Comparison of agronomic traits and photosynthetic characteristics between NILs of qPH8.2. (a–f) Morphology difference between NIL-9311 and NIL-NIP at the seedling stage with 10 days after germination (a), at the tillering stage with 50 days after germination (b), and at the heading stage (c–f). Scale bar: 10 cm. (g–r) Differences in plant height at the seedling (g), tillering (h), and heading stage (i), internode length (j), panicle length (k), flag leaf length (l), heading date (m), and tiller angle (n), panicle number (o), grain number per panicle (p), 1000-grain weight (q) and yield per plant (r). Data are given as mean ± SD (n = 20). ** denotes significant differences at p < 0.01 by t-test. (s–v) Differences in photosynthetic rate (s), stomatal conductance (t), intercellular CO₂ concentration (u), and transpiration rate (v). Data are given as Mean ± SD (n = 3). * and ** denote significant differences at p < 0.05 and p < 0.01 by t-test, respectively.
