How long can rice seeds stay alive for?
Senior Scientist-Genetic Resource Specialist
T.T. Chang Genetic Resources Center (TTCGRC)
Seed longevity is an important trait for anyone involved in storing and using seeds: farmers/growers, seed companies, breeders, or genebank managers.
In this seminar, Dr Hay will present some of the theory around seed longevity, how we can make predictions depending on the initial quality of the seeds and the storage environment, and how this might be useful for genebank management.
However, looking at the genebank’s routine viability monitoring data of seed lots of genebank accessions regenerated at IRRI between 1980 and 2002, it appears that the overall storage potential has declined since the early 1990s. The potential causes of this decline, including pre- and postharvest factors, which are known to influence seed quality, will be discussed.
So don't miss it!
The IRRI seminar committee continues to encourage IRRI staff members to present seminars about their work. When preparing the PowerPoint for the seminar, staff members are encouraged to download and use the standard IRRI PowerPoint template. Also, shortly after most seminars have concluded, the audio file and PowerPoint file from the presentation will be available on a special Google Drive, accessible to staff at HQ and in the country offices.
IRRI seminars are also a forum for invited guests to present information and their opinions on topics relevant to international rice research and the work of IRRI. Speakers at IRRI Seminars are guests of IRRI and we encourage you to welcome them in every way and engage in polite and constructive discussions with them.
If you have a guest visiting from overseas, or know someone else, who you think would be a suitable candidate to give an IRRI seminar, please email the IRRI seminar committee chair, , to see if they can be fitted into the schedule. The IRRI seminar committee would like to channel all guest and special speakers into the IRRI seminars where possible and we will appreciate your help with this.
