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 2010-2012). Rice production provides ~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 1.5-2.6% per year. In the tropical irrigated, it is ~1% and in the upland rice the estimate is ~1.4% per year.
Different breeding strategies, including pedigree, modified bulk, recurrent selection methods, anther culture, interspecific crosses, composite populations, quantitative trait loci (QTL) introgression, and recombinant inbred lines, accompanied by shuttle breeding schemes, direct seeding, and evaluation/selection in hot spots for main diseases are being used by CIAT and NARES in the region. In this process, methods for screening for diseases and other stresses were established. Networking has been a cornerstone for success and several networks such as INGER, FLAR, and HIAAL were created.
Looking forward, as farmers' yields are approaching the genetic yield potential exhibited by current cultivars, as a result of improved agronomic management, a new breakthrough is needed in terms of more productive cultivars. To achieve this goal, a strategy is needed that includes strong pipelines focused on specific environments and markets; better product profiling; integration between discovery, development, and delivery; and new breeding strategies using cutting-edge technologies and new breeding methods to accelerate genetic gains.

ABSTRACT.
Variations in phenotypic expression of feed efficiency could be associated with differences or inefficiencies in mitochondria function due to its impact on energy expenditure. The aim of this study was to determine hepatic mitochondrial density and function in terms of respiration, gene and protein expression, and enzyme activity of mitochondrial respiratory complex proteins, in steers of divergent residual feed intake (RFI) phenotypes. Hereford steers (n = 111 and n = 122 for year 1 and 2, respectively) were evaluated in postweaning 70 d standard test for RFI. Forty-six steers exhibiting the greatest (n = 9 and 16 for year 1 and 2; high-RFI) and the lowest (n = 9 and 12 for year 1 and 2; low-RFI) RFI values were selected for this study. After the test, steers were managed together until slaughter under grazing conditions until they reached the slaughter body weight. At slaughter, hepatic samples (biopsies) were obtained. Tissue respiration was evaluated using high-resolution respirometry methods. Data were analyzed using a mixed model that included RFI group as fixed effect and slaughter date and year as a random effect using PROC MIXED of SAS. RFI and dry matter intake were different (P < 0.001) between low and high-RFI groups of year 1 and year 2. Basal respiration and maximum respiratory rate were greater (P ? 0.04) for low than high-RFI steers when complex II substrates (succinate) were supplied. However, when Complex I substrates (glutamate/malate) were used maximum respiratory capacity tended to be greater (P < 0.09) for low vs. high-RFI steers. Low-RFI steers presented greater mitochondria density markers (greater (P < 0.05) citrate synthase (CS) activity and tended (P ? 0.08) to have greater CS mRNA and mtDNA:nDNA ratio) than high-RFI steers. Hepatic expression SDHA, UQCRC1, and CYC1 mRNA was greater (P ? 0.02) and expression of NDUFA4, NDUFA13, SDHD, UQCRH, and ATP5E mRNA tended (P ? 0.10) to be greater in low than high-RFI steers. Hepatic SDHA protein expression tended (P < 0.08) to be greater while succinate dehydrogenase activity was greater (P = 0.04) and NADH dehydrogenase activity was greater (P = 0.03) for low than high-RFI steers. High-efficiency steers (low-RFI) probably had greater efficiency in hepatic nutrient metabolism, which was strongly associated with greater hepatic mitochondrial density and functioning, mainly of mitochondrial complex II.
