Value for cultivation and use of new cotton genotypes on yield, morphological and fiber quality traits

Genotypes 43259, 43347, N-200, Tabladila, Chukrova, B-557, Sepid-2 and Sahel in the form of randomized complete block design (RBCD) in Hashem-Abad Cotton Research Station located in eleven kilometers northwest of the city of Gorgan for a crop year were examined. The experiment in four replications with 20 × 80 cm planting pattern and length eleven meters were planted in four rows. mean Duncan test at level 1% were compared and correlation was found in the above genotypes.The results of variance analysis showed that the genotypes difference on total seed cotton, yield of first picking, the number of monopodia, thirty boll weight, plant height and yield of second picking were significant at 1% and number of sympodia, length of sympodia, length of monopodia and number of bolls is significant at the 5% level. The results of comparison of mean traits showed the N-200,43259, 43347 and B-557 cultivar were superior to other cultivars . In the first picking of seed cotton, results showed that the N-200 and B-557 respectively (2863 and 2725) kg per hectar of seed cotton had the greatest product in first piking. 43259, 43347, Çukurova cultivars have lower height than other varieties.Correlation table showed between first picking of seed cotton and total seed cotton is positive correlation(0.879) and correlation between them was significant at 1%. Between length and number of sympodia was positive correlation and significant at 5%(0.399).
