GrainGenes Trait Study Report: Leaf rust, Nelson97

[Submit comment/correction]

Trait Study	Leaf rust, Nelson97
Trait	Pathogenic disease reaction
Pathology	Leaf Rust
Reference	Nelson JC et al. (1997) Mapping genes conferring and suppressing leaf rust resistance in wheat. Crop Science 37:1928-1935.
Description	Leaf rust resistance was mapped in the Synthetic x Opata RI population, using natural infection and seedling and adult inoculation tests, at three locations.
Protocol	Seedling inoculation tests were performed in the greenhouse at El Batan, adult inoculations in the field at Ciudad Obregon, and natural infection was used at Ithaca.
Environment	Ciudad Obregon 1992-3 Lr [ Show all 6 ]
Map Data	Wheat, Synthetic x Opata
Population Size	114
Population Type	F7 single-seed-descent lines
QTL Analysis Method	Seedling IT tests: Chi-square of pooled resistance classes Adult field tests: Interval regression analysis About 400 markers were used for mapping, with an average spacing of 10 cM.
Markers Tested	400
Image	Lr genes on 2A, 2B and 2D Lr genes on 3B, 4B and 6D Lr genes on 7B and 7D Lr10 on 1A
Trait Score	Leaf rust at El Batan, BBB/BN [ Show all 13 ]
Data Source	Nelson, James C. 97.05
