Other claims from this paper (19)
- Intervention effect Drought stress at two locations of a winter triticale trial increased field heterogeneity.
- Intervention effect Drought stress at two locations of a winter triticale trial lowered heritabilities compared with the four non-stress locations.
- Intervention effect Heritability could be increased by modeling incomplete block and row effects, by using visual drought scorings as covariates, and by modeling spatial covariance between adjacent plots.
- Recommendation The most suitable model for analysing these field trials can be identified using the Akaike Information Criterion.
- Association Dynamic yield stability of genotypes depended strongly on the specific set of test environments.
- Association Heritability can be increased when the number of test environments is increased.
- Association At least 40 barley test environments should be used to obtain a heritability of 0.5 for yield stability.
- Observation The magnitude of heritability of yield stability varied strongly within and between barley series.
- Observation CMS-based barley hybrids had a midparent heterosis of around 10%.
- Observation CMS-based barley hybrids could compete with and partially surpass outstanding commercial inbred lines in registration trials.
- Observation No CMS-based triticale hybrid outyielded the best inbred line for grain yield.
- Mechanism The low yield performance of triticale hybrids is probably associated with the CMS system.
- Observation Wheat and barley hybrids had on average significantly higher dynamic yield stability than inbred lines.
- Observation Triticale hybrids did not show higher dynamic yield stability than inbred lines.
- Observation In the barley registration trials, hybrids had the highest dynamic yield stability on average.
- Observation CMS-based triticale hybrids had on average significantly lower dynamic yield stability than their female parents and commercial inbred lines across 20 environments.
- Observation Hybrids of wheat and barley possessed an increased yield potential.
- Observation CMS-based triticale hybrids showed only marginal yield advantages.
- Observation CMS-based triticale hybrids had low dynamic yield stability.
