Under the situation that the development trend of double-cropping rice to single-cropping rice is inevitable and the labor shortage is increasing, breeding single-cropping rice varieties with weak photoperiodic sensitivity (PS) can alleviate the labor shortage during the sowing and transplanting period of single-cropping rice, and help stabilize and increase the planting area of single-cropping rice, and thus improve the land utilization rate. In the present study, two indica restorer lines with a homogeneous genetic background of hd1Ghd7, D71 and Zhonghui161, were used to construct a recombinant inbred lines population. Multiple sowing-date experiments were conducted to screen the lines with weak PS from the genotypic compositions of DTH8 and Hd2. The results showed that dth8hd2 and dth8Hd2 had shorter heading date in the hd1Ghd7 background regardless of sowing-date. In contrast, DTH8Hd2 and DTH8hd2 exhibited weak PS. These two compositions had longer heading date when they were sown early. With delayed sowing-date, heading date of the two combinations shorten, which secured a harvest before cold weather approaches. Compared with DTH8hd2, DTH8Hd2 exhibited longer heading date when they were sown early, ensuring the full use of light and temperature resources. Our study provide a theoretical basis for breeding single-cropping rice varieties with weak PS in southern China.
