Abstract

Most almond cultivars in Iran are self-incompatible. In 2008-2009, a study was carried out to determine the level of self-compatibility of 54 almond cultivars grown in collection garden of Agricultural and Natural Resources Research Center of Fars in Zarghan, Iran, as well as the most suitable pollinizers of six selected cultivars. To determine the level of self-compatibility for each cultivar, four branches were selected and at least 100 buds on each branch were covered, and self-pollinated. The fruit set percentage was recorded 30 and 60 days after pollination. To determine the suitable pollinizers, the six selected cultivars were crossed in a di-allele method. Regarding self compatibility, 41% fruit set formation was observed in Tuono in two years. No fruit set formation was observed in self pollination of other cultivars. Furthermore, cultivars Merced, Tuono and Cristomorto were determined as the most suitable pollinizers for Kapareil, cultivar Tuono for Cristomorto, cultivars Kapareil, Tuono and Merced for Tuono, cultivars Ai and Kapareil for Ferragnes, cultivars Cristomorto and Tuono for Merced and cultivars Tuono and Cristomor for Ai .
