  • Since the 70's the IPP-CNR has been dealing with cypress breeding program for resistance to Seiridium bark canker. To carry out such a program, a copious body of plant material has been collected in native ranges of 23 cypress species and maintained ex situ in a series of experimental fields as clones and half-sib progenies of selected mother plants. More than 4200 Cupressus sempervirens clones are maintained in the archive; hundreds are the half-sib plants obtained from candidates selected in some Greek and Turkish native populations and many thousands the plants of FI, F2, 51, 52 progenies obtained from intra-specific controlled crosses and backcrosses. Thousands of inter-specific hybrids are also kept in the archives. This wide genetic base has been created to make studies on the inter- and intra-specific variability of the response to bark canker within the genus Cupressus, on the main genetic parameters and stability of canker resistance and on the host-pathogen-environment interaction. Important studies were also conducted on genetics, botany, inter-specific compatibility, tolerance, stability, phenotypic plasticity, allergology. Among the main results, hundreds of C. sempervirens canker resistant clones were selected to date; 8 of them were patented to be used for ornamental or windbreak plantings. A set of parent clones was selected to set up clonal orchards assigned to the large-scale production of improved seeds for reforestation. In the course of the last decade, comparative fields have been set up in various Mediterranean regions with many canker resistant cypress clones characterized by a wide crown shape to evaluate their aptitude for being used as windbreaks, recovering of marginal lands, and for protection against emerging natural risks such as erosion, desertification and forest fires.

Abstract
  • Since the 70's the IPP-CNR has been dealing with cypress breeding program for resistance to Seiridium bark canker. To carry out such a program, a copious body of plant material has been collected in native ranges of 23 cypress species and maintained ex situ in a series of experimental fields as clones and half-sib progenies of selected mother plants. More than 4200 Cupressus sempervirens clones are maintained in the archive; hundreds are the half-sib plants obtained from candidates selected in some Greek and Turkish native populations and many thousands the plants of F1, F2, S1, S2 progenies obtained from intra-specific controlled crosses and backcrosses. Thousands of inter-specific hybrids are also kept in the archives. This wide genetic base has been created to make studies on the inter- and intra-specific variability of the response to bark canker within the genus Cupressus, on the main genetic parameters and stability of canker resistance and on the host-pathogen-environment interaction. Important studies were also conducted on genetics, botany, inter-specific compatibility, tolerance, stability, phenotypic plasticity, allergology. Among the main results, hundreds of C. sempervirens canker resistant clones were selected to date; 8 of them were patented to be used for ornamental or windbreak plantings. A set of parent clones was selected to set up clonal orchards assigned to the large-scale production of improved seeds for reforestation. In the course of the last decade, comparative fields have been set up in various Mediterranean regions with many canker resistant cypress clones characterized by a wide crown shape to evaluate their aptitude for being used as windbreaks, recovering of marginal lands, and for protection against emerging natural risks such as erosion, desertification and forest fires.
