| Abstract: | Objective] The study aimed to improve the yield and quality of hybrid seed production and promote the popularization of Wandao No.153.Method]Four treatments with planting density of 1,2,3,4 seedling/holl were set up,and tillering dynamics,agriculture characters and germination rate were investigated.Result] effective panicle,grain number per spike and seed production were obviously increased under multiple seedlings planting in one holl.Conclusion] Considering all kinds of factors synthetically,the optimum planting density of Wandao No.153 for seed production was 2 seedling/holl. |
