Root Biomass Distribution with Root and Shoot Development at Different Growth Stages of Wild, Ancient and Modern Wheat Species

This study was conducted to investigate root and shoot traits of wild, ancient and modern wheat genotypes belonging to 8 different species at long tubes under field weather conditions. It was found significant differences between genotypes with regard to root and shoot traits. The research results indicated that root biomass distribution of genotypes at GS 31 ad GS 69, respectively was found 59.2% and 56.3% in 0-30 cm, 76.7% and 71.9% in 0-60 cm. Modern wheats (Çeşit 1252, Konya 2002) and Triticum vavilovii (ancient wheat) had high root biomass distribution in top soil. In the study, species with AABBDD genomes had higher root length than those with AABB, AABBGG and AA genomes. Triticum dicoccoides, Triticum timopheevii and Triticum monococcum had lower values than other genotypes in terms of root length, crown root number, root biomass, shoot biomass and plant height at both growth stages (GS 31 and GS 69), while Triticum vavilovii and Triticum spelta (hexaploid) took part in the front. Accordingly, Triticum vavilovii and Triticum spelta may be used in breeding programs to improve new modern cultivars with high root and shoot traits.
