Study of Compatibility Relationships Among Some Almond Cultivars and Genotypes Using of SAlleles Identification
Authors
Abstract:
Almond (Prunus dulcis L.) is one of the most important nut crops in Iran. Most almond cultivars and genotypes are self-incompatible. However, research on S-alleles indicates that it is very efficient in cultivar selection. Selfincompatibility in almond is gametophytic and controlled by a single S-locus with multiple codominant alleles. In this study, compatibility relationships among cultivars, “Tuono”, “Shokofeh”, “Sahand” and five improved genotypes “A1.16”, “A9.7”, “A8.39”,“A10.11” and “A230,” was investigated by the PCR of S-alleles. Degenerate primers (PaConsI-F, EMPC1consRD, EM-PC2consFD, and EM-PC3consRD) were used for amplification of S-alleles. Results showed that only “A10.11” and “A8.39” were completely cross-incompatible, but all of the other studied cultivars and genotypes were crosscompatible. Furthermore, cultivar “Tuono” and genotype “A1.16” had a self-fertility allele.

study of pollen compatibility relationships among some selected promising almond cultivars and genotypes
almond is one of the most important prunus species. most almond cultivars and genotypes are self-incompatible and some others are cross-incompatible. however, recently self-incompatible cultivars developed by breeding are available. therefore self-incompatible cultivars for pollination, fertilization and production require compatible pollen of other cultivars. in this regard the study of pollen...

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...
