Estimating genetic gains from alternative breeding strategies for clonal forestry
Canadian Journal of Forest Research, 1992Concepts and procedures are presented for the analysis of progeny trials that incorporate clonal replication as a means to resolve variance arising from nonadditive gene effects. Components of variance from the linear model may be expressed in terms of expected covariances among relatives, and these, in turn, may be used to derive approximations of ...

Strategies for Clonal Forestry with Norway Spruce
1993Norway spruce [Picea abies (L.) Karst.] is the most extensively used forest-tree species in Europe. Recently, increased interest in its use in northeastern USA and eastern Canada has been expressed; in some areas of this region, its growth and other qualities exceed the indigenous species (Fowler 1979).

Conifer Somatic Embryogenesis and Clonal Forestry
1993Somatic embryogenesis, the formation and development of embryos from somatic (vegetative) tissues under in vitro conditions, was first demonstrated with carrot (Steward et al. 1958). The list of plants that can be regenerated by somatic embryogenesis continues to grow (Tisserat et al. 1979; Ammirato 1983; see references in this chapter).

International Forestry Review, 2009
SUMMARY Forest management activities are designed not only to meet the growing economic and commodity production needs of the human population, but also to maintain, conserve, and protect ecological and social values. This paper presents a set of broad implications of advances in tree cloning technology on forest management and planning, and how these ...

Clonal Forestry with Sugi (Cryptomeria japonica)
1993Since ancient times, sugi (Cryptomeria japonica D. Don) has been one of the most important conifer species in Japan. In the People’s Republic of China, descriptions of Cryptomeria foriunei Hooibrenk ex Otto et Dietr, are also found, however, it is not so popular in Chinese forestry (cf. Hashimoto 1983). In Taiwan, in 1896, the seeds of C. japonica were

Policies, Regulations, and Laws Affecting Clonal Forestry
1993The task on regulation of forest reproductive material was initiated around 1925 in Germany and other Central European Countries. By that time the international seed trade was expanding and it was realized that there should be regulation to protect forest regeneration from unsuitable seed sources.

Cryopreservation of Embryogenic Cultures of Conifers and Its Application to Clonal Forestry
1999Cryopreservation, by providing physico-chemical stability of germplasm, offers the potential for economically and reliably providing long-term storage of genetic resources (Blakesley et al. 1996). It has become a cornerstone of conifer somatic embryogenesis (Adams et al. 1994; Gupta et al. 1994, Smith et al. 1994, Handley et al.
