Abstract - An experiment of a factorial structure of threee genetic potentials fõr mature size (WMA) (30, 40 and 50kg of body weight) by three genetic potentials for rnilk production (MIILK) (1.125, 1.500, and 1.875kg of milk x ewe x day 1 at the peak day of lactation) by three genetic potentials for ovulation rate (Ova) (1.65, 2.20 and 2.75 ova x o.vulation') in a total of 27 genotypic combinations were simulated. Simulation results showed efficiency of sheep meat production for Northeast Brazil (total weight sold x ton of dry matter consumed hy the flocC 1 x year) increased with increases in genetic potential for ovulation rate and with increases in genetic potential for milk production, but it decreased with increases in genetic potential for inature size. The most efficient genotype was the one wJ.th medium WMA, medium MILK or high OVR, followed closely by the genotypes with medium WMA, low MILK and high OVR, and by low WMA, ruedium MILK and high OVR. High WMA genotyps were not present in the eleven genotype combinations ranked above the base genotype. [Genótipos potenciais para ovinos Morada Nova]. REsumo - Foi conduzido um experimento simulado com desenho em estrutura fatorial com tres potenciais geneticos para tamanho a maturidade (WMA) (30, 40 e 50Kg de peso vivo), tres potenciais geneticos para producao de leite (MILK) (1,125. 1,500 e 1,875Kg de leite X dia -1 X ovelha no pique de lactacao -1) e tres potenciais geneticos para taxa de ovulacao (OVR) (1,65, 2,20 e 2,75 ovulos X ovulacao -1) num total de 27 combinacoes genotipicas. Os resultados da simulacao mostraram que a eficiencia de producao de carne ovina no Nordeste do Brasil (peso total comercializado X materia seca total consumida pelo rebanho -1 X ano -1) aumenta com aumentos no potencial genetico para producao de leite, mas diminui com aumentos no potencial genetico para peso a maturidade. O genotipo mais eficiente foi aquele com WMA medio, MILK medio e alta taxa de ovulacao seguido de perto por genotipos com medio WMA, baixo MILK e alto OVR e por baixo WMA, medio MILK e alto OVR. Genotipos com alto WMA nao apareceram na lista das onze combinacoes genotipicas superiores as genotipo base.

ABSTRACT: Sudden death syndrome (SDS) caused by the soilborne fungus Fusarium solani f. sp. glycine (FSG) is a major disease in soybean [Glycine max (L.) Merr.]. Slecetion for SDS resistance in the field is difficult because of the impact of the environment on disease development. The objective of my first study was to evaluate the effect of field inoculation methods, soil compaction, and irrigation timing on the occurrence of SDS symptons. Six treatments which included FSG infested grain of white sorghum [Sorghum bicolor (L.) Moench], popcorn (Zea mays everta) or oat (Avena sativa L.) were planted in the furrow with the soybean seed, broadcasted and incorporated into the soil prior to planting or placed below the soybean seed just prior to planting. Three experiments were also conducted to evaluate the effect of compaction and irrigation on SDS symptom occurrence. Irrigation treatments that included water application at V3, V7, R3, R4 and/or R5 growth stages were applied. In all experiments disease incidence (DI) and disease severity (DS) ratings were taken to evaluate foliar SDS symptom and a disease index (DX) was determined. The inoculation methods that produced the most severe foliar symptom included placing infested sorghum below the seed prior to planting (DX=36.1) and planting infested popcorn in the furrow with the soybean seed (DX=28.7). No significant effects of soil compaction on SDS foliar symptom development were observed. The irrigation treatments during mid to late reproductive growth stages resulted in the greatest increases in SDSfoliar symptom development. Evaluation of a great number of lines for SDS resistance in the field is time consuming and expensive. The objective of the second study was to evaluate two SDS greenhouse screening methods and determine which best correlates with field resistance of soybean genotypes. Three sets of genotypes were previously evaluated for field reaction to SDS. All three sets were evaluated with the greenhouse cone method and two sets were evaluated with the greenhouse tray method...
