Defense heterosis as a novel plant protection strategy: From theory to breeding practice

New Plant Protection, EarlyView.
Defense heterosis, the enhanced disease resistance of hybrids compared to their parents, has evolved from early observations of hybrid vigor to a novel research concept. Advances are now clarifying its diverse genetic and molecular mechanisms across various plant–pathogen interactions.

Combination ability of new dihaploid corn lines in the conditions of the Right Bank of the Saratov region [PDF]

Известия Саратовского университета. Новая серия: Серия Химия. Биология. Экология
Dihaploid lines, or lines obtained on the basis of doubled haploids, are a valuable material for the creation of high-heterosis corn hybrids. The most eff ective method of evaluating the starting material when selecting parental couples for obtaining ...

THE THEORY AND ANALYSIS OF DIALLEL CROSSES [PDF]

Genetics, 1954
HE investigation of the properties of groups of homozygous lines by means T of diallel crosses as proposed by HULL (1945) has subsequently been discussed in growing detail in a series of papers by JINKS and HAYMAN (1953 and later). With certain assumptions, the genetic variation present can be described in terms of the biometrical concepts of MATHER ...

Structural Variations Contribute to Subspeciation and Yield Heterosis in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Yield heterosis has been extensively exploited in hybrid breeding, with intersubspecific hybrids often exhibiting the most pronounced effects. However, developing elite hybrids remains a laborious and time‐consuming process. The genetic basis of heterosis has been debated for over a century, hindered largely by the lack of high‐quality genomes.

Prediction of hybrid means from a partial circulant diallel table using the ordinary least square and the mixed model methods

Genetics and Molecular Biology, 2005
By definition, the genetic effects obtained from a circulant diallel table are random. However, because of the methods of analysis, those effects have been considered as fixed. Two different statistical approaches were applied.

Composite interval mapping and genomic prediction of nut quality traits in American and American–European interspecific hybrid hazelnuts

Crop Science, Volume 66, Issue 1, January/February 2026.
Abstract The native, perennial shrub American hazelnut (Corylus americana) is cultivated in the US Midwest for its significant ecological benefits, as well as its high‐value nut crop. Genetic improvement of perennial crops involves long‐term breeding efforts, and benefits from the use of genetic data in selection to reduce breeding cycle time.

Combining ability as a function of inbreeding for fruit traits in Cucurbita moschata Duch. ex Poir.

Revista Facultad Nacional de Agronomía Medellín, 2019
Three diallel crosses of butternut squash (Cucurbita moschata), each consisting of six parents with S0, S1, and S2 levels of inbreeding, were evaluated to estimate the effect of inbreeding on both general (GCA) and specific combining abilities (SCA) for ...
