Effect of Cotton Leaf Curl Virus Disease on Morphology, Yield and Fibre Characteristics of Susceptible Lines/cultivars of Cotton (Gossypium hirsutum L.)

Ghayour Ahmad, Saeed Ahmad Malik, Zahid Mamood, Muhammad Zaffar Iqbal, Saghir Ahmad and Saeed Ahmad

Abstract

Three local as well as exotic leaf curl virus susceptible lines/cultivars of cotton, i.e., S-12, Acala-1517-C and CIM-70 were evaluated for yield, yield components and fibre traits. This disease had adverse effect on morphological, yield and yield components and fibre quality of all varieties. The cv. CIM-70 exhibited the highest reduction (87.3 %) in seed cotton yield and staple length (7.1 %) due to cotton leaf curl virus disease. The extent of adverse effects of this disease was most prominent on ginning out-turn (-18.2 %) and fibre fineness (23.8 %) of S-12.
