<div><strong>Background: </strong>Joha Rice are aromatic rice landraces, having small to medium grain size, indigenous to Assam, India. Due to the introduction of high yielding hybrid varieties, many endemic rice landraces including Joha Rice, are in a verge of extinction, as these can only be conserved and maintained by repetitive cultivation. As there is a conflict of local names for these landraces, many landraces with similar morphological characters have been reported from various parts. Simple sequence repeat (SSR) markers with longer perfect repeats have earlier proved successful and essential in studying the genetic diversity among rice cultivars. The present study is aimed to evaluate the genetic relationship among fifteen (15) aromatic Joha rice landraces endemic to Upper Brahmaputra Valley, Assam.<br />
<br />
<strong>Methods: </strong>In the present investigation, different landraces of Joha rice were surveyed during 2016-2019. 15 landraces were selected, based on their morphological characters and local data. The collected germplasm of Joha rice was grown in the experimental plots and DNA from young, healthy leaves were isolated which were further used for determination of genetic diversity using SSR markers. Thirty-eight SSR markers were used to evaluate the genetic relationship among the fifteen aromatic rice landraces.<br />
<br />
<strong>Result: </strong>A total of 110 polymorphic alleles were detected by 34 markers across all the landraces, with an average of 3.25 per locus. The Polymorphic Information Content (PIC) ranged from 0.24 to 0.83, with an average of 0.5 for each marker. The marker RM154, RM454 and RM489 produced maximum six alleles showing PIC value of 0.82, 0.82 and 0.83, indicating a high polymorphism. UPGMA cluster analysis using Jaccard&rsquo;s similarity index produced a dendrogram clustering the rice landraces in three major groups and five subgroups. Group II, which consisted of five sub-groups and 12 landraces, showed diverse genotypes. These landraces showed significant genetic similarities.&nbsp;</div>

<div><strong>Background:</strong> Egg albumen paneer (EAP) is a novel food product simulating the popular milk based paneer. The study was conducted to develop binders incorporated egg albumen paneer (EAP) and to find their effects on its quality characteristics.<br />
<br />
<strong>Methods:</strong> Binders used were glutinous rice flour (GRF), Joha rice flour (JRF), wheat flour (WF) and oat flour (OF) in different formulations. EAP cubes were analysed for proximate composition, sensory qualities, texture profile and colour profile. Microbiological studies of the cubes stored at refrigeration temperature were enumerated for Total Viable Plate Count (TVPC), Total Psychrophilic Count (TPC) and Yeasts and Mould Counts at regular interval upto 90 days.<br />
<br />
<strong>Result:</strong> Study revealed highest yield percentage in T<sub>3</sub> formulation. The proximate compositions for moisture, protein, fat and ash differs significantly among the different formulations. Analysis of Texture Profile found T<sub>3</sub> group with the highest value for hardness, chewiness and resilience quality while T<sub>2</sub> group was found for springiness and cohesiveness, while no significant difference was found for colour profile for any of the formulations. The microbial counts were within the acceptable range. It can be concluded that Egg Albumen Paneer could be prepared satisfactorily by incorporating different combinations of cereal flours.</div>

<div style="text-align: justify;">A field experiment was carried out during kharif, 2012 to summer, 2013 under rainfed condition in the organic block of Assam Agricultural University, Jorhat to find out the effect of different green manuring practices and other organic sources of nutrient on productivity of scented (joha) rice and their residual effect on linseed crop. Results revealed that though green manuring practice had no significant effect on yield and yield attributes of both scented (joha) rice and succeeding relayed linseed crop but higher values were recorded with the incorporation of dhaincha as in-situ green manuring in respect of all the yield attributes and yield of both the main and succeeding crops. Among various organic sources of nutrient, application of enriched compost produced the highest yield in both scented rice as well as linseed crop. The increase in grain yield of scented rice with enriched compost over the other sources of organic nutrient and control treatment ranged from 7.33 to 30.04 per cent. The corresponding increase in case of linseed crop ranged from 29.1 to 39.8 per cent which reflected better residual effects of both the sources of nutrient on linseed crop. The residual available nutrient contents in soil after harvest of linseed crop showed similar trends and increased all the major nutrients over their initial status.</div>
