“…It is a home for aromatic rice diversity (Bisne and Sarawgi, 2008) and grown in almost all the states, covering more than 30 per cent of the total cultivated area (Adhikari et al, 2012;Sarma et al, 2016). From the agro horticultural view point North east is the richest reservoir for genetic variability in aromatic rice crops (Hore 2005). Because of the special flavour and economic value, aromatic rice bears special significance in the present globalized era.…”

Rice is one of the major cereal grain consumed more than half of the world's population. Aromatic rice is one of the most widely accepted rice due its pleasant aroma. Traditionally, many varieties of aromatic rice are grown by the farmers of Assam maintaining a diverse gene pool. In the present study, morphological variation was studied in 22 aromatic rice landraces using qualitative and quantitative traits. Keteki Joha is very popular indigenous aromatic rice grown in a small pocket of Assam for its high yield. Though Kola Kunkuni Joha is relatively smaller grain size and low yield but have high demand due to its high aroma as compared to other landraces. Significant positive correlations was occurred at 0.05 level between kernel length and seed weight with seed width (r = 0.6734*) and (0.5881*) as well as seed weight with kernel width (r = 0.5433*). The correlation between seed width and kernel width (0.9663**) showed significantly positive relationship which shown at 0.01 level. Characterization of aromatic rice landraces of Assam would be a boon for the breeders for designing further rice improvement programme.

“…Their human trial showed increased level of ferritin in the blood of the anemic subjects (Annual Report, IRRI) which is an indication of improving helping eradicating anemia for the rice eating population in the world. (Hore, 2005). However the processing and nutritional qualities of such genotypes are still not studied.…”

Searching rice cultivars or variety with good processing and high in important essential nutrients are prime important in the present context of rice research. The north eastern hill region of India which is a mega biodiversity hot spot of the world has numerous cultivars of rice with tremendous potential of high quality rice. Eighteen indigenous cultivars of Tripura, a north eastern hill state of India were subjected to the study. Majority of the cultivars were of short bold grain type. Eleven cultivars were aromatic type with one cultivar of strong aroma comparable to Basmati rice. Eleven cultivars were found to possess higher hulling percentage more than 65% and six cultivars with more than 65% out turn. Majority of the cultivars had low amylose contents (<20%). Four cultivars were having higher total crude protein (>10%), six cultivars were having higher iron contents (>10ppm). In most of the characters, heritability (h 2 ) was more than the genetic advance indicating more of environmental effect. Amylose, crude fibre and iron, genetic advance was high; selection for these traits will improve the genotypic value of selected plants over the parents. High heritability coupled with high genetic advance was found in iron and amylose. The association of crude protein is significant but negative with carbohydrates and amylose, while with crude fat and zinc, the association is significant and positive. Carbohydrate was significantly and positively correlated with ash percent and iron concentration and negatively associated with total fat. There was no significant correlation between carbohydrate and amylose.
