Methods of recurrent selection and exploitation of heterosis in maize [PDF]

open access: yesSelekcija i Semenarstvo, 2004
Recurrent selection methods were designed to improve the agronomic value of populations by gradually increasing the frequency of favorable alleles, while maintaining genetic variability.

Effects of Recurrent Selection on Population Structure and Allele Frequencies in the M3S Maize Population

open access: yesAgriculture, 2023
The effects of four cycles of recurrent selection on the allele frequencies of simple sequence repeat (SSR) markers and population structure were examined in the Maksimir 3 Synthetic (M3S) maize population (Zea mays L.). Genotyping of 32 plants from each

Soft sweeps III: The signature of positive selection from recurrent mutation [PDF]

open access: yes, 2006
Polymorphism data can be used to identify loci at which a beneficial allele has recently gone to fixation, given that an accurate description of the signature of selection is available. In the classical model that is used, a favored allele derives from a

A Decade of Variety Testing for Resistance of Red Clover to Southern Anthracnose (Colletotrichum trifolii Bain et Essary) at the Bavarian State Research Center for Agriculture (LfL)

open access: yesAgriculture, 2022
Southern anthracnose is caused by the fungal pathogen Colletotrichum trifolii Bain et Essary and affects red clover (Trifolium pratense) cultivation, causing severe losses in plant stands.

Utilizing Genomic Selection for Wheat Population Development and Improvement

open access: yesAgronomy, 2022
Wheat (Triticum aestivum L.) breeding programs can take over a decade to release a new variety. However, new methods of selection, such as genomic selection (GS), must be integrated to decrease the time it takes to release new varieties to meet the ...

Strategies for the next cycles of intrapopulation improvement of sour passion fruit [PDF]

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental, 2022
In breeding programs, the identification of genetic variability and knowledge of genetic constitutions existing within segregating populations are of fundamental importance for the success and continuation of the program.

Estimadores de componentes de variância em delineamento de blocos aumentados com tratamentos novos de uma ou mais populações Estimators of variance components in the augmented block design with new treatments from one or more populations

open access: yesPesquisa Agropecuária Brasileira, 2001
O objetivo do trabalho foi comparar, por meio de simulação, as estimativas de componentes de variância produzidas pelos métodos ANOVA (análise da variância), ML (máxima verossimilhança), REML (máxima verossimilhança restrita) e MIVQUE(0) (estimador ...

Sequential feature selection for classification [PDF]

open access: yes, 2011
In most real-world information processing problems, data is not a free resource; its acquisition is rather time-consuming and/or expensive. We investigate how these two factors can be included in supervised classication tasks by deriving classication ...

Acacia koa seedling disease tolerance and vigor driven by breeding orchard size

open access: yesFrontiers in Plant Science
Acacia koa Gray (koa) is a Hawaiian endemic tree species that has a long history of use in the islands. In the late 20th century disease started impacting native koa stands, leading to the initiation of seed orchards that were founded from seeds ...

Endometrial stromal cells of women with recurrent miscarriage fail to discriminate between high- and low-quality human embryos [PDF]

open access: yes, 2012
Background The aetiology of recurrent miscarriage (RM) remains largely unexplained. Women with RM have a shorter time to pregnancy interval than normally fertile women, which may be due to more frequent implantation of non-viable embryos.
