Abstract:To clarify the difference of rice quality and RVA profile parameters between ratoon rice and late rice, we studied Huanghuazhan,Tianyouhuazhan,Nongxiang 32,Taiyou 390,Yongyou 4149 and Xiangwanxian 17 in Yongan Town research base of Liuyang city in 2018. Three planting modes: ratoon rice, single season late rice, and double season late rice were adopted in the experiments. Results:the head rice rate of ratoon rice was 16.8% higher than double late rice, however, there was no significant difference between ratoon rice and single season rice. The chalkiness and chalky grain rate of ratoon rice were 7.7% and 15.9% lower than double season late rice, the difference between ratoon rice and single season rice is small. Amylose content of ratoon rice was 3.3% lower than double late rice, but it was 2.9% higher than single season late rice. The gel consistency of ratoon rice was 1.9% higher than single season late rice, 3.0% higher than double late rice. There was no significant difference in RVA profile parameters among six varieties under ratoon rice and single season late rice cultivation, but the peak viscosity and disintegration values of single season late rice were significantly higher than those of double season rice. In conlusion, the rice quality of ratoon season was between single season late rice and double season late rice with a stable performance.
