    摘要:

    稻谷储藏过程的陈化变质对水稻生产和经营造成严重损失,开展稻谷耐储藏性研究对耐储藏水稻品种筛选具有重要意义。本研究利用197份半糯粳稻、117份普通粳稻和14份糯稻为试验材料,采用人工高温高湿陈化方法,以耐储藏指数陈化前后发芽率降低百分率(SDI)作为评价指标,分析了半糯粳稻与普通粳稻及糯稻间的耐储藏性差异。根据SDI高低,供试材料可分成4类:第I类高耐储型23份,75%≤SDI<100%,包含半糯粳稻8份和普通粳稻15份;第II类较耐储型77份,50%≤SDI<75%,包含半糯粳稻32份、普通粳稻44份和糯稻1份;第III类较不耐储型118份,25%≤SDI<50%,包含半糯粳稻82份、普通粳稻32份和糯稻4份;第IV类不耐储型110份,0≤SDI<25%,包含半糯粳稻75份、普通粳稻26份和糯稻9份。结果表明半糯粳稻总体上的耐储藏性低于普通粳稻,而糯稻更不耐储。对材料生育类型间的耐储藏性分析显示半糯粳稻和普通粳稻中仅早熟中粳稻型表现较低。陈化前后稻谷新鲜度值降低百分率(RPFV)进一步验证半糯粳稻耐储藏性高于糯稻而低于普通粳稻。通过SDI和RPFV综合评价,筛选到高耐储藏的半糯粳稻4份(BG26、BG69、BG81和BG164),普通粳稻9份(南粳晴谷、CG10、CG23、CG25、CG28、CG32、CG38、CG49和CG71)。研究将为改良水稻品种的耐储藏特性以及发掘耐储藏基因资源提供材料来源。

    Abstract:

    Grain quality deterioration during rice aging storage has caused serious losses to rice production and management. It is of great significance to carry out research on storage tolerance and identify rice varieties with high storability. In this study, 197 semi-waxy japonica varieties, 117 common japonica varieties and 14 waxy japonica varieties were used. The storage tolerance characteristics was analyzed at the artificial high temperature and high humidity condition using the evaluation index of the storage tolerance index (SDI) that defines based reduction percentage of germination rate before and after aging. According to SDI, these genotypes were divided into four groups: group I was the high storability type, 75%≤SDI<100%, including 8 semi-waxy japonica rice and 15 common japonica rice; group II was the relative storability type, 50%≤SDI<75%, including 32 semi-waxy japonica rice, 44 common japonica rice and 1 waxy rice; group III was the less storability type, 25%≤SDI<50%, including 82 semi-waxy japonica rice, 32 common japonica rice and 4 waxy rice; group IV was non-storability type, 0≤SDI<25%, including 75 semi-waxy japonica rice, 26 common japonica rice and 9 waxy rice. The storage tolerance of semi-waxy japonica rice, which was higher than that of the waxy rice, was lower than that of common japonica rice. The analysis of storage tolerance among different growth-development types showed that only the early-maturing medium type in both of semi-waxy and common japonica rice had the lowest storability value. Using the reduction percentage of freshness value (RPFV), semi-waxy japonica rice showing lower storability than common japonica rice and higher storability than waxy japonica rice was observed. Through the comprehensive evaluation of SDI and RPFV, four semi-waxy japonica rice (BG26, BG69, BG81 and BG164) and nine common japonica rice (Nanjing-qinggu, CG10, CG23, CG25, CG28, CG32, CG38, CG49 and CG71) were obtained with high storability. Collectively, the research provided germplasm materials applicable for the storability improving of rice varieties and exploring the storage tolerance gene resources.
