The rice quality reached the agricultural industry food rice variety quality standard grade 3.

（3）Disease resistance: blast resistance，total resistance frequency was 66.7%~95.8%，the resistance frequencies to group B was 66.7%～94.1%，the resistance frequencies to group C was 66.7%～100%，leaf blast was 1.2~3.0 degree，panicle blast was 1.0~1.5 degree，secondary susceptibility to white leaf blight（Ⅳtype flora was 1～5 degree，Ⅴtype flora was 1～9 degree）.

（4）Yield: in the rice area test of Guangdong province in 2017 of early season，average yield per mu was 498.75 kg，the yield was 10.03% higher than check variety（深两优58香油占），the increase in production reached an extremely significant level， in the national regional test in 2017，average yield per mu was 493.83 kg，the yield was 5.71% higher than check variety（博优998），in the rice national regional reexamine test in 2018，average yield per mu was 495.40 kg，the yield was 7.19% higher than check variety（天优华占），average yield of two regional tests was 494.61 kg，the yield was 6.45% higher than check variety（天优华占），in the rice national regional production test in 2018，average yield was 501.12 kg，the yield was 13.10% higher than check variety（天优华占）.

（5）Appropriate promotion regional: It is adapted for rice region outside of northern Guangdong，early season can be planted；plain areas of the rice-growing areas in south and southwest Guangdong，late season can be planted，double-rice region that rice blast occurring in low frequency of southern Guangxi、Hainan and Fujian can be planted in late season.

（6）Cultivation Techniques of Onion: Conventional cultivation management，pay attention to the control of rice blast、white leaf blight and brown planthopper.
