Recurrent phenotypic selection and recurrent selection based on combining ability in tetraploid bahiagrass [PDF]

open access: yesCrop Science, 2020
AbstractPaspalum notatum Flüggé is an apomictic grass used for forage and turf. The recent generation of a sexual synthetic tetraploid population of the species provides the unique advantage to exploit heterosis by accumulating favorable alleles through recurrent selection cycles.

Recurrent selection in inbred popcorn families [PDF]

open access: yesScientia Agricola, 2004
Although much appreciated in Brazil, commercial popcorn is currently cropped on a fairly small scale. A number of problems need to be solved to increase production, notably the obtaintion of seeds with good agronomic traits and good culinary ...

Selection Mapping Identifies Loci Underpinning Autumn Dormancy in Alfalfa (Medicago sativa). [PDF]

open access: yes, 2018
Autumn dormancy in alfalfa (Medicago sativa) is associated with agronomically important traits including regrowth rate, maturity, and winter survival. Historical recurrent selection experiments have been able to manipulate the dormancy response.

Selective interstitial doxorubicin for recurrent glioblastoma [PDF]

open access: yesClinical Case Reports, 2019
AbstractPoor delimitation from the viable brain, great genetic heterogeneity, lack of tumor vascularisation are factors that preclude intravenous chemotherapy. Interstitial chemotherapy could be a strategy to avoid a blood‐brain barrier and to assure a minimal dose concentration of the chemotherapy agent.

Nutritional Security in Drylands: Fast-Track Intra-Population Genetic Improvement for Grain Iron and Zinc Densities in Pearl Millet

open access: yesFrontiers in Nutrition, 2019
Considering the pervasive malnutrition caused by micronutrients, particularly those arising from the deficiencies of iron (Fe) and zinc (Zn), the primary focus of research in pearl millet is on biofortifying the crop with these two minerals. Pearl millet

Robust forward simulations of recurrent hitchhiking [PDF]

open access: yes, 2014
Evolutionary forces shape patterns of genetic diversity within populations and contribute to phenotypic variation. In particular, recurrent positive selection has attracted significant interest in both theoretical and empirical studies.

THEORETICAL MODIFICATIONS OF RECIPROCAL RECURRENT SELECTION [PDF]

open access: yesGenetics, 1976
ABSTRACT Reciprocal recurrent selection (RRS), which assumes overdominant loci to be important, alters two genetically different populations to improve their crossbred mean. Individual plants from two populations (A and B) are selfed and also crossed with plants from the reciprocal female tester population (B and A, respectively ...

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.
