AbstractA field Experiment was Conducted at the farm of Agriculture collee , University Of Anbar, the alternative location (Abu – Gharib) during the season of 2016 to study the effect of planting density (66666, 55555, and 47619) on the yield of the seed cotton and its components for eight cultivars of Upland cotton (CA22, IK347, Lachata, Aleppo 33, Montana, Coker 310, Sp 8886, Iranian 16). Split plot design within R.C.B.D with three replication was used. The varieties as a main plots, while the three siding rates as sub plots with three replication. Genotypic, phenotypic variances and coefficient of variability broad since heritability percentage of fiber index for all planting density (D1, D2 and D3) were high (91.8, 86.9 and 90.5) respectively. Path coefficient analysis that number of bolls and fiber ratios for plant density (D1 and D2) gave highly effect direct (0.92 and 0.94) respectively, while weight of bolls gave high indirect effect from (D3) (0.99).
