This study was conducted to evaluate the hybrids obtained from reciprocal crosses of two important commercial almond cultivars including “Mamaee” and “Marcona” in order to identify offspring with superior phenotypic and genetic characteristics during 2019-2022. The fruits of six selected hybrids obtained from reciprocal crosses of “Mamaee” and “Marcona” cultivars with their parents were stored at normal temperature of 24 ° C at harvest, six months and one year after harvest and some kernel traits were measured. The obtained data were analyzed in a two-factor factorial design including cultivar and storage time based on a completely randomized design (CRD) with three replications. The results of variance analysis showed that the interaction of cultivar and storage time of studied traits of kernel including fresh and dry weight, moisture content, ash and protein was significant. The results of comparing the mean interactions of the data showed that the highest amount of fresh kernel weight in MMar13-29 progeny with 1.92 g and the highest dry kernel weight in “Marcona” parent with 1.45 g and MMar13-29 progeny with 1.30 g was observed at harvest time. The maximum protein content was obtained in the “Mamaee” parent and MMar13-01 progeny with 25.11 and 24.25 at harvest time. In all studied traits, a decreasing trend was observed during the storage period and the lowest amount of traits was observed in all selected offspring at one year after harvest, but there was a significant difference between the selected offspring in terms of evaluated traits. It seems that some of the selected high-quality offspring such as MMar13-29 in the present study can be used in almond breeding programs and introduced as superior cultivars by further investigating the stability of traits.
