      Soybeans (Glycine max L.).

AB  - Roots are the most important plant organ for absorbing essential elements, such 
      as water and nutrients for living. To develop new climate-resilient soybean 
      cultivars, it is essential to know the variation in root morphological traits 
      (RMT) among diverse soybean for selecting superior root attribute genotypes. 
      However, information on root morphological characteristics is poorly understood 
      due to difficulty in root data collection and visualization. Thus, to overcome 
      this problem in root research, we used a 2-dimensional (2D) root image in 
      identifying RMT among diverse soybeans in this research. We assessed RMT in the 
      vegetative growth stage (V2) of 372 soybean cultivars propagated in polyvinyl 
      chloride pipes. The phenotypic investigation revealed significant variability 
      among the 372 soybean cultivars for RMT. In particular, RMT such as the average 
      diameter (AD), surface area (SA), link average length (LAL), and link average 
      diameter (LAD) showed significant variability. On the contrary RMT, as with total 
      length (TL) and link average branching angle (LABA), did not show differences. 
      Furthermore, in the distribution analysis, normal distribution was observed for 
      all RMT; at the same time, difference was observed in the distribution curve 
      depending on individual RMT. Thus, based on overall RMT analysis values, the top 
      5% and bottom 5% ranked genotypes were selected. Furthermore, genotypes that 
      showed most consistent for overall RMT have ranked accordingly. This ultimately 
      helps to identify four genotypes (IT 16538, IT 199127, IT 165432, IT 165282) 
      ranked in the highest 5%, whereas nine genotypes (IT 23305, IT 208266, IT 165208, 
      IT 156289, IT 165405, IT 165019, IT 165839, IT 203565, IT 181034) ranked in the 
      lowest 5% for RMT. Moreover, principal component analysis clustered cultivar 2, 
      cultivar 160, and cultivar 274 into one group with high RMT values, and cultivar 
      335, cultivar 40, and cultivar 249 with low RMT values. The RMT correlation 
      results revealed significantly positive TL and AD correlations with SA (r = 0.96) 
      and LAD (r = 0.85), respectively. However, negative correlations (r = -0.43) were 
      observed between TL and AD. Similarly, AD showed a negative correlation (r = 
      -0.22) with SA. Thus, this result suggests that TL is a more vital factor than AD 
      for determining SA compositions.
