Impact of nonadditive genetic effects in the estimation of breeding values for fertility and correlated traits [PDF]

, 2005
The effects of inbreeding, heterosis, recombination loss, and percentage Holstein on the estimation of predicted transmitting abilities for fertility traits (calving interval, number of days from calving to first insemination, nonreturn rate, number of ...

Heterosis analysis for grain yield traits in Maize (Zea mays L.)

Electronic Journal of Plant Breeding, 2018
In the present study 6 inbreds were used as parents to make crosses in all possible cross combination in full diallel fashion to obtain total 30 possible F1 hybrids. These 30 F1’s were subjected to heterosis analysis for midparental, heterobeltiosis and

Heterosis in the freezing tolerance of Arabidopsis thaliana (L.)Heynh [PDF]

, 2010
Die vorliegende Arbeit beschäftigt sich mit Heterosis in der Frosttoleranz von Arabidopsis-Kreuzungen. Die genetische Basis von Heterosis, der Verbesserung heterozygoter F1-Hybriden gegenüber den homozygoten Eltern, ist unbekannt.

Partial unidirectional translocation from 5AL to 7BS leads to dense spike in an EMS-induced wheat mutant

BMC Genomics
Background As the inflorescence of wheat, spike architecture largely determines grain productivity. Dissecting the genetic basis for the spike morphology of wheat can contribute to the designation of ideal spike morphology to improve grain production ...

Estimation of heterosis in pearl millet [Pennisetum glaucum (L.)] for yield and quality traits

Electronic Journal of Plant Breeding, 2016
Five CMS lines were crossed with nine testers in a line x tester design to study the extent of heterosis in pearl millet for yield and quality traits. Heterosis was observed in both directions for most of the characters.

'Heterosis' in Drosophila [PDF]

Evolution, 1963
In the course of some experiments with Drosophila melanogaster on the adaptive value of several dominant mutants in competition with their wild-type alleles, an anomalous situation arose with respect to Lobe-2. Further investigation of these results produced an explanation which raises some interesting questions about reports of heterosis in Drosophila.

A phase-shift model for heterosis. [PDF]

, 2016
ZmCCA1-regulatory networks orchestrate multiple biological pathways for growth heterosis, which is established at early stage and subsequently maintained during the seedling development. The altered temporal binding of ZmCCA1s to carbon fixation genes in

Quantitative Genetics of Heterosis [PDF]

, 1999
Nearly 50 years have elapsed since the seminal heterosis conference was held at Iowa State College (Gowen, 1952). That conference undoubtedly grew out of the obvious importance of maize (Zea mays L.) hybrids in the agricultural economy of Iowa and the ...

Translational regulation plasticity shapes wheat grain adaptation to heat stress

Genome Biology
Background Extremely high temperatures due to global warming are increasingly threatening crop production, and plants have evolved highly sophisticated mechanisms to respond to harsh environmental stresses and survive.

Heterosis and Inbreeding Depression in Glycine max [PDF]

, 2009
This study focused on soybean heterosis in regard to yield, seed size, and height and consisted of three objectives: (1) to study three new hybrids and retest a fourth hybrid for heterosis, (2) to study the correlation between heterosis in the F2 ...
