Identification of genomic regions involved in tolerance to drought stress and drought stress induced leaf senescence in juvenile barley.

ABSTRACT:

Background

Premature leaf senescence induced by external stress conditions, e.g. drought stress, is a main factor for yield losses in barley. Research in drought stress tolerance has become more important as due to climate change the number of drought periods will increase and tolerance to drought stress has become a goal of high interest in barley breeding. Therefore, the aim is to identify quantitative trait loci (QTL) involved in drought stress induced leaf senescence and drought stress tolerance in early developmental stages of barley (Hordeum vulgare L.) by applying genome wide association studies (GWAS) on a set of 156 winter barley genotypes.

Results

After a four weeks stress period (BBCH 33) leaf colour as an indicator of leaf senescence, electron transport rate at p
