ABSTRACT:
Stem rot and aggregated sheath spot are the two major stem and sheath diseases affecting rice (Oryza sativa L.) in temperate areas. A third fungal disease, sheath blight, is a major disease in tropical areas. Resistance to these diseases is a key objective in rice breeding programs but phenotyping is challenged by the confounding effects of phenological and morphological traits such as flowering time (FT) and plant height (PH). This study sought to identify quantitative trait loci (QTL) for resistance to these three diseases after removing the confounding effects of FT and PH. Two populations of advanced breeding germplasm, one with 316 tropical japonica and the other with 325 indica genotypes, were evaluated in field and greenhouse trials for resistance to the diseases. Phenotypic means for field and greenhouse disease resistance, adjusted by FT and PH, were analyzed for associations with 29,000 single nucleotide polymorphisms (SNPs) in tropical japonica and 50,000 SNPs in indica. A total of 29 QTL were found for resistance that were not associated with FT or PH. Multilocus models with selected resistance-associated SNPs were fitted for each disease to estimate their effects on the other diseases. A QTL on chromosome 9 accounted for more than 15% of the phenotypic variance for the three diseases. When resistance-associated SNPs at this locus from both the tropical japonica and indica populations were incorporated into the model, resistance was improved for all three diseases with little impact on FT and PH.

ABSTRACT.
In Uruguay, livestock production involves 65% of the family farmers and more than 70% of the total area of the country. Most family farms are cow calf systems being natural grasslands the main source of animal feed. Natural grasslands constitute low cost forage and offer several ecosystem services. In the last 10 years the number of livestock family farmers decreased drastically. In this work our hypothesis is that is possible to increase productive and economic results in natural grasslands based livestock systems by the re-design of the farming system, without deterioration or even recovering the state of the natural resources. So, the objective was to quantify the impact of the re-design of the livestock grazing systems in the Eastern Uruguay on the economic and productive results and onthe environment. The work was carried out in seven pilot farms, using the co-innovation approach. After the first year of seasonal monitoring, it is possible to detect differences in richness associated to land use, being higher in natural grasslands paddocks than in sown
pastures. Productivity and income increase of livestock grazing systems in the Eastern of Uruguay is possible through the re-design of the farming system by adjusting the stocking
rate and integrating different technologies for animal and natural grassland management. This re-design allows an efficient production system, maintaining good levels of biodiversity
and enhancing other ecosystem services. |
