Genetic Diversity in Apricot

Genetic Mapping of Blooming Time in ‘Marcona’ × ‘Fragness’ Population with Using Molecular Markers

Flowering time is an important horticultural trait in almond since it is essential to avoid the late frosts that affect production in early flowering cultivars. Evaluation of this complex trait is a long process because of the prolonged juvenile period of trees and the influence of environmental conditions affecting gene expression year by year. In this research flowering time was studied in an...

Molecular mapping of genetic and chromomeric units in Drosophila melanogaster.

We have used a set of overlapping cloned segments defining a 315 kb (X 10(3) base-pairs) region of Drosophila melanogaster chromosomal DNA to map the sequences associated with the polytene band-interbands (chromomeric units) and with the lethal complementation groups contained within this region. The molecular map positions of the 13 +/- 1 chromomeric units from the 87D5-6 to 87E5, 6 region of ...

Molecular Characterization of Apricot Germplasm from an Old Stone Collection

Increasing germplasm erosion requires the recovery and conservation of traditional cultivars before they disappear. Here we present a particular case in Spain where a thorough prospection of local fruit tree species was performed in the 1950s with detailed data of the origin of each genotype but, unfortunately, the accessions are no longer conserved in ex situ germplasm collections. However, fo...

SRAP based genetic analysis of some apricot cultivars

Apricot (Prunus armeniaca L.) is an important fruit species in Turkey with high level of economic value. Sequence related amplified polymorphism (SRAP) markers were used for the first time to determine genetic diversity and relationships among Turkish and some foreign apricot cultivars. A total 87 bands were obtained from SRAP analysis and 63 of them (73%) were polymorphic. Similarity values am...
