Abstract High temperature (HT) accompanied with strong light (SL) often occurs in early indica rice production during
grout filling stage in southern China, which accelerates grain ripening. Two indica rice cultivars with different
amylose content (Zhongjiazao17, ZJZ17, high amylose content; Xiangzaoxian45, XZX45, low amylose content)
were grown under control (CK), HT, and HT+SL conditions during grout filling to determine the effects on grain
yield and quality of rice. The results showed that compared with CK, HT and HT+SL significantly reduced the
1000-grain weight and filled grain rate whether in high or low amylose content early indica rice cultivars… More >
