ABSTRACT
Rice breeding has made important contributions to Latin America. More than
400 cultivars were released from 1975 to 2012, which helped to raise total
production to
>
27 million tonnes obtained from 5.7 million hectares (average
for 2010
US$8.8 billion for thousands of
farmers in Latin America and the Caribbean (LAC). The result of higher yields
in the irrigated sector was to triple rice production in LAC while area did not
grow, thus preserving more fragile environments. Several estimates on genetic
gains for grain yield have been carried out in LAC. In temperate irrigated rice,
the estimates are around 1.5
