摘要:

以36份北方两系杂交粳稻组合和4个常规粳稻品种为试验材料,测定稻米的RVA谱特征值、直链淀粉含量、蛋白质含量和米饭食味品质,并对RVA谱各特征值之间及其与直链淀粉含量、蛋白质含量和米饭食味品质之间的相关性进行研究。结果表明,多个RVA谱各特征值之间相关性显著;直链淀粉含量与消减值、回复值、糊化温度呈显著正相关,而与崩解值和峰值黏度呈显著和极显著负相关;蛋白质含量与最低黏度和峰值时间呈显著和极显著正相关,与其余RVA谱特征值间均无显著相关性;米饭食味值与峰值黏度、崩解值呈极显著正相关,而与消减值、回复值、糊化温度呈极显著负相关。RVA谱特征值能充分反映稻米食味品质的优劣,可以作为优质两系杂交粳稻选育的主要依据。

Abstract:

A field experiment was conducted using 36 cross combinations of two-line japonica hybrid rice and 4 conventional japonica rice varieties in Northern China, the RVA profile characteristics, amylose content, protein content and eating value of rice were measured, and the correlation of which were analyzed. The results showed that there existed significant correlation among multiple RVA profile characteristics. Amylose content had significantly positively correlation with setback, consistency, pasting temperature, respectively, whereas amylose content had significantly or very significantly negative correlation with breakdown and peak viscosity. Protein content had significantly or very significantly positive correlation with trough viscosity and pasting temperature, protein content had no significant correlation with the rest of RVA profile characteristics. The palatability value of cooked rice had very significantly positive correlation with peak viscosity and breakdown. Moreover, the palatability value of cooked rice had very significantly negative correlation with setback, consistency, pasting temperature, respectively. RVA profile characteristics could fully reflect the advantage and disadvantage of eating value, and it could be used as the main basis of breeding fine quality two-line japonica hybrid rice.

Key words: japonica two line hybrid rice, RVA profile characteristics, eating quality
