Conventional and Transgenic Cotton Resistance

The present study was conducted to determine the comparative resistance of ten genotypes of conventional and transgenic cotton was studied under field conditions. The results revealed that infestation of spotted bollworm was high on squares, flowers and bolls of FH-207. The infestation of pink bollworm was high on CIM-2015 followed by PKR-101, CIM-554, FH-207 and CRSM-07.The infestation on squares and flowers of CIM-554 was significantly high followed by PKR-101, CRSM-07, CIM-2015 and FH-207. Overall infestation of bollworm complex was found to be high in CIM-554, CIM-2015 and FH-207 as compared to other transgenic and conventional cott0n genotypes. However, BT-05, SITARA-08 and FH-133/14 emerged as comparatively resistant varieties.
