t0“Durum Wheat”
e1“the repeatability as measured by both coefficients was high for heading time ( r ≥ 0.73), moderately high for kernel weight and plant height (0.48 ≤ r ≤ 0.57), relatively low for grain yield and kernels per spike (0.18 ≤ r ≤ 0.30), and non‐significant for early vigor score”
e0“A subset of 600 entries from a world collection was evaluated for six agronomic traits at one site in northern Syria and one in Sicily”

Other claims from this paper (8)
- Association Repeatability of entry values between the two locations was high for heading time (r ≥ 0.73).
- Association Repeatability of entry values between the two locations was relatively low for grain yield and kernels per spike (0.18 ≤ r ≤ 0.30).
- Association Repeatability of entry values between the two locations for early vigor score was not significant.
- Mechanism Comparison of phenotypic and genetic correlations suggests that genotype × location interaction and experimental error both contribute substantially to departures from complete repeatability.
- Method / resource When each location served as selection site and the other as test site, at least 50% of the selection advantage of the top 10% entries was maintained at the test location for early or late heading, high kernel weight, and short or tall stature.
- Observation For early or late heading, high kernel weight, and short or tall stature, 30 to 57% of selected entries were common to both sites.
- Method / resource At least 20% of the selection advantage was maintained at the test location for high kernels per spike and grain yield.
- Recommendation The results support the potential usefulness of large-scale germplasm evaluation trials for crop improvement.
