不同类型东北粳稻品种食味及品质性状的研究

摘要

对东北不同穗型及粒型水稻品种食味值及品质性状进行了测定分析。结果表明，半直立穗短粒型和弯穗短粒型品种食味值高于直立穗短粒型及弯穗长粒型品种；食味值与蛋白质含量呈极显著负相关，大多数蛋白质含量高的品种食味值较低；食味值与糙米率呈显著正相关，糙米率高的品种食味值较高；食味值与直链淀粉含量呈二次曲线关系，直链淀粉含量适当的品种食味值普遍较高。%The eating value(EV) and quality traits in different types of japonica rice in northeastern China were analyzed in this pa-per. The result showed that EV of varieties with semi-erect, or curved panicle and short grain were better than that of erect panicle and short grain, or curved panicle and long grain. The EV was very significant negative correlated with protein content (PC), and sig-nificant positive associated with brawn rice rate (BRR), and significant simulated in quadratic equation with amylose content(AC). The eating quality of variety with low PC, high BRR and suitable AC is better.
