In order to meet the requirements of mechanized sowing and improve the quality of seeds, the effects of different hybrid seed production densities on quality and vigor of Liaodan 565 seed were studied. [Method] Using Liaodan 565 as test material, setting four hybrid seed production densities 60 000, 67 500, 75 000, 82 500 plants/hm2,agronomic characters and seed vigor under different hybrid seed production densities were studied. [Result] Under 75 000 plants/plant height and stem diameter were higher than other treatments, the yield was the highest under 82 500 plants/hm2, seed vigor was the best under 67 500 plants/hm2. [Conclusion] In order to get better vigor seeds, hybrid seed production density was 67 500 plants/hm2 in Liaoning.
