Estimates of genetic parameters and genetic gains for growth traits of two Eucalyptus urophylla populations in Zululand, South Africa

Van den Berg, Gert J.; Verryn, Steve D.; Chirwa, Paxie W.; Van Deventer, Francois Johannes (Taylor and Francis, 2016-08)

In South Africa, Eucalyptus urophylla is an important species due to its disease tolerance to fungal diseases like Crysoporthe austroafricana and the Coniothyrium sp. cankers. It is mainly planted as a parental species in ...
Genetic parameters and genotype by environment interaction of Eucalyptus grandis populations used in intraspecific hybrid production in South Africa

Van den Berg, Gert J.; Verryn, Steve D.; Chirwa, Paxie W. (Taylor and Francis, 2017)

In South Africa, Eucalyptus grandis is an important species due to its fast growth and general suitability of its timber for a range of products. However, E. grandis is susceptible to fungal diseases such as Crysoporthe ...
Genetic parameters of interspecific hybrids of Eucalyptus grandis and E.urophylla seedings and cuttings

Van den Berg, Gert J.; Verryn, Steve D.; Chirwa, Paxie W.; Van Deventer, Francois Johannes (JD Sauerlaender's Verlag, 2015-01)

The current E. grandis x E. urophylla hybrid breeding strategy of South Africa’s Forestry Industry is to maintain large breeding populations of both parental species in which parents are selected based on their general ...
Realised genetic gains and estimated genetic parameters of two Eucalyptus grandis × E. urophylla hybrid breeding strategies

Van den Berg, Gert J.; Verryn, Steve D.; Chirwa, Paxie W.; Van Deventer, Francois Johannes (Taylor and Francis, 2017-01)

Conventionally, Eucalyptus grandis x E. urophylla (GU) hybrid material has first been tested as seedlings in progeny trials for at least four years before ortets were selected and ramets of the selected ortets were propagated ...
