Abstract ? The objective of this work was to identify genotypes with high general combining ability for resistance to witches'-broom (Moniliophthora perniciosa) in populations formed from a first cycle of recurrent selection. Highly productive and resistant clones from different origins were interbred using the North Carolina II design. The clones SCA 6, CSUL 7, RB 39, CEPEC 89, OC 67, BE 4, EEG 29 and ICS 98 were used as paternal parents, while the maternal ones were NA 33, CCN 10, IMC 67, P 4B, CCN 51, CEPEC 86, SGU 54 and ICS 9. Twenty days after germination, 56 seedlings of each cross (four replicates of 14 seedlings) received the inoculation of a 1-mL suspension with 7.5x104 basidiospores mL?1. Symptoms were evaluated 60 days after inoculation....

Weevil associated to gummosis in oil palm (Elaeis guineensis Jacq.) in Brazil. Repositório Alice
MOURA, J. I. L.; OLIVEIRA, M. L. de; LUZ, E. D. M. N.; SILVA, S. D. V. M.; SANTOS, R. S..
In commercial plantations of oil palm in Nazare municipality, state of Bahia, Brazil, the association of Rhinostomus barbirostris Fabricius and Ceratocystis paradoxa (Dade) C. Moreau in high number of oil palm trees showing stem bleeding symptoms was observed. The pathogen was isolated from tissues of diseased oil palm plants. To our knowledge this is the first report on the contribution of R. barbirostris to increase the severity of stem bleeding disease caused by C. paradoxa in oil palm. Control measures are suggested.
