Triticale (x Triticosecale Wittmack), a cross between wheat and rye, has the potential to become a valid
alternative to other small cereals and could thus diversify crop rotations and increase biodiversity in
agricultural production. As a multi-purpose grain-forage species it has the reputation of performing well
on marginal soils, even with reduced nutrient input. Although triticale was considered as a healthy crop
compared to e.g., wheat, in recent years disease susceptibility is one of the main issues limiting its
introduction into cropping systems. The most urgent targets of triticale breeding are therefore durable
resistance against diseases of which yellow (stripe) rust caused by Puccinia striiforimis f. sp. tritici (Pst) is
one of the biggest problems given the presence of some very aggressive isolates (e.g,, ‘Worrior race’).
In this study, 280 triticale accessions were grown in an augmented design, during two growing seasons
in four different agro-ecological zones. The...se accessions were evaluated for their resistance to yellow
rust, but also other phenotypic characteristics such as soil cover, plant height, flowering time and grain
yield were noted. The variation in genetics was mapped using DAFT (Diversity Arrays Technology)
markers.
The phenotypic screening of the triticale revealed that there is a considerable variation in yellow rust
incidence between years, locations and triticale genotypes. In addition, the tolerant genotypes originated
from different breeders, which can be an indication of the presence of different sources of resistance
within this population. Also, on the genetic level, there was a great variation between the genotypes,
which is essential to continuously improve triticale by breeding efforts. In the next phase, a GWAS study
willlink the genetic data to the phenotypic data to find informative markers for future breeding. The data
collection and analyses are currently running. Results will be analyzed, and conclusions drawn.
