Abstract:

The head mill rice rate is one of the important traits that determine the commodity value of rice, and it is of great significance to screen varieties with high head mill rice rate planted in different environments. This study compared the head mill rice rate of 357 indica rice germplasm planted at the Dafeng Experimental Base of Guangdong Academy of Agricultural Sciences in 2021 to 2023. It was found that the head mill rice rate was the highest in the late season of 2021, followed by the early season of 2022, and the worst in the early season of 2023. Among them, 17 long grain indica rice varieties, including Taifeng B, 19 Xiang, Guanghui 6200, Yuehuangsimiao, Huaxinzhan and Xiangxuesimiao, all achieved the high-quality rice standard of GB/T 17891—2017 in 3 planting seasons, making them suitable for breeding high head mill rice rate varieties.

摘要:

整精米率是决定稻米商品价值的重要性状之一,筛选不同环境条件下种植都具有高整精米率的品种具有重要意义。本研究通过比较357个籼稻种质在广东省农业科学院大丰试验基地不同年份(2021—2023)不同季节(早、晚季)种植时的整精米率,发现2021年晚季的整精米率最好、2022年早季次之、2023年早季最差。其中,泰丰B、19香、广恢6200、粤黄丝苗、华新占、香雪丝苗等17份长粒籼稻的整精米率在3次不同种植环境下均达GB/T 17891—2017优质稻标准,适用于高整精米率水稻育种。
