Fars provinceis one of the most important region for almond production.More than 22% of the whole almond production and 19% of almond cultivated area is located in Fars.Many local and wild cultivars have been detected by foreign and Iranian researchers.Almond collection has been studied,Identificated and high yield cultivars introduced to the orchard growers. In present study 54 foreign and local almond cultivars have been grown 10 years.This study was based on balanced group blocks design.There were cultivars each 6 groups.4 tree were planted in each plot and the grand total was 648 yield kg/tree ,the percentage of kernel and blooming time were the most important properties wich staticaly analyzed in 2001.Analysis of variance showed that there was significant difference(1%) inter and intra groups. Three years mean yield comparsion revealed in group 1(very hard shell) cultivars 7 and 8, in group 2(thick shel) cultivars 2,26,29, in group 3(half-thick shell) cultivars 1,24 in group 4(fairy thick shell) cultivars 9,12 in group 5(fairy paper shell) varieties 6,21 and in group 6(paper shell) cultivars 10,13,14,15,16,36 had significant difference(1%) with others.From kernel aspects cultivars No:21(3.62 kg/tree) No:7(4.4 kg/tree) No:3(3.56 kg/tree) and No:21(3.62 kg/tree) had the best yield respectively.cultivars No 7,8 with 14.9 and 12.38 kg/tree had the best nut yields. From view of the kernel perecentage there were wild range(from 20 percentage up to 70 percentage) there were significant correlation between blooming,although there were another effective characterictics in yield.Fotunately,the late blooming cultivars had high yield. .
