Abstract
A two-year study was conducted at Giza Research Station, Agricultural Research Center, Giza, Egypt during 2022/2023 and 2023/2024 seasons to evaluate the yield potential of twelve promising flax lines, identify seed morphological traits, yield components, technological traits and molecular markers comparing to commercial Giza 12 and Sakha 3 as check varieties. Results indicated that differentiation existed between all genotypes under investigation for seed morphological characters. Germination and seedling traits showed significant differences among genotypes. Yield and its components differed significantly among the flax genotypes for all the studied traits. S.3 and S.8 recorded the highest fiber yield per feddan. Meanwhile, S.6 and S.10 recorded the highest values seed yield per plant (g), seed yield per feddan (kg), and oil yield per feddan (kg). A total of 119 SCOT fragments were recorded, with 33 monomorphic and 86 polymorphic amplicons, resulting in 72% polymorphism. The polymorphism heterozygosity index values SCOT marker traits were ranged as H (0.44-–0.7), PIC (0.35–0.642), E (1–2.67) HAV (0.009–0.7), MI (0.025–0.7) and D (0.113–056). The proportion of observed polymorphism was 63%. SCOT-2 and SCOT-36 had the highest number of unique bands (4). There was a similarity between the PCA, heat map, and dendrogram distributions of S.8, S.9, S.3, S.7, Giza12 and Sakha3. All data revealed a significant differences, among the surveyed flax genotypes at the molecular level.
