Use of SSRs for establishing heterotic groups in subtropical maize [PDF]
Theoretical and Applied Genetics, 2003 Heterotic groups and patterns are of fundamental importance in hybrid breeding. The objectives of our research were to: (1) investigate the relationship of simple sequence repeats (SSR) based genetic distances between populations and panmictic midparent heterosis (PMPH) in a broad range of CIMMYT maize germplasm, (2) evaluate the usefulness of SSR ...

Development of Heterotic Groups in Triticale
Crop Science, 2010Heterotic groups are an essential prerequisite for efficient hybrid breeding. The present study in winter triticale (×Triticosecale Wittmack) was performed to (i) evaluate the magnitude of heterosis, (ii) investigate the efficiency of the prediction of hybrid performance based on midparent value or general combining ability (GCA) effects, and (iii ...

Heterotic groups of tropical indica rice germplasm
Theoretical and Applied Genetics, 2014Four heterotic groups were identified for tropical indica rice germplasm to develop hybrid rice in the tropics based on two studies. Heterotic groups are of fundamental importance in hybrid crop breeding. This study investigated hybrid yield, yield heterosis and combining ability within and among groups based on genetic distance derived from single ...

A unified framework for hybrid breeding and the establishment of heterotic groups in wheat
Theoretical and Applied Genetics, 2016Global wheat genetic diversity can be used in a unified framework to support and accelerate hybrid breeding and the development of heterotic groups in wheat. Hybrid wheat breeding has great potential to increase the global wheat grain yield level particularly in view of the increasing abiotic and biotic stress challenges as well as variable climatic ...

Determination of heterotic groups for tropical Indica hybrid rice germplasm
Theoretical and Applied Genetics, 2013Two heterotic groups and four heterotic patterns were identified for IRRI hybrid rice germplasm to develop hybrid rice in the tropics based on SSR molecular data and field trials. Information on heterotic groups and patterns is a fundamental prerequisite for hybrid crop breeding; however, no such clear information is available for tropical hybrid rice ...

Genetic diversity trends in Central European heterotic groups
Acta Agronomica Hungarica, 2006It has been claimed that the system that delivers the products of plant breeding reduces the diversity of cultivated varieties, leading to increased genetic vulnerability. The objective of our study was to monitor the temporal trends in genetic diversity over the past five decades among maize cultivars with the largest acreage in Central Europe. Thirty
