Association of mitogenome diversity with maize breeding lines. A Neighbor-joining (NJ) phylogenetic tree reconstructed using SNPs of the mitogenomes between breeding lines in different stages, 1960–1970s (yellow), 1980–1990s (light orange), and 2000–2010s (red). B Hierarchical clustering of principal components using 64 agronomic traits among breeding lines in different stages. Abbreviations are LAU (upper leaf angle), ASI (anthesis to silking interval), LW (leaf width), LAL (lower leaf angle), ULN (upper leaf number), TL (tassel length), TBN (tassel branch number), LL (leaf length), PH (plant height), EH (ear height), EP (relative ear position), DTS (days to silking), and DTA (days to anthesis). LAU and LAL are boxed to indicate their antagonistic relationship
