Abstract: The photosynthetic characteristics and yield & fibre quality was studied under field condition with five hybrid cotton varieties. The results showed that Yu-Za 35 indicated higher photosynthetic rate(Pn) and smaller diurnal change of Pn, Fv/Fm, ФPSⅡ in leaves , consequently having higher ability of utilize powerful light and the highest yield was harvested compared with other varieties. The yield of Zhong mian 29,Biao za A2 and Jing za 2 was higher significantly compared with Biao za A1. The yield of Biao za A1 was lowest because of senescence-early and lower Pn of leaves.
