The evaluation of morphological characteristics correlation in different cultivars of two tetraploid cotton species

To evaluate the distinctive morphological characteristics of cotton cultivars, and the correlation among different traits of cotton species, current research was conducted on Sahel, Golestan, Sepid, M-13, SKT-133, Latif, Termez 14, Barbadense and Doctor Omumi cotton cultivars from 2 different species of Gossypium hirsutum and G. barbadense in randomized complete block design (RCBD) during 2015 year in Hashemabad Cotton Research Station, Gorgan, Iran. Studied traits were included of plant height, number and length of sympodia and monopodia branches, the nodes numbers, bolls number and weight, seed weight, yield and lint percentage. According to the results, for all of the studied traits, significant statistical difference (p
