Comparison of Head Mill Rice Rate(HMRR)and Selection of High HMRR Varieties for 357 Indica Rice Planted in Different Seasons in Double Cropping Area of South China
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.
