Fine mapping of qBK1, a major QTL for bakanae disease resistance in rice

Utilization of marker-assisted selection (MAS) with a precise molecular marker on qBK1 could provide an effective tool for breeding rice varieties resistant to bakanae disease.

Molecular mapping of qBK1Z, a major QTL for bakanae disease resistance in rice

Introducing qBK1z or pyramiding with other previously identified QTLs could provide effective genetic control of bakanae disease in rice.

Mapping of a Major QTL, qBK1Z, for Bakanae Disease Resistance in Rice

Introducing qBK1z or pyramiding with other previously identified QTLs could provide effective genetic control of bakanae disease in rice.

A Novel Locus for Bakanae Disease Resistance, qBK4T, Identified in Rice

This study proposes qBK4T as a novel locus for Bakanae disease resistance, which was mapped on chromosome 4 and flanked by AX-116847364 and AX-115752415 and could be useful for marker-assisted breeding and functional characterization of resistance genes against bakanae Disease.

Genome-wide association mapping of gene loci affecting disease resistance in the rice-Fusarium fujikuroi pathosystem

A genome-wide association study was conducted to identify genes/loci conferring bakanae resistance in rice and revealed that the coding regions of two LRR-containing genes Os01g0601625 and Os01 g0601675 may be associated with bakanase resistance.

Fine mapping of qBK1.2, a major QTL governing resistance to bakanae disease in rice

MassARRAY-based single-nucleotide polymorphism (SNP) assays targeting the genomic region of qBK1.2.2 helped in fine mapping the QTL to a region of 130 kb between the SNP markers rs3164311 and rs3295562 using 24 recombinants and identified 11 putative candidate genes with functions related to defense.

Identification of qBK2.1, a novel QTL controlling rice resistance against Fusarium fujikuroi

The discovery of qBK2.1 has provided a new source of bakanae resistance and the resistant RILs inheriting good plant type, good taste, and high yield characteristics from ‘TK16’ can be used as good resistance donors.

Rice Genome Resequencing Reveals a Major Quantitative Trait Locus for Resistance to Bakanae Disease Caused by Fusarium fujikuroi

It is found that eight genes exhibited non-synonymous single nucleotide polymorphisms (SNPs) by comparing the ‘Junam’ and ‘Samgwang’ genome sequence data, and are possibly candidate genes for qFfR9, a major QTL discovered at 30.1 centimorgan on chromosome 9 with a logarithm of the odds score of 60.3.

Map-Based Cloning and Characterization of a Major QTL Gene, FfR1, Which Confers Resistance to Rice Bakanae Disease

Bakanae disease (BD), caused by the fungal pathogen Fusarium fujikuroi, is a serious threat to rice production worldwide. Breeding elite rice varieties resistant to BD requires the identification of…

Screening of Rice Germplasm for Bakanae Disease Resistance in Rice

Bioassay showed that 11 varieties including Gwangmyeongbyeo, Hawn, Wonseadaesoo, Erguailai etc. were resistant to bakanae disease among 254 rice germplasm, suggesting that RM9 might be used for selecting qBK1, but it cannot beused for wide range of rice germ plasm.
