Artificial introgression of a large chromosome fragment around the rice blast resistance gene Pi-ta in backcross progeny and several elite rice cultivars.

Abstract excerpt

Studying the size of genomic introgressions should lead to a better understanding of linkage disequilibrium in crop breeding. In this study, progeny of the cross between a tropical japonica rice cultivar Katy containing the rice blast resistance gene Pi-ta and a temperate japonica cultivar M202 (pi-ta)' [corrected]. were inoculated with the race IB49 of Magnaporthe oryzae that recognizes Pi-ta. The resistant...
