Title

Theoretical and experimental investigations on the exploitation of heterosis in hybrid breeding

Sandra E. Fischer University writing server of the University of Hohenheim (Universität Hohenheim) 2009

Other claims from this paper (18)

Observation Triticale had low heterosis.
Association Between-group factorials had a higher GCA-to-SCA variance ratio than within-group designs.
Association Genetically distinct populations showed a more favorable GCA-to-SCA ratio than less distinct populations.
Method / resource The enumeration algorithm improved all criteria for identifying heterotic groups.
Observation F1 performance was the leading criterion for developing and enriching heterotic groups.
Observation Heterosis was the next most important criterion for developing and enriching heterotic groups.
Observation US exotic maize germplasm had higher genetic diversity than Central European groups.
Recommendation The authors recommend introgressing non-Stiff Stalk germplasm into the Flint group.
Recommendation The authors recommend introgressing Stiff Stalk germplasm into the Dent group.
Observation East European rye OPVs had higher genetic diversity than Central European groups.
Observation The Carsten rye group had a narrow genetic base.
Recommendation The authors recommend the Carsten group as the primary target for genetic broadening.
Association All five rye OPVs were genetically closer to Petkus than Carsten.
Observation Two rye OPVs were good candidates for introgression into Petkus.
Observation One rye OPV was a good candidate for introgression into Carsten.
Recommendation The authors suggest using selected clones of these rye populations for introgression.
Observation Maize GCA variance remained predominant over SCA variance.
Recommendation The authors recommend continually enriching heterotic groups through germplasm introgression.
