In order to obtain new late flowering almond varieties with desirable pomological and vegetative characteristics, and suitable fruit/kernel characteristics, a program of hybridization between available commercial varieties with possible occurrences of inferior characteristics was started in 1990. In order to reach to the a.m. goals AZAR (AH 50) and Fragnis (Fr) varieties were selected as the maternal varieties and eight other varieties were selected as the pollen donors. In this program about 290 hybrid seeds were obtained from almost 14 different combinations of crosses. The seeds were planted in plastic vases after passing stratification stages. After one year the seedlings were transferred to the hybrid almond orchard and looked after. In 1995, the first flowering bud emergence data was recorded. From 1996, for three consecutive years vegetative characteristics of these hybrids trees in seven different traits were recorded along with twenty-one different traits for fruit/kernel characteristics based on IBPGRI descriptor for almond. Then, based on grading and assigning values with respect to the importance and effectiveness of traits in production, quality, and quantity of fruit/kernel, twenty superior hybrid genotypes were identified by utilizing computer software and entering more than twelve thousand data. After that twelve promising genotypes were reproduced, and are being studied as a research project along with three other genotypes in two different locations.
