Abstract:

The experiment on 110 genotypes (aromatic and non-aromatic rice) along with three checks viz., Sarjoo 52, FL 478 and CSR 10 of rice (Oryza sativa L.) was conducted to work out the genetic variability, heritability and genetic advance effects of their various attributes on grain yield. The high estimates (>20%) of phenotypic (PCV) and genotypic (GCV) coefficients of variation were recorded in case of grains per panicle (PCV=28.201%, GCV=28.147%), spikelets per panicle (PCV=26.220%, GCV=26.187%), flag leaf area (PCV=26.199 %, GCV= 25.084%), biological yield per plant (PCV=23.935%, GCV=23.870%) and grain yield per plant (PCV=21.375%, GCV=21.245%). High estimates of broad sense heritability (> 75%) were recorded for spikelets/panicle (99.75%), grains/panicle (99.62%), biological yield/plant (99.46%), 1000-grain weight  (99.29%), days to 50%  flowering (99.26%),  grain yield/plant (98.79%), panicle length (98.22%),  spikelet fertility (96.86%), harvest index(95.70%),  chlorophyll content (94.06%) , leaf nitrogen (91.90%),  flag leaf area (91.67%) , L/B ratio (79.31%) and leaf temperature (77.92%). The high estimates of genetic advance in per cent of mean (>20%) were recorded for grains/panicle (57.8734%), spikelets/panicle (53.8776%), flag leaf area (49.4721%), biological yield/plant (49.0373%), grain yield/plant (43.4988%), leaf nitrogen(29.1598%),  L/B ratio (23.1016%),  panicle length (21.1853%), panicle bearing  tillers/plant (20.5318%). High heritability and genetic advance indicate that the additive nature of gene action and reliability of those characters for selection and emerged as ideal traits for improvement through selection.
