“…Twelve genotypes from six different grain legume species were evaluated in a plexiglass early vegetative root analysis system (Hohn and Bektas, 2020). The system allowed us to observe complete roots system architecture and diversity of lateral root initiation within and between legume species (Tables 3-7).…”

Grain legumes known as “Pulse crops” are economically and nutritionally one of the most important crop families after cereals. Climate change and abiotic stress factors are limiting yield potential in these crops. Root system architecture, a neglected field, is promising for improved environmental adaptability and higher growth potential. Genotypes with deep and dense root system may cope better with water and nutrient limitations. This study aimed to evaluate 12 common cultivars from six different legume species. Root system architectures were evaluated under controlled conditions in a plexiglass system at the early vegetative stage. Roots were divided into four depth zones (0, 5, 10, 15> cm), and inter and intra species diversity were analysed. Significant diversity was obtained within and between the species. Bean, chickpea, and broad bean constituted deeper and dense root systems while lentil, soybean, and pea formed non-dense and shallower root systems. There was a significant correlation between earliness and early vegetative root vigour. The results of the study may provide a better understanding of the root system architectures of each species-genera. The results presented here may shed light on the selection of root traits in legume breeding programs.

“…The next day, seeds were placed on a germination paper (40*40 cm) covered with two layers of plexiglass plates and laid in a container with appr. 45° angle as described in Hohn and Bektas (2020). The plastic container was filled with distilled water up to 70% capacity to provide adequate moisture to seeds.…”

“…It consisted of two plexiglass plates 20 cm x 30 cm fitted with spacers, germination paper, racks holding the plates upright, and tubs used to hold water. Details of the experimental design were given in Hohn and Bektas (2020). Briefly, seeds of similar size from each line were sterilized with 1% sodium hypochlorite (NaClO) solution and rinsed with distilled water.…”

Root system architecture, as a complex trait, has gained attention due to climate change and abiotic stress pressure on crops. The incorporation of root traits in breeding objectives may enable new advances in climate-resilient crops. Here, the genetics of the seedling root system architecture in the Synthetic W7984 × Opata M85 Doubled Haploid mapping population was investigated. Three traits at the seedling stage and mature stage root and shoot biomass traits were mapped for Quantitative Trait Loci (QTL) identification. A total of five different loci on chromosomes 1B, 5A, and 7D with major effects were identified for total root length, primary root length, and seminal root growth angle. Four regions on chromosomes 2A, 5A, and 7D had colocating loci for seedling and mature stage root traits. Chromosome 5A, with a locus affecting most of the seedling root traits, is promising. The correlations between seedling and mature root traits, and newly identified QTL for seedling root traits, may be promising to unravel the genetic structure of root traits and for the marker-assisted selection.
