Pistacia atlantica is the most important tree species for the economy of many rural areas in west of Iran, but no effort has been made for the genetic improvement of this species. The aim of this investigation was to study the genetic variation and inheritance of early growth traits in P. atlantica. For this purpose, three wild pistachio populations comprising 60 randomly selected adult trees f...
When fitness returns are sex-specific, selection should favor the facultative adjustment of offspring sex ratios. Seasonal shifts in offspring sex ratios are predicted to be particularly beneficial in short-lived, sexually dimorphic species in which hatching date is linked to adult size, which is related to fitness in a sex-specific fashion. We used four time series of hatching dates and progen...
The maintenance of the endangered Caspian brown trout Salmo trutta caspius populations in Iran depends on its artificial breeding. There is no information on how current hatchery breeding protocol influences effective population size of breeders (Ne), which is a critical parameter to maintain genetic diversity in future generations. The current hatchery protocol (CHP) was comparatively evaluate...
In Chile, interspecific hybrids between Eucalyptus nitens × globulus (GloNi) were developed by Arauco Forestry to capture specific traits from each parental species: growth rate and cold resistance E. (NIT) wood properties (GLO). Field tests of distributed in two geographic zones: (12 tests) Valdivia (15 tests), where measurements recorded at different ages. The hybrid population is composed cl...
Pig chromosome 7 (SSC 7) has been shown to be rich in QTL affecting performance and quality traits. Most studies mapped the QTL close to the swine leukocyte antigens (SLA), which has a large effect on adaptability and natural selection. Previous comparative mapping studies suggested that the 15-cM region limited by markers LRA1 (mapped at 55 cM) and S0102 (mapped at 70 cM) contains hundreds of ...
