Abstract :
In order to evaluation of two new foreign (Greek) upland cotton cultivars Value of Cultivation and Use(VCU) evaluation, during 2018 a trial was conducted as complete randomized blocks design by four replications at three provinces, South Khorasan (Birjand), Fars (Darab), and Ardabil (Moghan). Control common improved commercial upland cotton cultivars were: Varamin and Khordad cultivars (South Khorasan province), Bakhtegan and Golestan cultivars (Fars province) and Varamin and Mehr cultivars (Ardabil province). Based on National Guideline for Testing Value for Cultivation and Use of Cotton, evaluated traits were: 1-seed cotton yield, 2- earliness, 3- boll number per plant, 4- boll weight, 5-lint percent, 6- fibers length, 7-fibers fitness, 8- fibers elasticity, 9-fibers strength and 10- fibers uniformity. Based on trials results, in south Khorasan province (Birjand) new Greek cultivars Maxa and Leon respectively in terms of earliness and fibers uniformity were superior to control cultivars. In Fars province (Darab), control cultivars more early maturity than Maxa and Leon new foreign cultivars. Also, Maxa and Leon new cultivars superior than control cultivars in terms of boll number and Maxa new foreign cultivar regarding to fiber uniformity and elasticity superior than control cultivars. Based on the research results, in Ardabil province (Moghan) Leon new foreign cultivar for seed cotton yield, earliness index and boll weight and Maxa new foreign cultivar in terms of boll number were superior to control cultivars. Also Varamin control cultivar and Leon new foreign cultivars regarding to fibers length were superior to other evaluated cultivars. Therefore, Leon new cotton foreign cultivar cultivation as a new cultivar recommendable in Ardabil province (Moghan).
