Field comparison experiments showed that the new strain group was neat, with a similar growth period to 9311, a plant height of about 125 cm, an ear length of about 26 cm, and no significant difference in the total number of grains and fruiting rate per ear were from 9311, and a thousand grain weight was about 27 g, which all maintained the characteristics that high-yield indica rice should have. In terms of rice quality, after rice milling test, the roughness and refined rice rate of the new product were comparable to 9311. The rice grains looked crystal clear and the length and width ratio were normal. There was no problem of rice quality decline caused by the introduction of disease-resistant genes. 7 Promotion and Application and Social and Economic Impact 7.1 Farmer adoption rate and production promotion model After successfully breeding new rice varieties that are resistant to bacterial stripe disease, the key to converting their results into productivity lies in effective promotion and application. Generally speaking, if the disease-resistant varieties can be equal to or better than the farmers' habitual varieties in terms of yield and quality, and significantly reduce the loss of disease and the cost of prevention and control, farmers will be happy to accept planting. Therefore, in the early stage of promotion, we should focus on demonstrating and comparative experiments of new varieties, so that farmers can intuitively see the benefits of planting disease-resistant varieties. In addition, agricultural technology departments and scientific research institutions need to provide corresponding supporting services and guidance during the promotion process. For new disease-resistant varieties, farmers may be concerned about their cultivation points and their adaptability to existing farming habits. Technical personnel should promptly summarize the cultivation technical regulations of the new varieties, including suitable sowing period, water and fertilizer management characteristics, comprehensive disease and insect control strategies, etc., compile and copy them into easy-to-understand materials and distribute them to farmers, or teach them through rural technical training meetings, field schools, etc. This will help farmers correctly plant new varieties and fully utilize their potential to increase production and resist diseases. In terms of promotion model, it can be promoted in combination with national and local agricultural projects. For example, new disease-resistant varieties will be included in the list of varieties recommended by the government agricultural industry, and key support will be provided in the construction of good varieties subsidies and demonstration counties. Organize high-yield creation activities and on-site observation meetings for new varieties to expand social influence. The main body of promotion can also be diversified, not only agricultural and rural departments, but also seed companies and cooperatives. Seed companies have channel and marketing advantages in promoting new varieties, and can enable new varieties to enter the market faster through commercial promotion. 7.2 Promoting role in regional food production security The large-scale application of disease-resistant rice varieties plays an important role in ensuring regional food security. It can significantly reduce yield losses due to disease epidemics and stabilize rice production levels. In areas with high incidence of diseases, conventional sensory varieties may reduce production by more than 20% in the epidemic year, or even no harvest of particles. After promoting disease-resistant varieties, even if the bacteria reproduce in large quantities when the environmental conditions are suitable, because the varieties themselves are resistant, only mild symptoms or no disease occurs in the field, thus avoiding catastrophic losses (Qi and Rao, 2025). Secondly, the promotion of disease-resistant varieties is conducive to expanding the rice planting area and seasons and further improving the total grain output. Some old varieties with high sensitivity can only be planted in seasons with lower risk of disease or not at all in endemic areas. Because new disease-resistant varieties "break" disease restrictions, they can be planted in a wider space and time.
