- Association The three teosinte parents were superior to the four maize parents in most growth characters and forage productivity.
- Association Teosinte parent Gemmeiza 3 (T1) produced the highest values of most characters and forage productivity.
- Association Maize parent S.C. 130 (L1) produced the highest values of most characters and forage productivity.
- Association All 12 tested maize-teosinte crosses had the highest values of most measured traits, higher than their parents.
- Association Cross S.C. 130 x Gemmeiza 3 (L1 x T1) gave the highest values under the three irrigation regimes.
- Observation Analysis of variance was highly significant among the tested genotypes for most characters under the three irrigation regimes.
- Observation Maize genotype S.C. 130 (L1) showed highly significant general combining ability effects for most characters.
- Observation Teosinte genotype Gemmeiza 3 (T1) showed highly significant general combining ability effects for most characters.
- Association Cross L1 x T1 showed the highest significant positive specific combining ability effect for all traits and forage yields.
- Association Cross L4 x T3 showed the highest significant positive specific combining ability effect for all traits and forage yields.
- Association GCA/SCA variance ratios for all traits were less than unity.
