The strains of BT bacterium produce approximately 200 different toxins known as BT-Toxins which are harmful for different insects most commonly against cotton bollworms(lepidopteran), butterflies, flies, and moths. So, scientist inserted the gene of Bacillus thuringiensis which was harmful for lepidopteran into the cotton crop so that gene produce toxin against lepidopteran and kill the pest and make the cotton crop resistant. we can get the good yield of cotton by using the simple concept of rational plant population which means that we will get the same quantity of cotton as much as we sow the seeds in the earth which can achieved by using the healthy seeds only. Bukhara-8 Variety shows higher resistance towards a salinity soil as compared to C-4727 and Omad varieties as well. cotton show 94% reduction in the feline covid (which is a common cat’s viral infection) upon the 2 hours contact with PHMB. that tetraploid (having four sets of homologous chromosomes) cotton has highest fiber quality as compared to other cotton varieties. we can’t forget the role of biotechnology in the evolution of cotton because it’s the biotechnology which give us BT-cotton or also known as Genetically Modified Cotton or GM cotton.
