本文研究了辽宁省１２个有代表性的水稻品种在相同条件下的碾磨品质、外观品质和蒸煮品质，结果表明：辽宁省主要水稻品种整精米率、胶稠度、糊化温度等品质指标较优，而垩白粒率、垩白面积则较大；弯穗型品种与直穗型品种在糙米率、整精米率、直链淀粉含量、胶稠度、精米粒长、垩白粒率、垩白面积等７个指标上区别明显，弯穗型优于直穗型，相关分析表明：精米率与粒宽、整精米率与穗颈粗、胶稠度与着粒密度、粒长与理论产量呈显著负相关，而精米率与谷粒长宽比、胶稠度与穗颈长、垩白粒率与枝梗数、垩白面积与穗颈粗则呈显著正相关。
In this paper, the milling quality, appearance quality and cooking quality of 12 representative rice varieties in Liaoning Province under the same conditions were studied. The results showed that the quality index of whole rice, gel consistency and gelatinization temperature of main rice varieties in Liaoning Province were While chalky grain rate and chalky area were larger. The ratio of brown rice rate, milled rice rate, amylose content, gel consistency, length of polished rice, chalky grain rate, chalky grain rate White area and other seven indicators were significantly different, curved ear better than straight ear type, correlation analysis showed that: milled rice rate and grain width, milled rice rate and panicle neck coarse, gel consistency and grain density, grain length and theoretical yield was While there was a significant positive correlation between milled rice rate and grain aspect ratio, gel consistency and neck length, chalky grain rate and branch number, chalky area and panicles neck.
