| 摘 要： | 目的]对紫叶水稻突变体PLM品质进行研究,为紫色水稻的应用研究提供依据。方法]以一种新发现的水稻紫色突变体以及与其组配的F1、F2为材料,测定其籽粒的粒型、垩白粒率、垩白度、千粒重、糙米率、蛋白质含量、直链淀粉含量、糊化温度、胶稠度等指标。结果]亲Z的粒型1级,糙米率1级,垩白粒率、垩白度、直链淀粉含量和胶稠度均未达到1级标准;F2代籽粒变大、直链淀粉含量降低、垩白度和垩白粒率降低、胶稠度变软。结论]亲Z品质指标多数未达到标准,但其F2代品质有所优化。

| Abstract: | Objective] The aim was to carry out the quality research on a purple leaf mutant （PLM） of rice and provide the basis for applied research of purple rice.Method] A newly discovered purple mutant of rice and its hybrid filial generations （F1 and F2） were employed as the experimental materials to determine its characteristic indexes,such as grain type,chalky grain rate,chalkiness,1 000-grain weight,brown rice percentage,protein content,amylose content,gelatinization temperature and consistency.Result] The grain type and brown rice percentage of the parent （pro-Z） both reached standard of Ⅰ Grade,while chalky grain rate,chalkiness,amylose content and consistency did not meet the requirements of the standard.The F2 generation displayed some optimized properties,including larger grain,lower amylose content,reduced chalkiness,lower chalky grain rate and softened consistency.Conclusion] The majority of the characteristic indexes of pro-Z did not meet the requirements of standard,but the qualities of F2 generation were all optimized to some extent. |
