Waite Agriculture, Food and Wine Seminar Series
Nov 28, 2019, 10:30 am
Please come along to this campus-wide seminar series. One week we will hear from a group leader or a visitor to the campus and the following week from two ECR/MCRs from the Waite Future Leaders cohort.
Come and hear about great science going on across the campus, up the road or across the sea! Expand your network and find new collaborators! Everyone is welcome to a shared morning tea (please bring your own coffee cup) following the seminar.
WHEN: Thursday 28th November 2019. 10:30am Seminar, followed by morning tea
WHERE: Plant Research Centre Auditorium
SPEAKER: Dr Daniela Bustos-Korts, Wageningen University, The Netherlands
TITLE: Genotype-to-phenotype models to increase the effectiveness of new phenotyping techniques in plant breeding
Thanks to the new phenotyping techniques it has become possible to characterize the dynamics of multiple traits over time and across environments. This opens opportunities to predict plant adaptation, facilitating the selection of well-adapted genotypes and contributing to the sustainability of agricultural systems.
Complex traits, like yield, are characterized by strong environmental context dependencies, i.e., genotype by environment interactions. Such context-dependencies make them difficult to predict and complicate the selection process for plant breeders. To assist breeders in their decision making process, the challenge is how to build genotype-to-phenotype (G2P) models that incorporate simultaneously extensive genomic information alongside with new phenotypic information.
Beyond the modification of existing G2P models, new G2P paradigms are required. We present candidate G2P models for the integration of genomic and new phenotyping information. Such models include a range of statistical models, crop growth models and networks. We describe a simulation framework combining statistical and crop growth models to create a tangible adaptation landscape that can be useful to i) study the relationships between traits over time and across environments, ii) evaluate genotype-to-phenotype models for multiple traits and environments, iii) compare models with an increased integration of statistical and biological aspects, iv) develop network models that allow visualizing how causality is propagated in biological systems and v) design efficient high throughput phenotyping schedules and methods.
About the Speaker
Daniela Bustos-Korts works as a researcher at Biometris, Wageningen University (NL). She graduated with a BSc in Agriculture and an MSc in Crop Physiology from the Universidad Austral de Chile. In 2017, she obtained her PhD from Wageningen University. Her PhD thesis was about the use of statistical and crop growth models for phenotype prediction across multiple environments. Her research interests are in the development of strategies that combine statistical and crop growth models to help breeders designing effective phenotyping and prediction schemes that will help them improving response to selection. These strategies involve the use of crop growth models like APSIM and linear mixed models for multi-trait and multi-environment genomic prediction.
