Table 3.

Genotypic association among grain yield (GY) and domestication-related traits: thousand kernel weight (TKW), kernel number per spike (KNPS) and spike harvest index (SPHI).

Values indicate the number of corresponding QTLs with >50% overlap between their confidence intervals, out of the total number of QTLs detected for each trait (indicated in parentheses).

	TKW (12)	KNSP (9)	SPHI (6)
GY (6)	3*	1	4**
TKW (12)		3 (P=0.06)	4**
KNSP (9)			1

* and ** indicate significance at P ≤0.05 and 0.01, respectively.
