re-tillering behavior of selected barley genotypes (cultivars and wild
barley introgression lines) in different drought and re-watering
scenarios, which were applied in a high-throughput phenotyping facility.
Re-tillering describes the activation of additional tillers after
post-stress irrigation. Results Twenty-three selected genotypes of the
barley NAM population HEB-25, along with three control genotypes, were
evaluated in four replicates under five distinct treatment conditions.
In this experiment, re-tillering was particularly pronounced in an
alternating watering and stress treatment, where the resumption of
irrigation post-stress enabled full recovery of the plants. However, it
was noted that while re-watering after a stress period promotes tiller
activation and the development of fertile ears, it also tends to
increase the number of sterile ears. The degree of sterile ear formation
varied significantly among different genotypes, highlighting the
critical role of genetic factors in modulating plant responses to
re-tillering and post-stress irrigation. It is important to note that
excessive re-tillering has been shown to exhibit a negative correlation
with fertile ear weight. Conclusions The impact of focusing on tiller
number and re-tillering behavior in future barley breeding may be
significant, particularly in the context of climate change. By selecting
for genotypes with appropriate tillering plasticity, breeders can
develop barley varieties that are more resilient to stress conditions
such as drought.},

down the analysis by the main genotype-by-environment trends revealed
QTLs and candidate genes specific to conditions like sowing date and

that early selection focused on PH and TGW, likely due to their high
heritability. GY selection occurred later, facilitated by reduced
variance in other traits. The study observed that favourable alleles for
plant height were often fixed before those for grain yield and TGW. Some
regions showed linkage in repulsion, suggesting targets for future
