| Abstract:
Almond occupies a peculiar place among fruit and nut trees. Almond genetics has been studied less than other Prunus species, but is better understood than the genetics of other nut trees. Only five qualitative traits have been identified in almond, and two more are also probably qualitative. Heritabilities have been estimated for a large number of quantitative traits, mainly phenologiy and fruit characteristics. At present, an increasing amount of information is available on molecular markers, including enzymes, RFLPs, RAPDs, and others. Linkages, however, have only been established among molecular markers, allowing the creation of accurate genetic maps, but not the location of agronomical characters in these maps. Thus, a greater effort has to be directed to the study of the genetics of agronomical traits. The effective application of genetic maps in plant breeding will depend on accurate study of the expression of these traits. Field work will be required, as grower profits depend on cultivars with beneficial traits expressed under field conditions. | |
