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

Botanical Studies

Table 2 Significant QTLs identified from 166 recombinant inbred lines (RILs) of ‘TK16’ × ‘Budda’

QTL	Chromosome	LOD score	QTL region (cM)	QTL region (bp)^a	Interval size (bp)	Bin marker nearest the QTL peak ^b	Variation explained (%)	Additive effect (%)^b	Number of genes in the QTL
qBK2.1	2	6.13	60.51–83.59	21,978,086 − 30,150,853	8,172,767	chr2_22618014_22621772	8.1	3.7	1,060
qBK1.8	1	4.75	23.82–33.98	5,244,677-8,664,285	3,419,608	chr1_6471731_6602276	4.9	2.9	442

^a The genomic position is based on the IRGSP-1.0 reference genome
^b The peaks of qBK2.1 and qBK1.8 were identified at 62.3 and 29.7 cM, respectively. The bin markers nearest the QTL peaks were located at 22,618,014–22,621,772 bp on chromosome 2 and 6,471,731-6,602,276 bp on chromosome 1
^c Positive value indicates the resistant effect of the ‘Budda’ allele
