To determine the effect of male donor on fruit size and certain tasting characteristics of almond kernel among a population of almond seedlings in Maragheh region an investigation was carried out during the years 1996 and 1997. Four genotypes of naturally large, medium and small size with bitter taste fruits were identified and the effects of pollen grain on fruit size and certain tasting characteristics of kernel studied. Flowers were cross-pollinated at least two times during effective stages of pollination, trees being kept away from bees and other pollinating insects. The resulted fruits from open and cross pollination were harvested, the traits such as fruit length, width, thickness, weight, endocarp thickness, kernel length, width, thickness and shelling percentage being measured. Data obtained from a completely randomized design were analyzed and compared with Duncan’s multiple test range, which showed to be significant at 1% level. The results from these crossings showed that although the female parent effects were prominent but the male parent effects on quantitative characteristics were found to be significantly varied. However, no direct effect from female parents on kernel taste, bitterness or sweetness, was noticed.
