Table 2.

Analysis of variance and mean values for yield components and phenology traits for landraces from east and west of the Mediterranean Basin.

Environment	Yield	NSm2	NGm2	TKW	DSB	DBA	GFD
East Mediterranean	312	441	7155	44	139	16	33
West Mediterranean	311	388	6236	50	143	17	31
Numerator D.F.	1	1	1	1	1	1	1
Denominator D.F.	53	53	53	53	53	53	53
F value	0.01	26.27	15.17	24.42	74.56	46.68	21.14
P-value	0.9377	<0.0001	0.0003	<0.0001	<0.0001	0.0002	<0.0001

Data on first two rows are means across six environments. Yield, grain yield (g m⁻²); NSm², number of spikes per m²; NGm², number of grains per m²; TKW, thousand grain weight; DSB, days from sowing to booting; DBA, days from booting to anthesis; GFD, grain filling duration (days); DF, degrees of freedom.
