Title: Insight on time-series phenotyping of rice in the field using UAVs

Plant Research Centre Auditorium, 28 March, 3:00 pm – 4:00 pm

Maximising crop yield is one of the main interests of agricultural researchers. My team is carrying out research on how growth pattern is effective in producing rice yield. We developed the method for time-series data on vegetation fraction (VF) as a vegetation index and canopy height (CH) as a vertical growth parameter in rice using UAVs. Using the method, we detected QTLs for VF and CH through genetic analysis using our multiparent advanced generation intercross (MAGIC) lines and showed the relevance of the QTLs for yield-related traits. I would like to share the progress of my recent work and discuss the use of high-throughput phenotyping data.
