“…The present study exhibited high variability in most of the observed qualitative traits of aus rice landraces. Similar types of work was also reported by other authors (Bisne and Sarawgi, 2008;Moukoumbi et al, 2011;Ahmed et al, 2016;Mau et al, 2017;Akter et al, 2017).…”

Genetic diversity in 31 traditional Bangladeshi Aus rice genotypes were studied under transplanted condition through Mahalanobis D 2 statistic for grain yield and yield contributing characters. The genotypes were grouped into five clusters. The inter-cluster distances were higher than intra-cluster distances indicating wider genetic diversity among the genotypes of different clusters. The intracluster distances were lower in all the cases reflecting homogeneity of the genotypes within the clusters. The cluster II contained the highest number of genotypes (08) and the cluster I and III contained the lowest (05). The highest intra-cluster distance was noticed for the cluster II and the lowest for cluster IV. The highest inter-cluster distance was observed between cluster II and V followed by cluster III and V, cluster I and V and the lowest between cluster I and III. Regarding inter-cluster distance, the genotypes of cluster V showed high genetic distance from all other clusters. The genotypes from cluster V could be hybridized with the genotypes of other characters of other clusters for producing transgressive segregants. The highest cluster means for yield, effective tiller number and grain length, were obtained from cluster I; whereas the lowest mean value for yield, culm length, plant height and grain breadth were found in cluster II. Therefore, genotypes under cluster I, cluster II and cluster V might be selected for future breeding program as parents for crossing to produce new recombinants with desired traits.

“…Also the variability in most of the observed qualitative traits of aromatic rice germplasm was exhibited in our study. Similar studies were also reported by other researchers (Ahmed et al, 2016;Mau et al, 2017;Akter et al, 2017 andIslam et al, 2017). However, Islam et al (2018a) found that variation for leaf blade colour, lemma-palea colour, apiculus colour, lemma-palea pubescence and seed coat colour in similar named of aromatic rice landraces.…”

The agro-morphological characterization of germplasm is of utmost importance to generate information to be utilized in plant breeding programmes. The aim of this study was to characterize the agro-morphological traits of 113 accessions of aromatic germplasm (Oryza sativa L.) based on qualitative agro-morphological descriptors. No duplicates were identified among the studied accessions for qualitative traits in the cluster analysis, which means there is a high diversity among the accessions for these traits. Following UPGMA cluster analysis, 113 accessions of aromatic germplasm formed ten distinct clusters. The highest numbers of germplasm (96) were found in cluster IXd, 2 were found in cluster III, IV and VI, 3 were found in IXc and the lowest number of germplasm (1) in cluster I, II,V, VII, VIII, IXa, IXb and X, respectively. Aroma evaluation revealed that 67 germplasm were scented, 34 were lightly scented, while the rest 12 germplasm were nonscented. Germplasm namely Begun bichi, Elai, Chinigura, Basmati 370, Ranisalut, Sakkorkhora, Jirakatari, Raduni Pagal, Kalijira (long grain), Black TAPL-554, Kalgochi, BRRI dhan34, BRRI dhan50, Badshabhog-2, Tulsimala-2, Kataribhog, BU dhan2R , Sakkorkhana, Maloti, Bashful could be used for further improvement for incorporating aroma to the high yielding varieties.

“…Among the 30 landraces, various colours were observed in husk (lemma and palea) of different landraces. Akter et al (2017), Mau et al (2017), Ahmed et al (2016b), Nascimento et al (2011) and Moukoumbi et al (2011). However, Ahmed et al (2015a) characterized 21 genotypes of similar or duplicate named Kartiksail rice germplasm of Bangladesh and showed no anthocyanin colour in auricles, weak and medium intensity of anthocyanin colour in basal leaf sheath (each 5%), green leaf blade colour (47%) and white colour of stigma (90%).…”

Genetic diversity of 30 Jhum rice landraces was studied under irrigated condition through Mahalanobis D2 statistic for agro-morphological characters. The landraces were grouped into five clusters. The intercluster distances were higher than intra-cluster distances indicating wider genetic diversity among the landraces of different clusters. The intra-cluster distances were lower in all the cases reflecting homogeneity of the genotypes within the clusters. The principal component analysis exposed that the first five components with vector values > 1 contributed 81.14% of the total variations. The highest number (8) of landraces was observed in cluster IV and the lowest (4) in cluster II. The intra-cluster distance was maximum in cluster III (1.62) containing six landraces and minimum in cluster I (0.57) having six landraces. The highest inter cluster value was 23.44 (between cluster II and V) and the lowest was 7.29 (between cluster III and IV). The highest flag leaf length, leaf area index, filled grains per panicle were found in cluster V while the lowest culm diameter, short duration, low yielding genotypes were clubbed into cluster II. Dwarf stature and lower flag leaf length were recorded into cluster I whereas the highest plant height and panicle length were obtained from cluster IV. Based on canonical vector analysis, culm diameter, days to flowering, days to maturity and length-breadth ratio had maximum contribution towards genetic divergence. Selection of parents from the clusters II and V followed by hybridization would possibly result in desirable transgressive segregants. Finally, Jhum rice landraces need to be conserved in Genebank for future breeding programmeBangladesh Rice j. 2017, 21(1): 47-57
