dc.description.abstractThe present investigation entitled “Morphological and nutritional characterization of red rice germplasm of Himachal Pradesh” was undertaken during kharif, 2020 to assess the morphological and nutritional parameters of red rice germplasm and to identify the potential germplasm lines for grain yield and nutritional traits. Biochemical analysis was carried out to obtain the nutritional properties among the germplasm lines. The result on analysis of variance showed a sufficient genetic variability among red rice genotypes for all the traits except for flag leaf length, harvest index, grain breadth and amylose content. High heritability coupled with high genetic advance was reported for iron content, zinc content, biological yield per plant, thousand grain weight and L:B ratio. Traits viz., days to 50% flowering, plant height, flag leaf length, spikelets per panicle, harvest index, biological yield per plant, thousand grain weight and grain length showed positive correlation with grain yield per plant. It was also observed that, protein had positive and significant correlation with zinc content but, iron content was negatively significantly correlated with zinc content. Biological yield per plant showed highest positive effect on grain yield per plant followed by harvest index, grain L:B ratio, grain breadth, days to 50% flowering, spikelets per panicle, iron content, flag leaf length, zinc content, effective tillers per plant, total tillers per plant and flag leaf width. On the basis of the mean performance for different traits, and in comparison, with best check, genotype- Deval, HPR-2913, HPR-2908 can be considered as the most promising genotypes for grain quality and nutritional traits. Besides this, genotype IC-12180 also expressed superiority for fewer grain quality and quantitative traits which can be used in future rice breeding programme.en_US
