Genotypic differences in grain quality including protein, micronutrient concentrations and few of the yield attributing parameters of twenty one popular rice hybrids were assessed. The data revealed huge variations in grain quality among the hybrids. All hybrids tested have statistically similar milling percentage (70.1- 72.9 per cent). Head rice recovery of PA 6444 being the highest (70.9 per cent) at par with 15 hybrids was significantly higher than Sahyadri-4, Indirasona, HSD-1 and CORH-3. Most of the grain types of the hybrids were classified as long slender types. Highest water uptake was exhibited with Pusa RH-10 and PSD-3. Protein content varied by 4.05 per cent among the hybrids ranging from 5.74 per cent in PSD 3 (lowest) to 9.79 per cent in DRRH-2 (highest). Mean micronutrient iron concentration of hybrids (68.4 ppm) was found to be 1.83 times that of zinc (37.3 ppm). Two hybrids with both high iron and zinc concentration (DRRH-2 with 125.8 ppm and 43.8 ppm; and Sahyadri-4 with 104.8 and 43.0 ppm) were identified.
