摘要：

对引进的5个水稻品种(系)进行了产量、品质及RVA特性研究，并对稻米的直链淀粉含量、RVA特征值及食味特性进行了相关分析，结果表明，稻米的直链淀粉含量与最高粘度呈极显著负相关，与消减值呈显著正相关，相关系数分别为r=-0.927和r=0.710，最高粘度与食味值呈显著正相关，相关系数为r=0.689。综合5个引进品种(系)产量、品质及RVA特性分析的结果可以看出：津稻1007增产最多(增产约58%)，但食味品质最差；津原E28增产较多，食味品质与对照品种相当；津原45和津原43增产较多，食味品质稍逊于对照品种；津川1号有一定程度减产，但食味品质与对照品种相当，可作为优质稻育种中间材料加以利用。

Abstract:

The yield, quality and amylographic characteristics of japonica rice varieties or line introduced from Tianjin municipality were investigated. The correlation coefficients between amylose content, RVA characteristics and its palatability characteristics of introduced japonica rice varieties (line) were studied. The results showed that amylose content of tested rice showed extremely significantly negative correlation with their peak viscosities and significantly positive correlation with their setback values, their correlation coefficients were -0.927 and 0.710 respectively. The peak viscosities of tested rice showed significantly positive correlation with their palatability characteristics and their correlation coefficient was 0.689. It was demonstrated that the variety jindao1007 had highest grain yield(increased by about 58%) and worst palatability characteristics among tested rice varieties; the variety jinyuanE28 had higher grain yield and mostly similar palatability characteristics as compared with control; the variety jinyuan45 and jinyuan43 had both higher grain yield and worse palatability characteristics as compared with control; the variety jinchuan1 might be utilized as breeding materials because of high quality but lower yield.
