辽宁滨海稻区水稻品质性状分析

Analysis of Rice Quality Traits in Coastal Rice Region of Liaoning

为了探究辽宁滨海稻区新品种(系)品质性状间的相关性,以207份水稻新品种(系)为材料进行分析,测定结果表明,品质性状指标间都存在显著或极显著相关性;糙米率平均值为81.28%,达到国家优质米一级标准。垩白粒率与垩白度呈极显著正相关;其他性状间相关系数均未达到显著水平;垩白粒率、垩白度和整精米率达标情况较差,是今后滨海稻区水稻育种品质改良的重点。

In In order to explore the correlation between the quality traits of new varieties(lines)in coastal rice area of Liaoning,207 new rice varieties(lines)were used as experimental materials.The results showed that there was a significant or very significant correlation between the quality traits and indicators.The average rate of brown rice is 81.28%,which reaches the national first-class standard of high-quality rice.The chalk white particle rate was positively correlated with chalk whiteness.The correlation coefficients between other traits did not reach significant levels;The chalk white grain rate,chalk whiteness and polished rice rate are poor to meet the standards,which is the focus of rice breeding quality improvement in coastal rice area in the future.
