Rice Genetics Newsletter 12 (1995)
B. The Third International Rice Genetics Symposium
(sponsored by IRRl)
This symposium was held at the EDSA Plaza Hotel. Manila. 16-19, October
1995, sponsored by the IRRl with financial help by the Rockefeller Foundation.
It was held in the big hotel as the participants were over 500 and could
not be accomodated in the IRRl. On 20th October, all the participants visited
the IRRI for a full day trip.
The symposium included "plenary" (8:00-12:30 AM),
"concurrent" (in 4 separate rooms: 14:00-17:30) and "poster" (19:30-21:30
PM) sessions. In the planetary session, the following papers were
presented: (Oct. 16)M. Hossain-Economic prosperity in Asia: implications
for the demand for rice research; B. A. Antonio et. al. -High density linkage
map of rice with expressed sequence tags; O. Ideta et al. -An integrated
