“…High heritability in concurrence with high genetic advance for 1000-grain weights was in accord with the ndings of Reddy et al (1997), Murthy et al (1999), Rao (2000), Mishra and Verma (2002) 2011) for length-breadth ratio. A low heritability coupled with moderate genetic advance for grain yield plant-1 was in agreement with Adjah et al (2020). Similarly, Islam et al (2015) observed high estimates of both heritability and genetic advance for grain yield kg ha-1 as obtained in the present study.…”

We carried out the morphological, biochemical, and molecular characterization of twenty cultivars of the least studied Joha (aromatic) rice indigenous to Assam. Unweighted Neighbour Joining (UNJ) clustering based on usual Euclidean distances for thirty-seven polymorphic morphological markers grouped the cultivars into three clusters with eight, eleven, and one genotype. The Joha rice cultivars showed highly significant differences for all the quantitative traits except for panicle length. The genotypic and phenotypic coefficients of variability (GCV & PCV) were high for grain yield ha-1 (24.62 & 24.85%) and filled grains panicle-1 (23.69 & 25.02%). All the traits except days to flowering and maturity, flag leaf breadth, and spikelet fertility exhibited high heritability along with high to moderate genetic advance, indicating the predominant role of additive gene action. Mahalanobis D2 analysis revealed three multi-genotypic and four mono-genotypic clusters of the cultivars. The cultivars' average polyunsaturated fatty acids were 37.9% oleic acid, 39.22% linoleic acid, and 0.5% linolenic acid. The fatty acid profile of Local Joha was superior to the other cultivars as it showed a high level of linoleic and linolenic acid and low saturated fatty acid content. Kon Joha 4 and Ronga Joha contained the highest iron (82.88 mg kg-1) and zinc (47.39 mg kg-1), respectively, while protein content of Kon Joha-1 and amylose content of Harinarayan were the highest. Joha (Bihpuria) showed the highest gel consistency of 140.50 mm. Kalijeera, Kunkuni Joha, Kon Joha-5, Manimuni Joha and Kon Joha-2 accorded a strong aroma. PCR amplified 174 alleles with a mean value of 2.64 across the 66 polymorphic SSR markers. PIC values ranged from 0.091 to 0.698, with an average of 0.326. The highly informative (PIC>0.50) markers were RM316, RM283, RM585, RM1388, RM3562, RM171, R1M30, RM118, RM11and RM29 for identification of the twenty aromatic rice cultivars. The UNJ clustering based on Jaccard's coefficients classified the cultivars into three distinct clusters with eight, ten, and two genotypes. Our study revealed the nutritional richness of these specialty Joha rice cultivars and sufficient scope for yield enhancement through their interbreeding to keep quality intact.

“…On the other hand, there were seven absolute negative correlations between grain length with grain width; grain width with grain shape and grain shape (%); grain shape with hulling % % and head rice %; amylose content (%) with milling %, head rice % and gelatinization temperature. Our results are in agreement with those of previous studies ( Sharifi and Naghi, 2011 , Futakuchi et al, 2013 , Adjah et al, 2020 , Xu et al, 2015a ). The process of producing varieties with high protein and nutrients using traditional or modern breeding methods is one of the main pillars in the development of healthy food suitable for all ages ( Watanabe et al, 2006 , Graham et al, 2001 , Gregorio et al, 2000 ).…”

“…The grain quality traits viz., grain length, breadth and length-breadth ratio, rice length, breadth, and length-breadth ratio registered high heritability coupled with the high genetic advance in consonance with the ndings of Jaiswal et al (2007), Reddy et al (2013), Fatema et al (2011) for grain length; Murthy et al (1999) and Jaiswal et al (2007) for grain breadth; and Jaiswal et al (2007) and Fatema et al (2011) for length-breadth ratio. A low heritability coupled with moderate genetic advance for grain yield plant − 1 was in agreement with Adjah et al (2020). Similarly, Islam et al (2015) observed high estimates of both heritability and genetic advance for grain yield kg ha − 1 as obtained in the present study.…”

We carried out the morphological, biochemical and molecular characterization of 20 indigenous Joha (aromatic) rice cultivars of Assam. Distinctiveness, Uniformity and Stability (DUS) characterization of the cultivars revealed polymorphism in thirty-seven traits, establishing distinctiveness for their utilization in breeding programmes. Unweighted Neighbour Joining (UNJ) clustering based on usual Euclidean distances for the polymorphic markers grouped the cultivars into three multi-genotypic clusters. The Joha rice cultivars showed highly significant differences for all the quantitative traits except for panicle length. The genotypic and phenotypic coefficients of variability (GCV & PCV) were high for grain yield ha− 1 (24.62 & 24.85%) and filled grains panicle− 1 (23.69 & 25.02%). All the traits except days to flowering and maturity, flag leaf breadth and spikelet fertility exhibited high heritability along with high to moderate genetic advance, indicating the predominant role of additive gene action. Mahalanobis D2 analysis revealed three multi-genotypic and four mono-genotypic clusters of the cultivars.
