Exploration survey was conducted in Tripura state to collect, characterize and conserve the valuable traditional cultivars of desi cotton. Fourteen germplasm accessions comprising ten Gossypium arboreum L. and four Gossypium barbadense L. were collected from Gomati, Khowai, West Tripura and Dhalai districts of Tripura. The collected accessions of desi cotton (G. arboreum) represent derivatives of race ‘cernuum’ and ‘burmanicum’. The morphological variants of desi cotton were compact, having short sympodia, medium size boll with short staple fibre. The range for fibre quality traits such as fibre length (17.2 - 19.1 mm), fibre strength (15.0 - 16.7 g/tex), micronaire (>7), Elongation Index (4.1- 4.6) and Short Fibre Index (45.1 - 61.4) was recorded for desi cotton. Among G. arboreum accessions, two were naturally coloured light brown and brown linted cotton. The range of fibre quality traits with respect to fibre length (32.6 - 34.9 mm), micronaire (5.8 - 6.4) and fibre strength (21.6 - 24.7 g/tex) was recorded in G. barbadense collection. The cotton accessions were conserved in the Field Gene Bank and medium term cold storage at ICAR-Central Institute for Cotton Research, Nagpur for future utilization in cotton improvement.
