The comparion on seed and oil yields, oil quantity and quality of Flaxseed (Linum usitatissimum L.) cultivars and accessions

In order to evaluate quantitative and qualitative yield of some flax cultivars and accessions(Linum usitatissimum L.), an experiment was conducted at research farm of Shahid Chamran University of Ahvaz based on randomized complete block design with 12 treatments and 3 replications. Treatments were six cultivars (Golda, Oliozon, RH2, Lirina, Livia and Uanda) and six accessions (Ardebil1, Ardebil2, Ardebil3, Ardebil4, Karaj and Hamedan). The measured traits were plant height, branch number, leaf area, capsul number, seed number per capsul, seed yield, oil content and composition. There were significant differences between cultivars and accessions for all measured traits. Ardebil4 and Ardebil3 had the highest capsul number and the minimum value was recorded in Golda and Livia. The highest and the lowest seed yield were observed in Ardebil4 and Livia, respectively. The highest oil percent was recorded in Hamedan, Ardebil4 and Ardebil3 while the lowest amount was obtained in Golda. Lirina and RH2 had the highest and the lowest amounts of alpha-linolenic acid, respectively. The highest and the lowest amount of linoleic acid were recorded in RH2 and Karaj, respectively.Overall, Ardebil3 and Ardebil4 with higher seed yields, oil percentage and rich source of alpha-linolenic acid may be the best accessionsfor cultivation in Ahwaz conditions. However, more investigation is needed.
