Abstract:

Seed orchards are an important source of seeds with improved genetic quality. Here we present results of a study on the genetic composition of seed orchards crop of Austrian black pine (Pinus nigra Arn.). Two seed orchards were included in the study &ndash; a clonal seed orchard established near Sliven, and a seedling seed orchard, established in the region of Simitli. The outcrossing rates were higher in the clonal seed orchard (Sliven), 0.873 and 0.806 multi-locus (tm) and single-locus (ts) estimates, respectively. The same values were 0.623 and 0.530, respectively, in the seedling seed

Abstract:

Abstract The seed orchards (SO) serve possibilities to collect seeds from the selected genotypes or to create artificial population throughout the controlled crossing of the target genotypes. Therefore, the seed material obtained from the clonal and seedling seed orchards offers unique opportunity to improve the genetic value of seeds. Thus, the seed orchards are considered as an important part of the forest seed base being the key object for both modern forestry and forestry research. This paper outlines the forest breeding activities associated with the seed production in the seed orchards i

Abstract:

The annual demand and supply of genetically improved planting stock suitable for sites across varying landscapes, with changing climatic conditions and increasing pest and disease threats are becoming more complex. The agility for effective responses to long-term sustainability of commercial plantations, aimed at different markets, requires a significant investment in genetic resource acquisitions, tree breeding, land management, gene conservation and plant production systems. Tree breeding is one of our most important adaptation strategies in response to climate change and related challenges.

Abstract:

 The optimum design of seedling seed orchards in order to maximize genetic gain was investigated. Variance components were estimated on the basis of heigts of individual plants in the first-generation seed orchards of Encaliptus pelita with ages of 1 to 5 years old. The seed orchards were established at two locations in Indonesia - South Kalimantan and South Sumatra. There were three types of variance components,comprising family variance ,plot error variance, and within plot variance was derived using family variance as a percentage. A linear regression equation within plot variance was

Abstract:

The reproductive biology of western white pine ( Pinus monticola Dougl. ex D. Don) at the Saanich seed orchard (SSO; a coastal seedling seed orchard) and the Kalamalka seed orchard (KSO; an interior clonal seed orchard) is described. Seed-cone development and morphology determine seed potential and affect filled seed production. Seed potential was high, commonly over 200 seeds per cone and filled seeds per cone averaged 50–60 at both orchards in 1999 from open pollinations combined with operational supplemental mass pollinations (OP-SMP). Filled seeds per cone at SSO in 2004 averaged 115 with

Abstract:

A genetic improvement project for black spruce (Piceamariana (Mill.) B.S.P.) was initiated in Minnesota in 1974, with an objective of improving the inherent growth rate of the local population. This study reports some field results from the initial phase of the project. Study objectives were to (i) estimate genetic and environmental variance components of early (age 10 years) tree height, (ii) estimate expected genetic gains from various selection methods in three seedling seed orchards and a clonal seed orchard, and (iii) evaluate the effect that these selection methods have on inbreeding lev

Abstract:

Abstract The end product of any breeding program is the material to be used in propagating plants for afforestation or reforestation programs. Before the recent progress with mass vegetative propagation, all new eucalypt plantations originated from seed. Although vegetative propagation will decrease the demand for seed, we consider that seed will still play a major role in plantation establishment for many years. Somespecies are very difficult to propagate vegetatively and even for more favourable species many problems are still being experienced with rooted cuttings. This chapter deals with m

Abstract Forest landscape restoration is a participatory process for setting objectives that should be explicitly stated and recognize the needs of local communities. Restoration technology should be appropriate to site and landscape conditions as well as socioeconomic and cultural contexts. This chapter focuses on establishing forests where they are currently lacking. The techniques discussed can also establish trees outside of forests or restore degraded forests. Topics include understanding and documenting initial conditions and monitoring outcomes. Passive regeneration techniques include n

Date palm (Phoenix dactylifera L.) plants demand reclamation of new areas or renewal of the oldest trees. Different methods to produce these plants as seeds that gave only 50% of seedlings will be female. The dates from seedling plants are often smaller and of poorer quality, so the propagation of date palm plantlets will occur with different methods. In vitro culture produced true-to-type huge numbers of plantlets under control conditions that led to many differences in morphology, physiology, and anatomy characteristics. The acclimatization was done to modify these abnormalities, and the pla
