  1. Abbr. = abbreviation of trait; Norm. = transformation used to achieve normality. Eight locations representing three agro-ecologies in Ethiopia; Akaki (AK), Alemtena (AL), Debre Zeit Black Soil (DZBS), Debre Zeit Light Soil (DZLS), Denbi (DE), Melkasa (MEL), Chefe (CH) and Holetta (HO), wet semi-arid in higher than 1900 masl altitude (C2-1; AK, CH, HO), wet semi-arid in 1700–1900 masl altitude (C2-2; DZBS, DZLS, DE), dry semi-arid in lower than 1700 masl altitude (C3-3; AL, MEL). Each experiment representing the combination of different environments and years for each trait evaluation; AK and 2000 (e01), AL and 2000 (e02), DZBS and 2000 (e03), DZLS and 2000 (e04), DE and 2000 (e05), MEL and 2000 (e06), CH and 2000 (e07), HO and 2000 (e08), AK and 1999 (e09), AL and 1999 (e10) and DZBS and 1999 (e11).
  2. a culm diameter of 1st internode
  3. b culm diameter of 2nd internode
  4. c measurement of penetration strength in 1st internode rind
  5. d measurement of penetration strength in 2nd internode rind
  6. e measurement of crushing strength in 1st internode
  7. f measurement of crushing strength in 2nd internode
  8. *** The analysis of variance for traits among lines and experiments at significance of 0.001 probability level
