Estimate of genetic parameters in Brachiaria decumbens hybrids [PDF]
Crop Breeding and Applied Biotechnology, 2016 The objective of this study was to estimate genetic parameters for agronomic traits and nutritional value in intraspecific hybrids of B. decumbens. For this, a population of 1,415 hybrids was evaluated in field plots at Embrapa Beef Cattle in Campo ...

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

Robust forward simulations of recurrent hitchhiking [PDF]
, 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.

Selective interstitial doxorubicin for recurrent glioblastoma [PDF]
Clinical 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.

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

THEORETICAL MODIFICATIONS OF RECIPROCAL RECURRENT SELECTION [PDF]
Genetics, 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 ...

Genetic gain of ‘Valenciana’ onion populations developed in the Brazilian Semi-Arid region [PDF]
Crop Breeding and Applied Biotechnology, 2017 The aim of the present study was to estimate the genetic improvement in the last recurrent selection cycles applied in two ‘Valenciana’ onion populations in Petrolina, PE.

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

Effect of recurrent selection on the variability of the UENF-14 popcorn population [PDF]
Crop Breeding and Applied Biotechnology, 2016 This study aimed to evaluate the effect of recurrent selection on the genetic variability of UENF-14 population after six selections. Two hundred and ten half-sib families were evaluated in two environments in the state of Rio de Janeiro, using ...
