Abstract

Almond is one of the most important nut crops of Maragheh, Iran. In the present study, six Maragheh indigenous genotypes with favorable traits were selected for the investigations of pollen tube growth, fruit set and their compatibility. Genotypes were pollinated by the pollen of each other. Fruit set was studied in the filed, and pollen tube growth was studied in the laboratory with florescence microscopy. Experimental design was completely randomized with different number of treatments (pollen type) and 4 repeats in all of the crosses. Data were analyzed with SAS software. Results showed that, all of the genotypes were cross compatible, although the pollen tube number in the ovary was affected by the pollen type but fruit set was not affected.

Key words: Almond, cross-compatibility, pollen tube growth, florescence microscopy, fruit set.
