SEPARATION AND IDENTIFICATION OF A NUMBER OF UNSATURATED FATTY ACIDS FROM DIFFERENT TYPES OF ALGAE

Seven cotton genotypes were grown in a different environmental conditions (as a ‎combination among plant densities: 15, 20, and 25 cm under salt and non salt stress ‎irrigation) to estimate genetic behavior in different environments of cotton genotypes ‎‎(Ceebro, W888, Pac-cot189, Lashata, Cocker310, Montana, and Ik259).Analysis of variance ‎for the interaction environments with the genotypes according to Randomized Completely ‎Block Design with three replications were used, furthermore GGE biplot analysis for the ‎seed cotton yield. Results Showed: Environments affected high significant in seed cotton ‎yield for studied genotypes. Genotypic and genotypic environmental interaction contribute ‎of 14.7 and 32.2% of variation respectively. PC1 and PC2 interpreted 53.9 and 26.5 % ‎respectively of differences in GGE variances.IK259 Genotype the most productive and ‎stable than others for high PC1 and low absolute value of PC2.E6 environment correlated ‎significant and positive with other environments that means the effect of salt water stress in ‎a wide distance among plants (25cm). Better performance of IK259 genotype was under un ‎salt stress conditions in narrow distances among plants(15 cm). While Pac-cot genotype was ‎favorable in most salt stress conditions. Consequently IK259 and Pac-cot189 genotypes are ‎productive and desirable in studied environments.‎

Keywords: Cotton Genotypes, Environments, GGE Bi-Plot Analysis.
