Factors affecting heterotic grouping with cross‐pollinating crops

Agronomy Journal, 2020
AbstractHeterotic grouping based on the analyses of heterosis or combining ability and molecular diversity has not been consistent. The objectives of this study were to investigate the factors affecting heterotic grouping and the significance of the phenotypic and molecular data.

Creation of Heterotic Groups and Hybrid Varieties

2010
Capturing heterosis for dry matter yield in forage crops needs to consider both the final product of the breeding process (the type of cultivar) and the breeding method used to produce the cultivar. The discussion is focused specifically on alfalfa and on the semi-hybrid variety model allowing partial expression of heterosis with the technology ...

Comparing the efficiency of the three heterotic-group and traditional two heterotic-group classifications for the hybrid maize breeding

2020
Increasing the efficiency of the hybrid-based maize breeding program has highly contributed to the heterotic group classification. The present study was aimed to compare the breeding efficiency of the three heterotic-group (TriHG) classification [Lancaster Sure Crop (LSC), Reid Yellow Dent (RYD), CIMMYT] system and usual two heterotic-group (DiHG ...

Heterotic Grouping and the Heterotic Pattern among Chinese Rapeseed (Brassica napus L.) Accessions

Agronomy Journal, 2015
Heterotic groups and patterns are extremely important in hybrid breeding. Nine elite inbreds widely used in Chinese rapeseed hybrid breeding programs were crossed in a diallel mating design to develop 36 hybrids. These hybrids and their parents were evaluated for two successive years in northern China.

The crystallographic space groups and Heterotic string theory

Chaos, Solitons & Fractals, 2009
Abstract While the 17 planar crystallographic groups were shown to correspond to 17 two and three Stein spaces with a total dimension equal to Dim E 12 = 5 α ¯ o ≅ 685 , the present work reveals that the corresponding 219 three dimensional groups leads to a total dimensionality equal to N o ≅ 8872

Improvement Of The M017 Family Of The Lancaster Heterotic Group of Maize

Cereal Research Communications, 2004
All maize inbreds have been classified into heterotic groups based on pedigree information or combining ability. The Lancaster Sure Crop and BSSS heterotic groups are the most commonly used heterotic pair to developing commercial maize hybrids in central and southern Europe.

Potential Heterotic Groups in Hop as Determined by AFLP Analysis

Crop Science, 2005
Hop (Humulus lupulus L.) is a perennial, dioecious species in which the female inflorescence (cones) are harvested and used in the beer‐brewing process to impart bittering and/or flavoring to beer. Hop breeders have typically utilized clonal selection and hybridization to develop new cultivars.

NO SIEGEL ANOMALY FOR D=4 HETEROTIC σ-MODELS ON GROUP MANIFOLDS

Modern Physics Letters A, 1991
We prove that the conditions for cancellation of the anomaly in Siegel symmetry for the D=4 heterotic σ-models on group manifold and the (1, 0) non-Abelian lefton-righton Thirring models are the same as in the free string case.

Pedigree Diversity within the Lancaster Surecrop Heterotic Group of Maize

Crop Science, 1993
Maize (Zea mays L.) breeders commonly classify inbred lines into heterotic groups based on pedigree information and/or combining ability. These heterotic groups influence how germplasm is used, and have increased the efficiency of breeding programs. The most widely recognized and exploited heterotic pattern in the U.S.
