摘要： 测定早造种植收获的42个恢复系和7个不同蒸煮及食味对照稻米淀粉RVA谱特征值，对其进行了相关分析和系统聚类分析。结果表明如下：（1）恢复系RVA谱特征值变异系数最大是SBV，依次是BDV，CSV，CPV，HPV，最小是PKV。（2）各RVA谱特征值表现较好相关性。RVA谱特征值3个基本粘度间，只有HPV与CPV表现极显著正相关。PKV与BDV呈极显著正相关，与SBV和CSV均分别呈极显著负相关；HPV、CPV与BDV分别呈显著、极显著负相关，HPV、CPV分别与SBV和CSV均呈极显著正相关。BDV、SBV和CSV均分别呈极显著负相关，而SBV和CSV呈极显著正相关。（3）RVA谱特征值可分为3大类型，三类型区分主要依据SBV，Ⅰ类型SBV最高(37.4RVU～156.8RVU)，Ⅱ类型SBV最低(-141.2RVU～-86.0RVU)，而Ⅲ类型SBV介于两者之间(-83.6RVU～23.7RVU)；在两极端类型Ⅰ类型和Ⅱ类型之间区分还可依据BDV和CSV指标。Ⅰ类型亚类间区分主要依据PKV和CPV，Ⅱ类型亚类区分依据PKV，Ⅲ类型亚类区分则比较复杂，依据PKV、HPV、BDV、SBV和CSV指标组合。

Abstract: In rice quality improvement, starch pasting viscosity tested by Rapid Visco Analyser(RVA) servers as important index in estimating the eating and cooking quality of rice. The objectives of this study were to investigate analyze their correlations and clusters using restore lines of hybrid rice in indica and their check (CK) with different eating and cooking quality. The results showed as follows: (1) Setback (SBV) had largest coefficient of variation, followed by breakdown (BDV), consistence (CSV), paste viscosity (CPV), hot paste viscosity (HPV) and peak viscosity (PKV). (2) The tight relationship among RVA profiles was found. There were very significant（P＜0.01） positive correlations among HPV , CPV, SBV and CSV, between PKV and BDV., significant（P＜0.05） negative correlation between HPV and BDV, very significant negative correlations between BDV and CPV, SBV,CSV respectively. (3) Restore lines of hybrid rice in indica and their CK could be clustered into three types based on starch RVA profiles. Every type had also clustered into two subtypes. There were distinctions in three types based on SBV. The first(Ⅰ) type had highest SBV(37.4RVU～156.8RVU)，the second (Ⅱ) lowest(-141.2RVU～-86.0RVU).The third(Ⅲ) type had SBV in betweenⅠtype and Ⅱtype(-83.6RVU～23.7RVU). There were distinctions in two subtypes of Ⅰtype based on PKV and HPV, two subtypes of Ⅱtype based on PKV . However, There were distinctions in two subtypes of Ⅲ type based on combination of PKV, HPV, BDV, SBV and CSV.
