Abstract:
An investigation was carried out in the year 2018-19 and 2019-20 in 22 elite turmeric genotypes in terai region of West Bengal for evaluation and characterization according to DUS descriptors. The genotypes were collected from different sources from West Bengal and different turmeric growing regions of the country. The characters were evaluated on the basis of DUS descriptors which were developed by IISR (Indian Institute of Spices Research). Randomized Block Design (RBD) was adopted as statistical method for evaluation of 22 genotypes along with DMRT test for finding the statistical results of the different characters. Qualitative characters like pseudostem habit, leaf deposition, leaf margin, rhizome habit and rhizome shape were also characterized in all the genotypes and grouped according to pattern of divisions of descriptors. TCP 191, LTS-1, TCP 111, TCP 246, TCP 190, TCP 120, TCP 90, TCP 235, TCP58, TCP 232 showed better result than local check variety TCP-2 (Suranjana) after the completion of the investigation. All the varieties excelled in production than national variety PRATIVA, so they can be recommended in this terai region of West Bengal.
