Genetic diversity analysis of specialty glutinous and low-amylose rice (Oryza sativa L.) landraces of Assam based on Wx locus and microsatellite diversity

Mining nutri-dense accessions from rice landraces of Assam, India

“…Longvah & Prasad [ 36 ] reported a protein range of 6.2–10.2 g/100g for Arunachal Pradesh rice landraces, and Rayala et al [ 47 ] reported a mean PC value of 8.1 g/100g for Indian rice landraces from Hyderabad. Patil et al [ 48 ] reported comparable PC for Chattisgarh rice landraces, whereas a comparatively lower PC mean of 6.63 g/100g was reported for diverse Indian landraces by Roy et al [ 49 ] . The maximum PC was observed for Pakhi bora (11.8 g/100g) amongst the landraces from Assam.…”

Characterization of rice (Oryza sativa L.) landraces from Majuli and surrounding riverine ecologies in Assam: Assessment of morphogenetic variability and submergence tolerance

“…In our study, the F st value of the rice germplasm was 0.11, indicating a weak population structure, likely due to the genetic similarity between indica and aus varieties (Garris et al, 2005; Wang et al, 2018). Previous investigations with rice germplasm from Assam have reported the existence of two to three subpopulations (Choudhury et al, 2013; Roy et al, 2020; Verma et al, 2019). Analysis of molecular variance (AMOVA) in our cultivars indicated a higher proportion of variation among individuals within populations than among populations, consistent with findings from earlier studies on rice (Roy et al, 2015; Singh et al, 2016; Verma et al, 2019).…”

“…Ecotype‐wise, other cultivar groups such as joha and bora are also classified as sali . However, joha and bora cultivars are primarily selected by farmers for grain quality traits, with joha being aromatic and bora rice having sticky or glutinous characteristics (Roy et al, 2015, 2020; Verma, Chetia, Dey, et al, 2021). The observed variability in joha cultivars aligns with findings from other studies (Roy, 2018).…”

“…The preservation of traditional deep-water rice varieties, locally referred to as bao paddy, holds critical significance for the sustenance of local livelihoods. Surrounding Majuli, the region is replete with numerous rice varieties meticulously chosen by farmers for their adeptness in the riverine ecosystem, superior grain quality, and diverse array of desirable traits (Rohilla et al, 2019;Roy et al, 2020;Sharma et al, 1993).…”
