The finding of new self-compatible cultivars in local population is a breeder’s objective in order to increase the sources of self-compatibility for the almond (Prunus amygdalus Batsch) breeding programmes. ‘AS-1’, a local Spanish selection, was considered to be self-compatible according to its self pollen tube growth and was incorporated in the almond breeding programme of Zaragoza as a source...

The evaluation of an almond collection using morphological variables and identification of self-incompatibility genotype  is useful for selecting pollinizers and for the design of crossing in almond breeding programs. In this study, important morphological traits and self-incompatibilities in 71 almond cultivars and genotypes were studied. Simple and multiplex specific PCR analyses were used in...

for a comparison and grouping of 72 almond cultivars and genotypes, 30 traits including; 12 phenological and vegetative characters plus 18 traits related to nut and kernel were assessed, according to almond universal descriptor. the results revealed that some such traits as growth habit, flower color, nut weight, shell hardness and kernel taste carried high coefficients of variation. simple cor...

Simple sequence repeat (SSR markers or microsatellites), based on the specific PCR amplification of DNA sequences, are becoming the markers of choice for molecular characterization of a wide range of plants because of their high polymorphism, abundance, and codominant inheritance. Different methods have been used for the analysis of the SSR amplified fragments being submarine agarose electropho...
