| ABSTRACT. Fifteen genotypes of flax (Linum usitatissimum L.) were evaluated during the two consecutive seasons 2020/2021 and 2021/2022 at the Gemmeiza Agricultural Research Station, Agricultural Research Center, El-Gharbia Governorate, Egypt. Three replications of a randomized complete block design were used. The performance of Giza 11 and Giza 12 was outperformed compared to other genotypes for most studied traits in both seasons. For both the phenotypic and genotypic coefficients of variability, most studied traits under investigation showed close values. High heritability in the broad sense coupled with high genetic advance (as % of mean) for most studied traits was observed. The best selection criteria for improving straw yield/fed were plant height and technical length. To improve seed yield/fed. However, number of capsules per plant and seed index (1000 – seed weigh) was useful selection criteria. | ||
