In order to promote the process of improving the grain quality of rice, Guangdong Province has started to set up a regional trial of fragrant rice group since 2018. Yuexiang 430 was the first batch of fragrant rice varieties tested and successfully approved by Guangdong Provincial Crop Variety Appraisal Committee. Yuexiang 430 is a thermo-sensitive rice variety with moderate plant-type, strong lodging resistance, high yield and fine quality. The results of the regional test showed that the average yield of Yuexiang 430 reached 456.3 kg/667 m2, ranking the first in the regional trail group, which was significantly higher than that of the control variety Meixiangzhan 2. The grain quality of Yuexiang 430 reached the first grade standards of high grain quality rice issued by Chinese Ministry of Agriculture and Rural Affairs, with amylose 16.2%, length-width ratio 3.3 and aroma (2-AP content 675.0~1 030.9 μg/kg), taste score 84.0~91.0, cooked rice is soft, smooth taste and fragrant, and has won the gold award of the First Conference of Guangdong Rice Industry Development. Yuexiang 430 exhibited strong disease resistance to rice blast in the field tests with leaf blast of grade 1.4~3.0 and neck blast of grade 3.0~3.4, and was easily planted and managed for both early and late cropping seasons in Guangdong Province. Yuexiang 430 has performed well in the trials of Yangshan, Huazhou, Xinhui, Maoming and Nanxiong, etc, in Guangdong Province, and has been used for production and processing in many “Guangdong Simiao Rice” industrial parks, and has an excellent prospect of promotion and application.
