Heterotic effects on final leaf length in controlled conditions in a growth chamber (GC) and in field conditions (2014–2015)

	2014		2015		GC
	(%MPH)	(%BPH)	(%MPH)	(%BPH)	(%MPH)	(%BPH)
B104xCML91	27.6**	15.7**	41.0**	38.9**	8.6*	−0.7
B104xF7	52.2**	47.3**	47.7**	38.2**	13.8**	5.1
B104xH99	22.1**	16.4**	25.8**	12.3**	1.7	1.6
B104xMo17	12.7**	−1.1	17.3**	10.2**	9.1**	5.3
B104xW153R	8.4**	7.8**	20.1**	19.4**	8.3*	5.0

Note. The %MPH and %BPH values refer to the average hybrid performance relative to the mid‐parent or best‐parent value, respectively.

MPH = mid‐parent heterosis; BPH = best‐parent heterosis.
