Characterization of the Newly Developed Soybean Cultivar DT2008 in Relation to the Model Variety W82 Reveals a New Genetic Resource for Comparative and Functional Genomics for Improved Drought Tolerance

Figure 4

Comparison of root growth and development of DT2008 and W82 plants under well-watered conditions. (a) Comparison of primary root lengths of 5- and 10-day-old DT2008 and W82 plants. (b) Comparison of numbers of secondary root of 5-day-old DT2008 and W82 plants. (c) Comparison of dry weights of root biomasses of 5-, 10-, 20-, and 25-day-old DT2008 and W82 plants. Error bars represent standard errors. For 5- and 10-d-old plants, 𝑛=20 plants/genotype. For 20- and 25-d-old plants, 𝑛=10 plants/genotype. Asterisks indicate significant differences as determined by a Student’s 𝑡-test (*𝑃<0.05; ***𝑃<0.001).
