Abstract
A study was undertaken to evaluate the morphological parameters, dry matter production and yield in eight aromatic rice genotypes during Kharif 2010-2011. The aromatic rice genotypes differed significantly with respect to plant height, number of tillers, number of leaves, ischolar_main parameter (ischolar_main length, ischolar_main volume and ischolar_main weight), area of top three leaves including flag leaf, yield and harvest index. Results on morphological characteristics measurement showed that highest plant height and lowest plant heights were recorded in genotype Chittimuthyalu and RNR 2378, respectively. Maximum number of tillers and number of leaves were recorded in genotype RNR 2354. Root parameters like ischolar_main length, ischolar_main volume and ischolar_main weight were highest in genotype RNR 2354 and lowest in Pusa1121. Maximum combined leaf area of first three leaves from the top including flag leaf were found in genotype RNR 2354 and minimum was recorded with genotype Pusa1121. Highest dry matter and grain yield were recorded in genotype RNR 2354 and the lowest grain yield was recorded by Pusa 1121. Root volume, ischolar_main weight, ischolar_main length, number of leaves, number of effective tillers and flag leaf area were found positively associated with dry matter production and grain yield in aromatic rice.
