Other claims from this paper (16)
- Observation Parental genotypes and their crosses significantly affected all investigated agro-morphological traits in bread wheat.
- Observation ISSR and SCoT-PCR markers revealed 28 polymorphic loci out of 76 amplified in the wheat genotypes.
- Observation Parental genotypes P1 and P3 had positive and significant GCA effects for shoot fresh weight, shoot dry weight and root fresh weight under well-watered conditions.
- Observation Parental genotypes P1 and P3 had positive and significant GCA effects for root dry weight, shoot length and root length under well-watered conditions.
- Observation P3 and P5 recorded the highest GCA estimates under drought stress.
- Observation P3 and P4 had the highest GCA effects for spikelet number, grain number and grain weight per spike under normal conditions.
- Observation P5 had the maximum GCA effects and was the best combiner under drought stress conditions.
- Observation The cross P1× P3 had the highest positive SCA effects for shoot fresh weight under normal conditions.
- Observation The cross P2×P3 excelled in specific combining ability under water deficit conditions.
- Observation The crosses P1× P2, P1× P3 and P4× P5 were most effective for shoot dry weight under normal conditions.
- Observation The crosses P1× P3 and P3× P5 showed significant SCA effects for shoot dry weight under drought stress.
- Observation The cross P3×P5 had positive SCA effects for root fresh weight and shoot length under stressed conditions.
- Observation The cross P4×P5 had the highest SCA for root length in both environments.
- Observation The evaluated genotypes were grouped by agronomic performance under drought stress, from drought-tolerant (group A) to drought-sensitive (group C).
- Recommendation The genotypes P5, P2×P5 and P3×P5 were identified as promising to improve agronomic performance under water deficit conditions.
- Observation The evaluated wheat genotypes show genetic variation for drought tolerance.
