Embodiment Construction

[0024] The contriver has carried out the selection and propagation work of Eucalyptus new variety of the present invention in Guangxi Dongmen Eucalyptus forest field, and process is as follows:

[0025] (1) Female parent: Introduce a batch of 8 Indonesian provenances, afforestation of 30 mu in the rainy season from March to April of that year, establish the experimental E24 Eucalyptus urophylla provenance test, investigate the survival rate and complete the replanting within one week after the afforestation;

[0026] Male parents: A batch of 28 Australian provenances were introduced, and 35 mu of forests were planted in the rainy season from March to April of that year. The experimental E1 tree species and fertilization experiments were established. The survival rate was investigated and replanted within one week after planting.

[0027] Select tree species and their individuals in the established E24 provenance test, select the female parent U16, and select the male parent G33...

Abstract

The invention discloses a breeding method for clonal DH33-27 variety of Eucalyptus urophylla*E.grandis. The method comprises the following steps: firstly, taking Eucalyptus urophylla U16 serving as a female parent and Eucalyptus grandis G33 serving as a male parent as parents; performing emasculation and bagging, pollen collection, hand pollination, cap bag removal, seed collecting and sowing and breeding to realize consistent character expression and stable inheritance. The clonal DH33-27 variety of Eucalyptus urophylla*E.grandis which is not subjected to segregation of character has the variety characteristics that the leaves are lanceolate, terminal buds are green, veins are obvious, seedling stems are slightly red, tree trunks in the early stage is brownish red, the upper parts of the tree trunks are cyan, and the tree trunks are completely peeled in the later period; the clonal DH33-27 variety of Eucalyptus urophylla*E.grandis has the characteristics of high general performance, straight stem shapes, order forest form, small branches, high annual average amount of growing stock and obvious economic benefit, is free of plant diseases and insect pests and suitable for large-scale cultivation promotion.

Description

technical field [0001] The invention relates to the field of plant breeding, in particular to a breeding method for the clone DH33-27 variety of Eucalyptus urophylla. Background technique [0002] At present, there are many eucalyptus species in my country, such as Eucalyptus urophylla, Eucalyptus grandis, Eucalyptus blue, Eucalyptus durnen, Eucalyptus durn, etc., which can produce a variety of industrial woods; China has entered an ecological society, and the sustainable development strategy has become more and more popular in the world. The more countries and the public pay attention to and recognize it, the sustainable development strategy of my country's forestry is also guiding the development of modern forestry in countries around the world. However, due to the influence of eucalyptus species, although many species of eucalyptus in my country have strong growth ability, due to the short felling cycle, Instant eucalyptus has strong regeneration ability. Due to successive ...
