Heterobeltiosis in Banana and Genetic Gains through Crossbreeding [PDF]

open access: yesThe Third International Tropical Agriculture Conference (TROPAG 2019), 2020
Heterosis, or hybrid vigour, is the superiority of the hybrid for a certain trait over the mean of its two parents. Heterobeltiosis is a form of heterosis where the hybrid is superior to its best parent. Banana breeding is a tedious, time-consuming process, taking up to two decades to develop a hybrid.

Selection and Genetic Gain in Third-generation Seedling Seed Orchard of Acacia Mangium [PDF]

open access: yes, 2017
One of the purposes of seedling seed orchard (SSO) establishment is to produce genetically improved seeds. The amount of genetic gain in the SSO is determined from a series of selection involving within and between family selection in which the gain is ...

Genetic optimization of Brillouin scattering gain in subwavelength-structured silicon membrane waveguides [PDF]

open access: yes, 2023
On-chip Brillouin optomechanics has great potential for applications in communications, sensing, and quantum technologies. Tight confinement of near-infrared photons and gigahertz phonons in integrated waveguides remains a key challenge to achieving strong on-chip Brillouin gain.

Expected Genetic Contributions and Their Impact on Gene Flow and Genetic Gain [PDF]

open access: yesGenetics, 1999
Abstract Long-term genetic contributions (ri) measure lasting gene flow from an individual i. By accounting for linkage disequilibrium generated by selection both within and between breeding groups (categories), assuming the infinitesimal model, a general formula was derived for the expected contribution of ancestor i in category q (μi(q)

The effect of genomic information on optimal contribution selection in livestock breeding programs [PDF]

open access: yes, 2013
BACKGROUND: Long-term benefits in animal breeding programs require that increases in genetic merit be balanced with the need to maintain diversity (lost due to inbreeding). This can be achieved by using optimal contribution selection. The availability of

Tendências genéticas para características relacionadas à velocidade de crescimento em bovinos Nelore na região nordeste do Brasil Genetic trends for traits related to the growth rate in Nellore cattle raised in the Northeast region of Brazil

open access: yesRevista Brasileira de Zootecnia, 2005
Foram estimados os parâmetros e as tendências genéticas dos efeitos direto e materno na característica dias para ganhar 160 kg (D160) na fase pré-desmama e do efeito direto na característica dias para ganhar 240 kg (D240) na fase pós-desmama, em bovinos ...

Multistage selection for genetic gain by orthogonal transformation. [PDF]

open access: yesGenetics, 1991
Abstract An exact transformed culling method for any number of traits or stages of selection with explicit solution for multistage selection is described in this paper. This procedure does not need numerical integration and is suitable for obtaining either desired genetic gains for a variable proportion selected or optimum aggregate ...

Breeding techniques to dispense higher genetic gains

open access: yesFrontiers in Plant Science, 2023
Plant breeding techniques encompass all the processes aimed at improving the genetic characteristics of a crop. It helps in achieving desirable characteristics like resistance to diseases and pests, tolerance to environmental stresses, higher yield and improved quality of the crop.
