Abstract:
Leaf Curl Virus disease is one of the major impediments constituting a primary limit on the productivity of cotton particularly in Punjab province. This menace has brought about a huge loss of about Rs. 9 billion to the economy of Pakistan during the last fifteen years. Since the resurgence of new strain of cotton Leaf Curl Virus (Burewala Cotton Leaf Curl Virus) in 2001, ten thousands lines (local as well as exotic) of Gossypium (upland cotton) have been screened during the last five years (2003-2007) at Cotton Research Station, Vehari (Cotton Research Institute, Ayub Agri. Institute, Faisalabad) but no resistant material have been identified.
Gossypium arboreum (desi cotton) occupying 5% of the total area under cotton in Pakistan has been found resistant to Cotton leaf Curl Virus disease since the appearance of this disease in Multan (Pakistan) during 1967. Therefore introgression of CLCV resistance genes from Gossypium arboreum and other wild species into cultivated upland cotton (Gossypium hirsutum) is of vital importance in solving this hazardous problem. Moreover Gossypium tomentosum will also be used to transfer CLCV resistance into upland cotton. However main focus will be on G. arboreum.
