辽宁省稻米蒸煮品质性状研究

以近年来辽宁省审定的61个水稻品种为试材,对辽宁省水稻品种蒸煮品质性状的现状及性状间的关系进行了分析。结果表明:辽宁省水稻品种间蒸煮品质性状差异较大,碱消值、直链淀粉含量优质率较高,直链淀粉含量与胶稠度存在着显著正相关。高直链淀粉含量的品种易出现较低级别的碱消值,中、低直链淀粉含量的品种则易出现较高级别的碱消值,这可作为间接选择的依据。辽宁省稻米蒸煮品质改良的重点应放在选择中、低直链淀含量的品种,并协调直链淀粉含量与胶稠度之间的关系。

Study on Cooking Quality of Rice in Liaoning

The current status of cooking quality of 61 rice varieties registered in Liaoning in the recent years was studied and the results showed that there existed great differences of cooking quality among rice varieties in Liaoning,the fine quality rates of alkali spreading value and amylose content were higher.The amylose content was correlated with gel consistency positively.Varieties with high amylose contents had low alkali spreading values and varieties with mediate and low amylose contents had higher alkali...
