Abstract: Thirty-two (32) genotypes of turmeric from all the North Eastern state of India along with Duggirala Red as check variety were evaluated for two consecutive years (2015 and 2016) at Horticulture Experimental farm, AAU, Jorhat, Assam. Significant variations in both the fresh and dry rhizome yield per hectare were observed among the different genotypes evaluated. The maximum fresh rhizome yield per hectare was recorded in the genotype TMN-2 (413.89 qtls/ha) while the minimum was recorded in the genotype TAS-14 (166.67 qtls/ha). However, the dry rhizome yield per hectare was found highest in the genotypes TPR-2 (55.35 qtls/ha) while the lowest dry rhizome yield per hectare was recorded in TNL-1 (24.02 qtls/ha). Significantly high variations was noticed for curing percentage among the different genotypes evaluated showing the highest curing percentage in the genotype TPR-2 (24.50%) and the lowest curing percentage in the genotypes TAS-6 (14.16%) The high significant variations in the curcumin content among the different genotypes studied was observed indicating the range of curcumin content varying from 1.72% to 6.51%. The highest curcumin content was recorded in the genotype TAS-9 and the lowest curcumin content was observed in the genotype TAS-3 (1.72%). The check variety also recorded a high curcumin content of 5.10%. Similarly, significant variations in oleoresin content among the different genotypes evaluated were also recorded. The maximum oleoresin content was found in the genotype TML-3 (17.52%) while the minimum oleoresin content was found in the genotype TAS-2 (7.63%). The check variety shows the oleoresin content of 12.29%.
