Abstract：NC Ⅱ Cross design with six cotton varieties as parents were conducted in Shihezi Agricultural Institute in order to estimate genetic variance，variance ratio，heritability and genetic correlation with important economic traits of the chlorophyll fluorescence parameters of cotton leaves. The results showed that dominant variances were most important in Fv/Fm、Fv/Fo and NPQ，but that there were additive variances in qP. The narrow sense heritability of Fv/Fo were also the highest while Fv/Fm and Fv/Fo were significant at 0.01 level in the broad sense heritability.The dominant correlation effects of Fv/Fm to yield traits were negative and significant and that Fv/Fm correlated well with fiber characters. qP、NPQ were correlated negatively with important economic traits.
