Value of Cultivation and Use (VCU) trial of some new cotton genotypes and cultivars have been performed at Tehran province agriculture and natural resources research and education center at Varamin, based on complete randomized design by four replications during 2016 and 2017. Evaluated cotton genotypes and cultivars include 1) Varamin (control), 2) Khordad (control), 3) Ulran (commercial cultivar), 4) 43259 genotype, 5) A-SJ2×349 genotype, 6) R7 genotype, 7) no. 210 genotype, 8) no. 221 genotype, 9) Leon (foreign commercial cultivar), and 10) Sajedi (new cultivar). Results reveal that Sajedi new cultivar is the earliest cultivar in both years in comparison with other studied genotypes and cultivars. It also has had the most boll number and weight and its seed cotton yield has been in the same statistical group of the highest seed cotton yield control cultivars. The highest lint percentage and fiber elasticity in first year belongs to this cultivar. Therefore, Sajedi new cultivar can be introduced and commercialized for cultivation in Tehran province as well as similar Vatamin regions.
