Abstract :
Almond is one of the most important Prunus species. Most almond cultivars and genotypes are self-incompatible and some of others are cross-incompatible. Therefore self-incompatible cultivars for pollination inoculated and production require compatible pollen other cultivars. In this regard the study of pollen and pistil compatibility of the three cultivars Tuono, Shokofeh, Sahand and promising three genotypes choice A1.16, A9.7, and A230 using method controlled pollination and pollen tube growth by fluorescence microscopy in laboratory and determine the fruit set percentage in the field. Crosses were performed based on flowering overlap among the five groups For Diallel crosses was performed. Results showed that crosses♀ Tuono × ♂A9.7 (60.52 fruit set and 10.97 pollen tube penetrate in the ovary), ♀A9.7 × ♂Tuono (66.67 fruit set and 10.4 pollen tube penetrate in the ovary) and ♀ Shokofeh ×♂ A1.16 (74.92 fruit set and 14.40 pollen tube penetrate in the ovary) the highest of compatibility on dialle crosses were used in mentioned groups. Furthermore crosses♀ A230 × ♂ Tuono (30.9 fruit set and 3 pollen tube penetrate in the ovary) and ♀ Sahand × ♂ Tuono (29.2 fruit set and 1.8 pollen tube penetrate in the ovary) showed Least of compatibility on dialle crosses.
