Planting Performance and High-yield Cultivation Techniques of Hybrid Rice Yongyou 1540

Yongyou 1540 was a indicaclinous three-line hybrid rice variety through eurytopic indica-japonica hybridization which was cross-bred with Yongjing 15A and F7540 by Crop Research Institute of Ningbo Academy of Agricultural Sciences and Ningbo Seed Co., LTD. From 2016 to 2018, Yongyou 1540 was used as the model planting of machine-transplanted and mechanical-reaped regenerated rice in Jianyang District of Fujian Province. The field performance was green and beautiful growth, with moderate plant height, strong root system, upright boot leaves, good light absorption, mature live stalk, good yield and strong adaptability. The first season had high yield and the yield was 11.3-12.0 t·hm^-2, while the regeneration season had stable yield and the yield was above 6.0 t·hm^-2. Last, the yield performance, characteristics and high-yield and high-effective cultivation techniques of Yongyou 1540 being planted as the model planting of machine-transplanted and mechanical-reaped regenerated rice in Jianyang District of Nanping city were summarized.
