ABSTRACT Cotton leaf curl virus (CLCuV) and heat stress are the major threats to cotton productivity in Pakistan. Both these factors inflicted huge losses in recent years. Thirty one genotypes of Gossypium hirsutum L. were sown in the experimental area of Cotton Research Institute, Faisalabad, Pakistan, on 25th of May for the purpose of screening against aforementioned stresses. Analysis of variance revealed significant variation among the tested genotypes. Some of the genotypes showed promising results in terms of CLCuV and also showed fair stability of their membranes. The strain FH- 142 showed excellent tolerance level against CLCuV and heat stress by showing the values of 0.4% for cotton leaf curl virus and membrane stability of 46.1%. The other genotypes that showed promising results in terms of CLCuV % are FH-330, MNH-886, MNH-814 and FH-312 and regarding heat stress MNH-456, FH-142, FH-118, CRSM- 38 and NIAB-112 exhibited promising results by showing the CMT % of 46.4%, 46.1, 45.5, 45.5, 44.1, and 41.9%, respectively. The findings of the experiment may be helpful in designing breeding programmes regarding CLCuV and heat tolerance as material had considerable potential for better yield as well.

Cotton Leaf Curl Disease (CLCuD) is one of the threatening constrains of cotton production in Pakistan for which no adequate remedy is available until now. Local variety of Gossypium hirsutum (FH-142) was grown in field and infected naturally by CLCuV under variable range of temperature and humidity. Plants showed thickening of veins in lower leaf surface at 34?C and 60% relative humidity at 15days post infection (dpi) and curling of leaf margins at 33?C with 58% relative humidity at 30dpi. Remarkable leaf darkening was observed with reduced boll formation at 45dpi at 26?C and 41% relative humidity. Enation developed, severe thickening and curling of leaves intensified and plants showed dwarf growth at 60dpi at 24?C with 52% relative humidity. PCR amplification of Rep associated gene confirmed the presence of CLCuD-associated begomovirus in the infected samples. Quantitative RT-PCR confirmed the amplification and differential expression of a number of pathogen stress responsive genes at different levels of temperature and humidity. This observation predicts that Cotton Leaf Curl Virus (CLCuV) interacts with several host genes that are upregulated to make plants susceptible or suppress other genes to overcome host defense responses.
