Identification of Almond Cultivars by Pollen Isoenzymes

Abstract

Horizontal starch gel electrophoresis was applied to the study of almond identification [Prunus amygdalus Batsch, syn. P. dulcis (Mill.) D.A. Webb] using pollen from 44 cultivars of different origin. Variability was found in all of the nine enzymatic systems analyzed (PGM, AAT, GPI, LAP, 6PGD, AcP, CAT, IDH, and ADH). The enzymatic systems with the highest discriminating possibilities were PGM, CAT, AcP, and LAP. This variability enabled the 44 cultivars to be distinguished with the exception of two pairs.

“…The number of SCoT-PCR specific markers, (22) was scored in Prunus armeniaca, (13) was recorded in P. dulcis var. amara, (12) was recorded in P. persica, (11) was scored in P.…”

“…Molecular studies for the identification of genotypes like RFLPs or RAPDs are very recent in fruit trees [19]. Isoenzyme markers in Prunus trees like peach [29,31], almond [5,13] and cherry [10,34] were developed. Also additional markers, such as SSRs have recently been developed for peach [15] and apricot [17].…”
