Para atender a demanda por material genetico resistente a essa doenca, foram avaliados, durante os anos de 1994/95, 36 clones de cupuacuzeiro, plantados no Campo Experimental da Embrapa Amazonia Orienta, em Belem, PA. Na avaliacao de 1995, cerca de 78% dos clones ja apresentavam sintomas da doenca. Observou-se grande viabilidade entre clones para o carater numero medio de vassouras emitidas por planta. Dos clones em teste, oito nao apresentaram nenhum sintoma da doenca. |

Forage legumes from the genus Stylosanthes are frequently used as pasture cover crops with positive effects in controlling weeds, soil fertility and crop yield while providing livestock feed and additional income for farmers through seed production.
Stylosanthes guianensis is native to South America and extensively grown worldwide. Therefore, efforts to improve this species may help the sustainability of livestock production in pasture areas managed with this legume. We evaluated 12 sister lines
spread through seeds under clippings in the western Amazon region, Brazil. The results were analysed using the methodology of mixed models. Five sister lines mixed with the grass Brachiaria brizantha were evaluated under continuous grazing
for two consecutive years. We estimated the genetic and phenotypic parameters of the forage legume and then identified and validated, under grazing, the sister lines most promising to be used in an area of the western Brazilian Amazon. Total drymatter
yield, soil coverage, height before clipping, height after clipping and seed production showed low‐to‐moderate broad‐sense heritability (0.1?0.5), contrasting with reduced genetic variability for the characters associated with nutritive value. The S. guianensis lines had, on average, 278 g/kg of crude protein in the dry matter of the leaves and 200 g/kg in the stems, suggesting that the use of this species may help to overcome the low protein content of tropical pastures. There are promising stylo lines that can be used in mixed pastures in humid tropical regions.
