| dc.description.abstract | Sclerotinia sclerotiorum causes white mold and severe yield losses of pea. 484 accessions from the Pisum core collection were screened for resistance using a mini-agar plug technique. 49, 41, and 13 accessions were identified with partial resistance based on lesion expansion inhibition (LEI), nodal transmission inhibition (NTI), and both traits combined, respectively. A genetic linkage map based on F2 DNA from the cross, Lifter/PI240515, was developed with 78 markers on 9 linkage groups (LG) spanning 734 cM. Two quantitative trait loci (QTL) were identified based on phenotypic data from F2:3 and F3:4 families. A single QTL on LGIII explained 34.1% of the phenotypic variation for LEI, while a second QTL on LGII(b) explained 2.5% of the phenotypic variation for NTI. This is the first report of QTL for S. sclerotiorum resistance in pea which will be useful in development of resistant pea varieties. | en_US |
