Abstract
Aromatic rice is a special group of rice and considered the best in term of significant quality traits of rice and aroma. In this study sixteen advance lines of rice were evaluated for physical grain quality, aroma, gene of fragrance and yield attributed traits. Physical grain quality includes grain length, L/B ratio and grain width were significantly higher in Line 67 [7.73mm (SD0.06)], Line 4 [1.601mm (SD0.102)] and Line 4 [3.4mm (SD0.02)]. Cooking time was positively correlated with gelatinization temperature (GT). The test advance lines were classified into, three groups: four at the advance lines were high GT, six with intermediate and six with low GT. High GT advance lines were recommended for parboiling. Out of sixteen advance lines showed aroma by conventional approaches; eleven lines were confirmed with the presence of fgr gene for aroma. The rest of the advance lines were non-aromatic with lacking fgr gene. The advance lines of rice were evaluated for yield attributing traits include, panicle length-1, filled spikelet’s panicle-1, unfilled spikelet’s panicle-1, primary branch panicle-1 and secondary branch panicle-1 were significantly higher in Line 67 [33.153 cm (SD0.73)], Line 4 [398.22 cm (SD2.69)], Line 69 [109.78 cm (SD8.27), Line 36 [21.7 cm (SD0.509)] and Line 182 [79.2 cm (SD2.499927)] respectively. The productive tillers plant-1 and yield plant-1 were significantly higher in Line 21 [16.0 cm (SD9)] and Line 4 [448.88g (SD6.63)]. The results of this study indicated the excessive genetic potential of genotypes study. The promising genotypes recognized through the present study can be used in future breeding programs for the productive and quality result.
