Genetic group	Number of accessions	Protein (%)^c	Fat (%)^c	Starch (%)^c	Predominant race	Predominant country
A	46	12.6 ± 2.3^a	3.0 ± 0.6^a	66.1 ± 1.6^a	durra, bicolor-durra	Ethiopia, India
B^b	2	13.1 ± 3.4	3.5 ± 1.4	65.9 ± 1.0	bicolor-guinea	Ethiopia
C	55	10.9 ± 2.0^b	2.7 ± 0.6^a,b	67.6 ± 1.2^b	kafir	USA, India, S. Africa
D	23	11.6 ± 1.8^a	3.0 ± 0.5^a	67.2 ± 1.3^b	caudatum, guinea	Nigeria, USA
E	117	11.2 ± 1.8^b	2.6 ± 0.6^b	67.1 ± 1.2^b	caudatum	Sudan, USA, Ethiopia, Uganda

^aData represent mean grain composition concentrations across 3 years
^bGenetic grouping B was not considered in analysis due to the small sample size
^cValues in the same column with different letters are significantly different from each other, based on a post hoc Tukey HSD test
