Abstract
A field experiment was carried out at agricultural field in al-Alam the coordinates of (N 43.835672 - E 34.777260) district/Salahuddin Governorate during (2021 - 2022) A.D season to study, with the aim of evaluating the genotypes and positions in a crop using factorial mating and in these eight flax genotypes were used in this study it is (Sakha 1, Sakha 2, Sakha 3, Sakha 5, Sakha 6, Giza 8, Syrian local and Thorshansity72). and the first parents (males) and the remaining three (females) were chosen to obtain (15) hybrids If the selection was made on the basis of the genetic base of the genotypes, planted randomly and at different dates in the field, and the experiment was applied using a RCBD and with three replications, results and statistical analysis showed the superior genotype (Sakha1) for the traits of the number of capsules per plant (65.66) and the number of seeds in the capsule (9.79) seed capsulesˉ¹ and the yield of the individual plant (2.69) gm plantˉ¹ and the total yield (539.37) kg h-1 and superior hybrid (Sakha1×Syrian local), which significantly outperformed the traits of the number of capsules per plant (67.03) plant capsuleˉ¹, the number of seeds in the capsule (9.77) seed capsuleˉ¹ and the individual plant yield (2.64) g plantˉ¹ and the total yield (529.12) kg h-1. The best parents in the effects of general ability is Genotype (Sakha1) for the traits of the number of vegetative branches, number of capsules per plant, number of seeds per capsule, and the superiority of the hybrid (Sakha1 × Syrian local) in the number of capsules per plant, number of seeds in the capsule, number of seeds per capsule, single plant yield and total and hybrid. Thus, it can be recommended to plant the varieties (Sakha1) (Sakha2) and (Sakha5) because their performance is distinguished in most of the traits under study.
