Abstract
Six flax genotypes (five fiber flax cultivars and one dual purpose) were evaluated concerning yield, yield components, technological traits, genetic parameters, phenotypic correlation, anatomical studies and improving fiber characters of Giza 11 (dual purpose) cultivar by increasing seeding rates. The experiments were conducted at Giza Agric. Res. Station, during 2017/2018 and 2018/2019 seasons as a primary trial to study the effect of seeding rates (60, 70 and 80 kg/fed) on yield and its components of Giza 11 cultivar and 2019/2020 and 2020/2021 seasons as a main trial to evaluate six flax cultivars, including local and imported ones. Results revealed that, maximum straw, fiber yields per fed, fiber area and fiber index of Giza 11 cultivar were obtained when seeding rate was applied at the rate of 80 kg/fed. Marlin and Sakha 3 recorded the highest estimates in plant height, technical length, fiber yield/fed. and fiber percentage. Meanwhile, Giza 11 ranked first in seed yield, related characters and xylem area. The environmental variance promote low estimate for most traits, except technical length, plant height, and fiber length. Correlation analysis indicated that, the traits like plant height, technical stem length, straw yield/plant, and fiber length had a strong positive significant relationship with flax cultivars in yield and its components. Whereas, number of capsules per plant, number of seeds per capsule would also be kept in mind while designing a breeding program to improve the seed yield. Regarding stem anatomical characters, Sakha 3 recorded a maximum value for total cross-sectional area and cortex area, while Marlin achieved the highest value of fiber area and fiber index characters.
