HETEROSIS OR NEUTRALITY? [PDF]

Genetics, 1977
ABSTRACT Various statistics have been proposed on an ad hoc basis to test whether alleles at a locus are selectively neutral. By considering population models in which selection operates, this paper shows that the population homozygosity is a powerful test statistic for testing departures from neutrality, in the direction of heterozygote

Is heterosis noticeable in the callus response of winter durum wheat F₁ hybrids? [PDF]

, 2010
The effect of heterosis on callus induction, callus mass and number of regenerated plants from mature embryo cultures of winter durum wheat (Triticum durum Desf.) hybrids was studied. A total of 14 F1 hybrids and their parents were used for mature embryo

Heterosis analysis of 401 hybrids. [PDF]

, 2023
Mid-parent value is the average best linear unbiased estimates (BLUE) of mesocotyl length of parents of the hybrids. d-value is the difference of BLUE between hybrid and its mid-parent value.

Dissection of two QTL clusters underlying yield-related heterosis in the cabbage founder parent 01–20

Horticultural Plant Journal, 2023
Cabbage has significant heterosis and most commercial cultivars are hybrids. To explore genetic basis of cabbage heterosis and promote cabbage heterosis utilization, we constructed two populations by crossing 100 DH lines derived from a cabbage hybrid 01–

The role of epistasis in the manifestation of heterosis: a systems-oriented approach [PDF]

, 2007
Heterosis is widely used in breeding, but the genetic basis of this biological phenomenon has not been elucidated. We postulate that additive and dominance genetic effects as well as two-locus interactions estimated in classical QTL analyses are not ...

Genome-Wide Identification and Expression Analysis of TUA and TUB Genes in Wheat (Triticum aestivum L.) during Its Development

Plants, 2022
Microtubules play a fundamental role in plant development, morphogenesis, and cytokinesis; they are assembled from heterodimers containing an α-tubulin (TUA) and a β-tubulin (TUB) protein.

Biomass heterosis as the basis for grain and stover yield heterosis in arid zone pearl millet hybrids [PDF]

, 2009
Pearl millet [Pennisetum glaucum (L.) R. Br.] single cross hybrids, bred from high-yielding parental lines in favorable environments, are not well adapted to northwest India's arid zone.

Heterosis in cowpealandraces from Ghana [PDF]

, 1999
Four crosses involving five local accessions of cowpea were evaluated to determine the amount of heterosis for maturity date, seed yield, and components of yield.
