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

Variation in lentil (Lens culinaris Medik) in response to irrigation [PDF]
This study aimed to investigate the response of lentil genotypes to different water regimes, providing guide lines, through partitioning the variation, for a selection program for adaptation to irrigated conditions. The research was divided into two main

Heterosis for yield and physiological traits in chickpea (Cicer arietinum L.) [PDF]
Chickpea being a highly self pollinated crop, the scope for exploitation of hybrid vigour will depend on the direction and magnitude of heterosis, biological feasibility and the type of gene action involved.

Using genomic selection to examine subgenome dominance and epistasis in allopolyploid strawberry
Abstract Allopolyploids are organisms that possess multiple sets of chromosomes derived from distinct ancestral species, resulting in multiple subgenomes. Many important crops are allopolyploid, including wheat (Triticum aestivum), cotton (Gossypium hirsutum), coffee (Coffea arabica), and strawberry (Fragaria × ananassa).

Crop establishment in carrot (Daucus carota L.) is limited by slow seedling growth and delayed canopy closure, resulting in high management costs for weed control. Varieties with improved growth habit (i.e., larger canopy and increased shoot biomass) may

Influence of Ploidy and Genetic Background on Stress Tolerance of Intraspecific Yeast Hybrids
A large set of intraspecific yeast hybrids was constructed using two strategies that yielded series of hybrids with variable ploidy. Phenotyping of the hybrids was carried out in high‐stress media to assess the effects of ploidy and genetic background on heterosis.

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.

Accumulating alleles of resistance to white mold in common beans over 13 recurrent selection cycles
Abstract White mold, caused by Sclerotinia sclerotiorum (Lib.) de Bary, is one of the main diseases affecting common bean (Phaseolus vulgaris L.) crops. Breeding for resistance to this pathogen is challenging because it is a polygenic trait with low heritability, controlled by many genes, each contributing small to moderate effects. Recurrent selection

Partial Diallel Crosses in Incomplete Blocks
Various forms of diallel crosses play an important role in evaluating the breeding potential of genetic material in plant and animal breeding (e.g., Hinkelmann, 1975, in A Survey of Statistical Design and Linear Models, 243-269. Amsterdam: North Holland).
