“…A large genotypic variation was observed here for all studied root traits (Tables 3 and 4). These results confirm the broad variability found for morphological traits in seminal [20,23,30] and adventitious roots [15,28,31,32]. All these studies were done in wheat, maize or sunflower.…”

In order to study seminal roots morphology in barley grown under different water treatments, experiments were carried out under glasshouse-controlled conditions. Eight genotypes were cultivated under four water treatments (100, 75, 50 and 25% of field capacity). Seminal root length and root-to-shoot dry matters' ratio were measured. Root volume was assessed at three soil depths. Results showed broad genotypic differences for all traits. The effect of low and moderate water deficit was slight. In contrast, the impact of severe water treatment was strongly marked on all traits. The impact of water deficit intensity on root traits at different soil depths is discussed.

“…Norin 61, Shiroganekomugi, and Chikugoizumi were chosen because they are major cultivars in the Kanto-Kyushu area , and Shiroganekomugi, Minaminokomugi, and Kinuhime were selected because they showed different root growth angles (Oyanagi et al, 1991(Oyanagi et al, , 1993(Oyanagi et al, , 2001). …”

“…Lodging susceptibility exhibited a positive association with root NW and number of root tips, that is, good lodging resistance was associated with deeper root network and fewer root tips. Root architecture's role in lodging tolerance varies across crops, with deeper root systems correlated with lodging tolerance in rice (Furuhata & Arima, 2007), whereas shallow root systems were correlated with lodging tolerance in wheat (Oyanagi et al., 2001). The findings of this study suggest that deeper root systems with better anchorage may be crucial for preventing lodging in peas.…”

Root system architecture (RSA) plays a central role in water and nutrient acquisition in plants. Plasticity and genetic variation in RSA can be used as an adaptive strategy to optimize plant performance under variable environments. We quantified phenotypic variation for seedling RSA among 44 diverse pea (Pisum sativum L.) genotypes, including breeding lines and germplasm accessions, grown under controlled conditions for 14 days using two‐dimensional hydroponic root imaging. Root image analysis revealed significant genotypic variability among the lines for all root traits, namely root length (RL), root diameter (RD), root volume, root surface area, number of tips, network width (NW), network depth (ND), and network convex area. Significant positive correlations were observed among the evaluated root traits, ranging from 0.5 to 0.9. Pea lines were ranked based on estimated means for root traits, with lines E20, F1, and F8 showing high rankings, while E4 and F5 received low rankings for most traits. To associate root traits with nitrogen (N) fixation and field agronomic performance, we performed redundancy analysis (RDA). The quantified root traits accounted for significant variation in the agronomic traits (R2 = ∼30%, p < 0.001). RDA showed a positive association between lodging susceptibility and root system NW and between plant height and root system ND. RD was positively associated with grain yield and N fixation. N fixation was positively associated with the number of lateral roots. The findings of this study indicate that variation for seedling root traits in pea could aid selection for N fixation and other important agronomic traits.
