TABLE 2.
Chi-square values on the probability of independent distribution of barley QTL for partial resistance to leaf rust (QTLpr), nonhost resistance to heterologous cereal and grass rusts (QTLnh), days to heading (QTLdh), plant height (QTLph) and yield (QTLyi), and defense gene homologs (DGH), over bins on a consensus genetic map of barley
| QTLpra | QTLnh | DGH | QTLdh | QTLph | QTLyi | |
|---|---|---|---|---|---|---|
| Marker no.b | 23c | 37 | 63 | 52 | 31 | 24 |
| Bin no.d | 22 | 27 | 43 | 39 | 28 | 23 |
| QTLpr | — | 12.12e | 9.42 | 0.28 | 7.27 | 0.18 |
| QTLnh | — | — | 10.93 | 1.11 | 0.13 | 0.40 |

Mapping data were obtained from this study (QTLpr and QTLnh), from Marcel et al. (2007) (QTLpr and DGH), and from the GrainGenes 2.0 databank (http://wheat.pw.usda.gov/) (QTLdh, QTLph, and QTLyi).
The number of (peak) markers mapped on the consensus map of barley (Marcel et al. 2007).
The chi-square values for which the null hypothesis of independent distribution is rejected with a probability P < 0.05 (with 1 d.f., P = 0.05 for χ2 = 3.841) are in italics.
The number of barley bins (5 cM) occupied by the (peak) markers for the respective class.
The chi-square values for which the null hypothesis of independent distribution is rejected with a probability P < 0.01 (with 1 d.f., P = 0.01 for χ2 = 6.634) are underlined.
