- Lucknow: CSIR-National Botanical Research Institute (NBRI), Lucknow, has developed a special chip that will assist scientists and farmers in cultivating superior cotton plants.Upon insertion of this ‘90K SNP Cotton Chip' in special equipment, it will provide data about various cotton varieties and their characteristics. The chip facilitates the development of high-quality cotton plants through marker-assisted breeding (MAB), a DNA-based approach. This utilises molecular markers to identify and choose plants with specific traits, creating new varieties."The chip contains data of around 90,000 cotton SNP markers, which can be used to crossbreed and create a new variety according to climatic, production or pest control needs. This is the first such chip in India, and its license was given to a Delhi-based company in the presence of CSIR director general N Kalaiselvi," said NBRI director Ajit Kumar Shasany.Explaining MAB or chip technology, Shasany said: "In agricultural production, we often aim to combine good traits from different plants to breed a new variety. Suppose we have a cotton plant with many seeds but fewer branches and is not drought or pest-resistant while another variety has fewer seeds but is drought and pest-resistant and has more branches. We can combine these two to breed a desirable variety.""This may sound easy, but it's a herculean task as suitable varieties must be identified from thousands before crossbreeding. It may take months and even years. It's tough to determine which one is the best. The agricultural performance of plants is usually linked to traits that are encoded by DNA," he said.Shasany added that this chip was prepared by sequencing 320 cotton genotypes found in India, which resulted in 40 lakh single nucleotide polymorphisms (SNP), a variation in the DNA sequence at a single base position. Out of these, 90K SNPs were shortlisted as the best markers.Lucknow: CSIR-National Botanical Research Institute (NBRI), Lucknow, has developed a special chip that will assist scientists and farmers in cultivating superior cotton plants.Upon insertion of this ‘90K SNP Cotton Chip' in special equipment, it will provide data about various cotton varieties and their characteristics.
