Paleo-Green Revolution for rice

Paleo-Green Revolution for rice.

A central element of the Green Revolution was the widespread adoption of semidwarf rice cultivars (SRCs) that more than doubled worldwide rice production (1). The high-yield potentials of modern SRCs are attributed primarily to their improved harvest index, lodging resistance, and responsiveness to high inputs (primarily nitrogen and water) (1–3), contributing to their adoption in irrigated are...

The Doubly Green Revolution in Rice

It is indeed a pleasure to be at this World Food Prize celebration here in Des Moines to participate in honoring this year’s co-laureates, Dr. Monty Jones and Prof. Yuan Longping, two giants in rice research. How appropriate it is that we honor them this year—2004, the International Year of Rice. In Africa and Asia, respectively, they have both made remarkable contributions toward the eradicati...

Genealogy of the "Green Revolution" gene in rice.

During the "Green Revolution" of rice, high-yielding varieties (HYVs) were developed using a semi-dwarf gene (sd1 or OsGA20ox2). The presence or absence of the two mutant alleles (DGWG type in Dee-geo-woo-gen and JKK type in Jikkoku) were surveyed by PCR using 256 accessions of eight wild and two cultivate rice species. The DGWG allele was detected in a landrace (Oryza sativa) and two accession...

The Green Revolution Revisited

Introduction It is a great pleasure to be here in Oslo, nearly 30 years after I was awarded the Nobel Peace Prize. I wish to thank the Norwegian Nobel Institute and the U.S. Embassy in Norway for arranging this lecture. Today, I am here to take stock of the contributions of the so-called “Green Revolution,” and explore the role of science and technology in the coming decades to improve the quan...
