Selection of CTV-tolerant citrus hybrids for ornamental use

Abstract

-Introduction.Ornamental citrus is well established in Europe and North America, but is still incipient in Brazil, despite the fact that the country is among the world's leading citrus fruit producers. However, the potential for innovation in this agribusiness segment is increasingly recognized. The Citrus Breeding Program of Embrapa Cassava & Fruits, among other objectives, aims to create plants suitable for ornamental use. Materials and methods. Ten hybrids were characterized by application of 39 morphological descriptors to identify their ornamental potential and to classify them in use categories. Additionally, these hybrids were evaluated regarding their susceptibility to the citrus tristeza virus (CTV).
