ABSTRACT.
The whitefly-transmitted Tomato chlorosis virus (ToCV) (genus Crinivirus) is associated with yield and quality losses in field and greenhouse-grown tomatoes (Solanum lycopersicum) in South America. Therefore, the search for sources of ToCV resistance/tolerance is a major breeding priority for this region. A germplasm of 33 Solanum (Lycopersicon) accessions (comprising cultivated and wild species) was evaluated for ToCV reaction in multi-year assays conducted under natural and experimental whitefly vector exposure in Uruguay and Brazil. Reaction to ToCV was assessed employing a symptom severity scale and systemic virus infection was evaluated via RT-PCR and/or molecular hybridization assays. A subgroup of accessions was also evaluated for whitefly reaction in two free-choice bioassays carried out in Uruguay (with Trialeurodes vaporariorum) and Brazil (with Bemisia tabaci Middle-East-Asia-Minor1?MEAM1 = biotype B). The most stable sources of ToCV tolerance were identified in Solanum habrochaites PI 127827 (mild symptoms and low viral titers) and S. lycopersicum ?LT05? (mild symptoms but with high viral titers). These two accessions were efficiently colonized by both whitefly species, thus excluding the potential involvement of vector-resistance mechanisms. Other promising breeding sources were Solanum peruvianum (sensu lato) ?CGO 6711? (mild symptoms and low virus titers), Solanum chilense LA1967 (mild symptoms, but with high levels of B. tabaci MEAM1 oviposition) and Solanum pennellii LA0716 (intermediate symptoms and low level of B. tabaci MEAM1 oviposition). Additional studies are necessary to elucidate the genetic basis of the tolerance/resistance identified in this set of Solanum (Lycopersicon) accessions.

Uruguayan meat production systems are based mainly on grazing pastures. More intensive systems have been growing by adding concentrate to grazing animals to improve performance and beef carcass and meat quality. Thirty two Hereford steers of 20 months of age, were randomly assigned to 4 treatments as a result of combining 2 levels of forage allowance (LFA: 2% and 4% of live weight LW) and supplementation (S: 0.8 and 1.6 % of ground sorghum), where: T1 = 4 % LFA + 0 % S; T2 = 2 % LFA + 0 % S; T3 = 2 % LFA + 0.8 % S and T4 = 2 % LFA + 1.6 % S. Steers from T1 and T4 produced heavier carcasses (HCW) and higher back fat thickness (BFT). When HCW is adjusted by final live weight (FLW) the differences disappeared, showing that differences were due basically for different final weight. Same tendency was observed for the weight of the most valuable meat cuts. Treatments did no affect (P>0.05) ultimate pH, intramuscular fat, meat color at 48 hours after slaughter, tenderness of meat aged for 7 and 20 days. No treatment differences on PUFA concentration and PUFA/SFA and n6/n3 ratio were found. However, meat of T4 animals presented the higher concentration of MUFA, particularly oleic fatty acid. Meat of treatments based only on pasture (T1 and T2) presented the higher concentration of linolenic and stearic fatty acids. Meat produced on grass-fed or combined with low supplement levels, could promote human health. |
