Abstract

Abstract:

Soft rice is a unique, high-quality rice germplasm resource with a long history of cultivation in Yunnan Province, China. It is important to study the grain starch quality characteristics for elucidating the mechanism of high-quality rice and improving rice taste. In this study, 36 Yunnan soft rice landraces and control materials including high-amylose content (high-AC) rice varieties, glutinous rice varieties, Yunnan soft rice cultivars and other cultivars were planted and harvested in different environments. The apparent amylase content (AC), gel consistency (GC), gelatinization temperature (GT), and rapid visco analyzer (RVA) profile characteristics were determined and analyzed using correlation and variance analysis. The main starch quality characteristics of the 36 Yunnan soft rice landraces were that the AC and GC were in the middle; the GT was the highest, but there were no significant differences with the control groups (P>0.05); in the RVA profile, the peak viscosity (Peak-1) and breakdown value (Breakdown) were more higher, the hot paste viscosity (Trough-1), final viscosity (Final-Visc), and setback value (Setback), peak time (Peak-Time) and pasting temperature (Pasting-Temp) were basically between high-AC and glutinous rice varieties. Variance analysis indicated significant differences in Trough-1, FinalVisc, and Setback of RVA profile between the Yunnan soft rice varieties (general term for Yunnan soft rice landraces and Yunnan soft rice cultivars) and high-AC rice varieties, glutinous rice varieties, and other cultivars. Correlation analysis showed that there were significant correlation between AC and the RVA in Yunnan soft rice varieties (P<0.05), especially landraces. In addition, the starch quality of the Yunnan soft rice landraces were most affected by the environment compared with those of the control groups. In all 10 traits, except GT, 9 traits had showed significant differences between different environments (P<0.05). The starch quality of the Yunnan soft rice landraces were found to be related to their original sites: significant differences of starch quality were found between landraces from the paddy and upland rice planting region in the south margin and the single or double-season indica rice planting region in southern Yunnan. In summary, it is concluded that AC can be used as a basic index, Trough-1, FinalVisc, and Setback of RVA profiles should also be considered as auxiliary indexes for describing the main starch quality characteristics of Yunnan soft rice varieties. Moreover, it should also be noted that the starch quality of Yunnan soft rice landraces is strongly influenced by environmental factors. It is difficult to breed wide adaptable soft rice varieties.
