Abstract

Walnut is one of the native fruits of Iran which due to its propagation with seeds has great genetic diversity in Iran. Although the quantitative and qualitative characteristics of walnut fruit have been studied in different parts of Iran, there is no report on the genetic variation of walnut in Khuzestan province. In the present study, some quantitative characteristics of fruit and profile of fatty acids in 14 genotypes of Izeh (Sheivand, Haji Kamal and Sadat Husseini regions) were investigated. Results showed that fruit dimensions, fruit shape indices, fruit weight and kernel percentage were significantly different in walnut genotypes. Analysis of walnut oil fatty acids in 14 genotypes showed that Sheivand-1 had the highest amount of linoleic acid (60.88%). Sadat Husseini-A had the highest oleic acid (35.76%). The highest amount of saturated fatty acids (SFA) was in Haji Kamal- D, Monounsaturated fatty acids (MUFA) in Sadat Husseini-A and polyunsaturated fatty acids (PUFA) in Sheivand-1 (11.87, 36, 72.59, respectively). The results showed genetic variation of walnut stands in Izeh region. It is suggested that further studies be carried out on the genetic variation of walnut in Khuzestan province and the possibility of expanding walnut cultivation in southwestern Iran.
