Abstract [Objective] To utilize existing resources to create new excellent restoring and sterile lines, and to breed new hybrid rice varieties with high yield, quality and disease resistance. [Method] The high-yielding, large panicle and strong stem (HR1128/Chenghui 727) F3 selected line was used as the female parent and the early maturing and blast resistant Wushan silk seedling was used as the male parent. A new restoring line Zhunongzhan 110 with strong restoring ability, good combining ability and resistance to rice blast was selected through multiple generations of selection and cross testing with multiple three line sterile lines. In the multi-point comparison experiment, the combination with Zhu 99A showed the characteristics of high yield, high quality, disease resistance and lodging resistance, so it was named Zhuyou 110. In 2020-2021, Zhuyou 110 participated in regional trials of late maturing medium Indica rice in the middle and lower reaches of the Yangtze River and photosensitive late Indica rice in southern China. [Result] In the regional trial of late maturing medium Indica rice in the middle and lower reaches of the Yangtze River, the average yield of Zhuyou 110 in the two-year regional trial was 9.70 t/hm2, enhanced by 6.6% compared with CK. In the 2021 production test, the average yield was 10.13 t/hm2, enhanced by 5.9% compared with CK. It showed high yield, lodging resistance and moderate resistance to rice blast, which reached the second level of the Quality of Edible Rice Varieties (NY/T 593—2013) standard in the agricultural industry, approved by the National Crop Variety Approval Committee (Authorization code:Guoshendao 20220021). [Conclusion] Zhuyou 110 had the advantages of high yield, high quality, lodging resistance and moderate resistance to rice blast, which was suitable for planting one mid-season rice in the middle and lower reaches of the Yangtze River and double late-season rice in the southern rice region.
