A total of 30 Jhum rice landraces were collected from Rangamati districts of Bangladesh during 24-28 October, 2015 by Dr M Z Islam and colleagues, Bangladesh Rice Research Institute (BRRI) under Asian Food and Agriculture Cooperation initiative (AFACI) project. All rice landraces were grown under Jhum. Fresh seed stocks for each landrace were collected from fields and farmer’s store. The collected landraces have been conserved at short term storage of the BRRI Genebank. The collected Jhum rice landraces were characterized for agro-morphological traits. These studies were conducted in RCB design with three replications at the experimental field of BRRI, Gazipur, during March to July (Aus season) 2016. Twenty-day-old seedlings from each entry were transplanted using single seedling per hill in 2.4 m2 plot. Row to row and plant to plant distances were maintained as 25 cm and 20 cm, respectively. Fertilizers were applied @ 60:20:40:12 kg N, P, K and S per hectare. All the fertilizers except N were applied at final land preparation. Nitrogen was applied in three equal splits, at 15 days after transplanting (DAT), at 35 DAT and just before flowering. Intercultural operations and pest control measures were done as and when necessary. Twenty-three qualitative traits namely blade pubescence, blade colour, leaf sheath: anthocyanin colour, basal leaf sheath colour, flag leaf angle, ligule colour, ligule shape, coller colour, auricle colour, culm:anthocianin colouration of nodes, culm angle, internode colour, culm strength, panicle type, panicle exertion, spikelet: awns in the spiklet, distribution of awing, awn colour, apiculus colour, stigma colour, lemma and palea colour, seed coat (bran) colour and leaf senescence were scored based on ‘Descriptors for cultivated rice (Oryza sativa L.)’ issued by GRSD, BRRI (2018). Again, specifically ten plants from each entry were randomly selected for recording data on 15 quantitative traits namely, flag leaf length, flag leaf width, leaf area index, culm diameter, plant height, effective tiller number, panicle length, days to flowering, days to maturity, filled grains per panicle, grain length, grain breadth, length-breadth ratio, 1000 grain weight (TGW) and yield per hill. Genetic diversity was worked out by the principal component analysis (Rao, 1964) and Mahalanobis’ generalized distance (D2) analysis (Rao, 1952). Intra and inter cluster distances were calculated by the methods of Singh and Chaudhury (1985). Under multivariate analysis principal component analysis (PCA), principal coordinate analysis (PCoA), cluster analysis (CA) and canonical vector analysis (CVA) were done by using GENSTAT 5.5 programme.
