The Institute has maintained a set of regional stations since 1928. These stations were initially established as field units at important cotton breeding centres for the purpose of preliminary screening of experimental strains of cotton. These units were carrying out tests for fibre properties of newer varieties cotton under development. Even though locations where the regional unts functioned have undergone changes over the time, they continue to be an important component of cotton research in India. At present the institute maintains regional centers at Sirsa, Surat, Nagpur, Guntur, Dharwad, and Coimbatore. Nagpur unit also have Ginning Training Centre (GTC) and other facilities.
