A Century of Understanding and Harnessing Heterosis
Plant Breeding, EarlyView.ABSTRACT Heterosis has shaped modern plant breeding since Darwin's 19th century observations that outcrossing restores vigour lost through selfing. While 100 years old, its mechanistic basis and deployability remain actively debated. Classical models of dominance, overdominance and epistasis provided the foundation for hybrid breeding and converted ...

Estimation of efficiency of in vitro androgenesis in the production of doubled rice haploids
Зерновое хозяйство РоссииRice is an important food crop, used to feed a large portion of the world’s population. The use of in vitro anther culture makes possible to develop homozygous offspring and genetically unique material within 1–2 years.

Plant Breeding, EarlyView.ABSTRACT Doubled haploid technology accelerates the development of fully homozygous maize lines compared with conventional selfing. However, specific protocols for supersweet corn (Zea mays L. var. saccharata), particularly regarding immersion time in antimitotic solutions and temperature during chromosome doubling, remain poorly defined.

Plant Breeding, EarlyView.ABSTRACT Doubled‐haploid (DH) technology based on in vivo haploid induction has become an effective strategy for accelerating maize breeding. However, improving haploid inducer populations remains challenging because accurate estimation of haploid induction rate (HIR) requires labour‐intensive phenotypic validation, while putative HIR estimates are ...

Generation of Maize (Zea mays) Doubled Haploids via Traditional Methods [PDF]
, 2017 Commercial maize hybrid production has corroborated the usefulness of producing inbred lines; however, the delivery of new lines has always been a major time constraint in breeding programs.

, 1991 Populations of doubled haploids were produced by culturing microspores from spring barley cv. Tweed, cv. Tyne, and cv. Natasha, on media containing either sucrose or maltose as the only carbohydrate. The populations were analysed for evidence of genetic

Plant Breeding, EarlyView.ABSTRACT Unreduced gametes naturally promote polyploidization and are valuable in breeding polyploid offspring. Bigleaf hydrangea (Hydrangea macrophylla ssp. macrophylla), a major ornamental crop, has shown spontaneous polyploidization rates ranging from 0% to 94% in previous crosses.

Plant, Cell &Environment, EarlyView.ABSTRACT Brassica napus (canola) is a significant contributor to the world's oil production and is cultivated across continents, yet acidic soils with aluminium (Al3+) and manganese (Mn2+) toxicities limit its production. The genetic determinants underlying natural variation for acidic soil tolerance in canola are unknown and need to be determined ...

Legume Science, Volume 8, Issue 4, December 2026.ABSTRACT Cowpea (Vigna unguiculata L. Walp) is a multi‐use crop highly valued as a food crop, high‐protein fodder, and sustainable cover crop. Yet, it remains underused, and yields in most growing regions are below the crop's potential due to multiple biotic and abiotic stresses.
