Phenotypic variation and heritability for root and shoot traits of the spring barley collection.
| Trait | Genotype no. | Min | Max | Mean ± SD | CV(%) | h2(%) |
|---|---|---|---|---|---|---|
| RSD | 221 | 8.15 | 34.03 | 25.57 ± 4.5 | 17.60 | 84.7 |
| RSA | 221 | 46.67 | 131.67 | 70.5 ± 17.99 | 25.52 | 84.9 |
| SRN | 221 | 4.22 | 8.00 | 5.87 ± 0.9 | 15.33 | 72.7 |
| TSRL | 219 | 64.56 | 170.43 | 125.17 ± 32.44 | 25.92 | 54.4 |
| ASRL | 219 | 14.59 | 29.95 | 21.53 ± 5.45 | 25.56 | 42.9 |
| SDW | 221 | 18.05 | 70.13 | 45.9 ± 11.84 | 25.80 | 73.8 |
Given are the total number of genotypes scored for each trait with its minimum and maximum values, the mean ± SD and the heritability (h2). RSD, root system depth; RSA, root spreading angle; SRN, seminal root number; TSRL, total seminal root length; ASRL, average seminal root length; SDW, shoot dry weight.
