| Notes | 51-1213/S Nitrogen fertilizer postponing; Genotype; India hybrid rice; Milling quality; Appearance quality Four different genotypes of India hybrid rice were used as tested material to study, the effects of different nitrogen fertilizer postponing rate（ basic tiller fertilizer amount： ear fertilizer amount ） on the milling quality and appearance quality of Indica Hybrid Rice under the same total nitrogen amount （ 180 kg/hm^2）. The result showed that the milling quality and appearance quality were improved by nitrogen fertilizer postponing. Nitrogen fertilizer postponing had different effects on the percentage of brown rice rate, milled rice recovery, head rice rate, chalkiness degree and transparency of different genotypes. The brown rice rate and milled rice rate of II you 498, Rong 18 ,you 188 and Chuanxiang 9838 had a decrease after increasing as the nitrogen fertilizer postponing rate increased, while the brown rice rate and milled rice rate of F you 498 increased as the nitrogen fertilizer postponing rate |
