| Abstract:
In the Ribeira River Valley in the State of São Paulo, the main region for anthurium production in Brazil, until now seed-propagated plants grown from crosses made by the growers themselves predominated production. The characteristics of these plants and their flowers are heterogeneous. In recent years, the Instituto Agronômico in Campinas (IAC) released 12 varieties mostly for cut flower production. Only 11 named varieties are listed under the list of existing selections. They are multiplied in vitro by private laboratories and then transferred to the growers. The breeding program on anthurium at the Instituto Agronômico aims to select vigorous and productive plants, with good quality flowers, mainly for cut flower production for the Brazilian market and possibly for future export. Hybrids are selected from among thousands of seedlings obtained from cross-pollination of selected plants from the collection of the Instituto Agronômico, at the Ribeira River Valley Experimental Station. Hybrids were cultivated in beds of organic soil under 70% shade net in an spray irrigated house, where they have been observed monthly for many years under low levels of pesticide use. After more than 20 years of selection, selection criteria have been established for IAC varieties, which have resulted in selections that perform well under a broad amplitude of temperature conditions (from 3 to 38ºC). Selections with these characteristics are very welcome in times of controlled, organic production and high energy costs for controlled-climate greenhouses. In this report, we also present brief descriptions of 12 new Anthurium selections, which are named for Brazilian Indian tribes. | |
