Heritability , Genetic advance and correlation of some technological characters in many of cotton


Abstract in English

Seven cotton varieties ( Rakka5, Aleppo133, Aleppo90, Aleppo118 , Aleppo40, Deir22, Line124) were grown in village Salhab ( Al-Ghab region , Hama) in 2012 using randomized complete block design with three replications. were used to study estimation of variance, broad sense heritability, genetic progress and correlation some of their technological characters (Staple length mm, Length uniformity% , Fiber fineness %(micronaire), trength Fiber(g/tex), Fiber elongation%, fiber maturity%), that’s to explore potentials Genotypes in search region and put the numerous selectoral evidence in order to obtain an additive and fast improve on the technological characters, The study showed significant differences between in the studied genotypes, for most of the considered traits. The study suggested a variation of the values of Heritability, Genetic advance in the characteristics technological of cotton., the highest Heritability of which was in the Staple length and than trength Fiber, Fiber elongation , Fiber fineness, fiber maturity, Length uniformity, characteristics where the inheritance degree reached (0.98, 0.97, 0.89, 0.80,0.75, 0.30) , genetic development% (1.03, 1.35, 0.36, 1.31,1.22, 0.11). The results also showed a positive significant correlation between Staple length and trength Fiber (r = 0.901**), also between Fiber elongation with fiber maturity and Length uniformity ( r = 0.64**, r = 0.422**), and this gives us the area and ease of movement to put the numerous selectoral evidence in order to improve the technological characters of cotton.
