Table 4. Chi-square values on the probability of independent distribution of QTLs for all types of resistance (QTLres) with DGH-based markers (with and without Prx), and three sets of microsatellites: GBM, scssr and Bmac+Bmag markers.

	QTLres1	DGH (Prx)	DGH	GBM	scssr	Bmac+Bmag
Marker no. 2	105	97	65	244	34	97
BIN no. 3	70	63	48	133	28	66
O (E) 4		27 (20.3)	18(15.5)	48 (42.9)	7 (9)	21 (21.3)
χ2 5		4.6*	0.8	2.3	1.0	0.02

¹Mapping data were obtained from previous works [13], [14], [22], [32], [33], [34], [35].

²The number of markers or QTL peak markers mapped on the integrated map of barley.

³The number of barley BINs (5 cM) occupied by the (peak) markers for the respective class of QTLs or markers.

⁴Number of BINs observed to be co-occupied by a QTL peak marker and a Prx-targeted marker/other marker (the expected number of co-occupied BINs is in brackets).

⁵Chi-square values in bold indicate the rejection of independent distribution with a probability P<0.001 (with 1 d.f., P = 0.001 for χ² = 10.83) or P<0.05 (with 1 d.f., P = 0.05 for χ² = 3.84).
