Efficiency of physiological tools in tropical maize breeding for yield potential and stress tolerance

Description of the topic

This research topic would investigate the selection efficiency of data derived from proximal and remote sensing (indirect selection) versus direct selection for grain yield in a range of environments (optimal, drought and low nitrogen stress). The student would assist in the collection of field data over one season and have access to previous data to allow her/him to determine if any data from proximal or remote sensing tools combined with grain yield could increase selection efficiency in tropical maize breeding programs compared to selecting for grain yield alone.

Work expectations

The candidate is expected to be strong in data analysis and able to use selection indices to compare probable gains obtained through indirect and direct selection for grain yield. A solid understanding of breeding and quantitative genetics is required, along with an understanding of stress physiology. The data available to the student are sufficient for publication in a peer-reviewed journal; therefore, he/she would be expected to develop a publication based on the results.

Required skills

Knowledge of statistical analysis and plant breeding.
