Its control is based upon integration of several cultural practices associated with chemical control, and growing resistant cultivars. In order to do that, Embrapa Cassava & Tropical Fruits is carrying out a pineapple breeding program aimed at obtaining fusariosis resistant cultivars. Up to the present that breeding program has generated and evaluated 53,397 hybrids. Among them, the hybrid PE × SC-56, that showed good quality fruits, besides being resistant to fusariosis, was released as a new pineapple cultivar in 2003, named ?Imperial?, and was recommended for planting mainly in regions where that disease is one of the main limiting factors for pineapple production. The ?Imperial? pineapple plant is of intermediate height with spineless dark green leaves. The fruit is small and cylindrical, with a yellow peel at ripening. The pulp is yellow, with a high sugar content, moderate acidity, a high level of ascorbic acid and a very good flavor. ?Imperial? also shows resistance to internal browning. The following characteristics may be considered as unfavorable: slow plant growth, peduncle with small diameter, small fruit (1.6 kg), rough fruit surface due to uneven fruitlets (influenced by climatic conditions), slips occasionally attached to the fruit base. Growing "Imperial" pineapple does not require fungicide applications to control fusariosis, thus resulting in reduction of production costs, lower environmental impact and safer fruit production.  aplant breeding  aAnanas comosus var  acomosus  aResistant variety1 aMATOS, A.
