Assessment of quantitative and qualitative traits of some promising cotton cultivars in varamin region

Cotton belongs to the family Malvacea and genus Gossypium and commercial cultivars in Iran belong to species Hirsutum. Cotton is the most important natural source of fiber currently used in the textile industry. This study was carried out at Varamin research center in order to evaluate the agronomy and fiber quality traits of new developed cotton varieties which are having high performance in term of various traits as compare to current commercial cultivars. The assessment comprising nine cultivars as well as Varamin and Sahel cultivars as checks, performed during 2005-2006 using RCBD with four replications. The results showed that cultivar 43259 had outstanding features in view of yield and earliness. Because of short sympodia and lower plant height, this variety was appeared as a dwarf and compact cultivar as compare to others. These remarkable characters can be used in development of current commercial cultivars or breeding of new varieties and hybrid seed production programs. Two cultivars, namely Avangard and Opal showed highest value of earliness compare to others.
