efficient and non-efficient variety
  • G. G. B. Manske


To quantify the variability of the mycorrhizal efficiency in wheat, wild forms, Landraces (LRs), and High Yielding Varieties (HYVs) were investigated with respect to dry weight of the ears and shoots, plant height, total root length, P concentration, P uptake, infection rate of the VAM fungus Glomus manihotis in wheat roots and total infected root length

Under P deficiency the VA mycorrhiza showed a higher efficiency in growth response with most of the LRs than with HYVs. The efficient wild variety Triticum aestivum rotundatum and the African HYV ‘Huanca’ were crossed reciprocally. Chromosomal heredity could be observed. In some genotype x environment interactions differences between the reciprocal F1 indicated also plasmatic effects.
