dc.descriptionThe experiment entitled “Evaluation of Different Accessions of Acorus calamus Linn. for Variation in Morphological and Yield Parameters” was carried out at the experimental field of Department of Forest Products & Utilization at College of Horticulture and Forestry, CAU, Pasighat, Arunachal Pradesh located at 28.07°N, 95.33°E and 155 msl during 2021-22. The experiment was laid out in Augmented Block Design comprises of 40 accessions of Acorus calamus collected from different locations of Arunachal Pradesh, Assam and Manipur. The study was divided into two objectives viz., to study the morphological variations among different accessions of Acorus calamus L. (Sweet flag) and to study the variation in different accessions with respect to rhizome and essential oil yield. On the basis of the mean performance of the accessions studied, plant height ranged from 56.64 cm to 110.80 cm, fresh rhizome weight ranged from 17g to 159.80g, rhizome yield ranged from 761.60 kg/ha to 7159.04 kg/ha. The accessions IC-0632808 (2.80%), IC-0632810 (2.30%), IC-0632792 (2.00%) showed high oil content among all the accession studied. Variation in other morphological characters under study is also found.en_US
dc.description.abstractRhizome yield showed strong significant positive correlation with rhizome length (0.940**) followed by rhizome weight (0.926**), leaf width (0.729**), number of leaves (0.647**), leaf area index (0.558**), leaf length (0414*), plant height (0.406*), number of lets (0.338*). In rhizome asscociated traits rhizome weight showed maximum positive direct effect on oil content followed by rhizome length and rhizome width The accessions were divided into major seven clusters where maximum accessions were group in cluster 1 which consists of 16 accessions and check (Swarna swara). Cluster 5, cluster 6 and cluster 7 consist of 1 accession each. Cluster 6 showed maximum mean value for economically important below ground traits including rhizome length (74.2 cm), rhizome weight (159.80 g), rhizome yield (7159.04 kg/ha) and oil content (1.86%). The inter cluster D2 value was shown maximum between cluster 6 and cluster 3. Intra cluster distance was found highest in cluster 4. In the present study, accession IC-0362796 (7159.04 kg/ha) gives maximum rhizome yield. Accession IC-0632808 yielded maximum oil content followed by IC-0632810 and IC-0632792. The accession IC-0632808, IC-0632810 and IC-0632792 might be used for further breeding programme to obtain high oil content in future research work.en_US
