The International Rice Research Institute (IRRI) was estab-

lished in 1960 by the Ford and Rockefeller Foundations with the

help and a pproval of the Government of the Philippines. Today

IRRI is one of 16 nonprofit international research centers sup-

ported by the Consultative Group on International Agricultural

Research (CGIAR – www.cgiar.org).

IRRI receives support from severalCGIAR members, in-

cluding the World Bank, European Union, Asian Development

Bank, International Fund for Agricultural Development,

Rockefeller Foundation, and agencies of the following govern-

ments: Australia, Belgium, Canada, People’s Republic of China,

Denmark, France, Germany, India, Islamic Republic of Iran,

Japan, Republic of Korea, The Netherlands, Norway,

Phili ppines, Portugal, Sweden, Switzerland, Thailand, United

Kingdom, United States, and Vietnam.

The responsibility for this publication rests with the Interna-

tional Rice Research Institute.

soils tolerance. In addition to these breeding

programs, our research utilizes the most ad-

vanced tools to study genetics and molecular

biology as they relate to rice breeding.

Research in the Plant Breeding, Genetics, and

Biochemistry (PBGB) Division encompasses a

broad range of activities in the continuum from

applied breeding to biotechnology and

genomics. The mission statement of the divi-

Research highlights

O Eight breeding lines and four hybrids

from PBGB breeding programs were

named as varieties in seven countries

during 2002 (Table 1).

O New plant type (NPT) lines with higher

yields, improved grain quality, and re-

sistance to diseases were identified.

O Temperate japonica breeding lines with

yields of 3-5 t ha -1 in the tropics were

developed.

O Promising rainfed lowland breeding

lines were identified through the East-

ern Indian Rainfed Lowland Shuttle

Breeding Network (EIRLSBN). Some of

these lines performed well under de-

“To conduct research and training on

germplasm improvement for increased

and sustainable yields in each of the ma-

jor rice ecoystems and develop and utilize

new tools, strategies, and knowledge of

scientific excellence.”

The core breeding programs focus on the

major rice ecosystems: irrigated, rainfed low-

land, upland, flood-prone, and temperate or

cool-elevated. Other breeding programs focus

on particular traits that cut across ecosystems,

such as nutritional improvement or adverse
