Arkansas, United States	GSOR	2012	DEVELOPED	2009	Genetic material	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) were inoculated with the race IB49 of Magnaporthe oryzae that recognizes Pi-ta. The resistant progeny were identified during backcrossing for five generations. This set of materials (42 BC5F3) can be used to study biological effects of large chromosomal introgressions of chromosome 12 from indica origin into a temperate japonica. This set of materials can also be used to develop medium grain blast resistant rice cultivars.	1904147	GSOR 102501

The resistant progeny were identified during backcrossing for five generations. This set of materials (42 BC5F3) can be used to study biological effects of large chromosomal introgressions of chromosome 12 from indica origin into a temperate japonica. This set of materials can also be used to develop medium grain blast resistant rice cultivars.	1904185	GSOR 102539
