Identification of Bacterial Blight Resistance Loci in Rice ( L.) against Diverse Thai Strains by Genome-Wide Association Study.

Bacterial leaf blight (BLB) is a serious disease affecting global rice agriculture caused by pv. (). Most resistant rice lines are dependent on single genes that are vulnerable to caused by pathogen mutation.

Dissection of broad-spectrum resistance of the Thai rice variety Jao Hom Nin conferred by two resistance genes against rice blast.

Background: Rice (Oryza sativa) is one of the most important food crops in the world. Rice blast, caused by the fungal pathogen Magnaporthe oryzae, is one of the most destructive rice diseases worldwide. To effectively cope with this problem, the use of rice blast resistance varieties through innovative breeding programs is the best strategy to date.

Pseudo-backcrossing design for rapidly pyramiding multiple traits into a preferential rice variety.

Background: Pyramiding multiple genes into a desirable genetic background can take years to accomplish. In this paper, a pseudo-backcrossing scheme was designed to shorten the backcrossing cycle needed. PinK3, an aromatic and potentially high-yielding rice variety-although one that is intolerant to flash flooding (Sub) and susceptible to bacterial leaf blight (BB), leaf-neck blast (BL) and the brown planthopper (BPH)-was used as a genetic basis for significant improvements through gene pyramiding.
