Spatial Survey of Cotton (Gossypium hirsutum L.) Insect Pests and Leaf Curl Virus (CLCuV) in Relation to Weather Parameters in Muzaffargarh, Punjab, Pakistan

Abstract Cotton productivity is severely hampering by various diseases and insect pests especially cotton leaf curl virus (CLCV) worldwide. Losses caused by CLCV are far more than any other factor affecting cotton productivity. Growing of early and resistant genotypes is of vital significance in alleviating the adversities of these pests in crop plants. The current field trial was conducted at Central Cotton Research Institute (CCRI) Multan, Pakistan, to investigate the role of varying sowing dates in managing the CLCV infestation on different elite cotton genotypes. The crop was sown on five different dates i.e. D1= 15th April, D2 = 1st May, D3 = 15th May, D4 = 1st June and D5 = 15th June and three different elite cotton genotypes, i.e. V1= CIM-612, V2 = CIM-591 and V3 = CIM-573 to optimize a suitable sowing date and to screen out high productive and tolerant genotype against the CLCV. Seeds were drilled manually on finely crafted seedbed by using single row hand drill keeping seeding density of 20 kg ha-1 and inter row spacing of 75cm. CLCV severely hampered the crop performance by delayed planting of cotton from 15th April, while increased the chances of disease incidence. It is concluded that early sowing of all tested genotypes especially CIM-592 reduces the problem of CLCV and enhanced cotton productivity.

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.
