ABSTRACT
Cotton (Gossypium hirsutum) is one of the largest source of natural fiber that’s why its
production is required in enormous quantity, but different environmental stresses cause the lost
in the yield. Genetic engineering has enabled us with various techniques to overcome the losses
and fulfilling the human needs through modifying the genetics of plant cells. In this study a
variety of cotton plant was modified using Agrobacterium tumefaciens with BAR gene. BAR
gene was inserted to resist the effect of herbicide bialaphos, which affects the primary growth of
plants. The whole study was conducted at Four Brothers genetics. The Bar gene cassette, seeds
and all the necessary material was obtained from Four Brother genetics. The construct was
already made and it was just transformed to A. tumefaciens. The seed were delinted, soaked and
BAR (Bialaphos resistant gene) was transformed to germinated embryos. After the step by step
growth of embryos into healthy plants, molecular analysis for transformation of BAR gene was
confirmed through leaf sample of stable transformed plants. Transformation was determined by
PCR and gel electrophoresis. The entire study confirms that transgenic cotton variety of eagle-2
shows better results of transformation for BAR gene than other varieties.
