Figure 2

Trait values of landraces vs. breeding varieties. Bar graphs of mean (SD) phenotypic values: (a) ODMI in 2018; (b) BM in 2018; (c) culm length in 2018; (d) ODMI in 2019; (e) BM in 2019; (f) culm length in 2019. The yellow and blue bars indicate landraces and breeding varieties, respectively. *** indicates significant differences at P < 0.001 (two-tailed Welch’s t-test). Two-tailed Welch’s t-test was performed by R software (https://www.R-project.org/)⁶⁵.
