Influence of Cotton Leaf Curl Virus (CLCV) Disease on Yield and Economic Traits of Cotton

Abstract

Six cotton varieties were evaluated at the environmental condition of Sakrand to assess the CLCV disease incidence % and due to its effect reduction in yield and fiber traits. It was confirmed from the present research that cotton leaf curl virus (CLCV) disease incidence generally has adverse effects on cotton crop growth and development, seed cotton yield, and economic traits. The range of disease incidence % was noted from 19.5% (IUB-13) to 56.8% (CIM-602). Due to CLCV disease incidence up to 50% reduction was noted in plant height, bolls plant-1, boll weight, and seed cotton yield. However, fiber quality traits are less decreased as compared yield traits. Therefore, it is always necessary to recommend cotton leaf curl virus disease resistant/tolerant varieties for general cultivation to combat CLCV and also emphasize on proper control of whitefly, as it is a vector for transmitting CLCV disease from one plant to another. There present study was conducted to document Cotton Leaf Curl Virus (CLCV) disease on yield and economic traits of cotton.
