Abstract: | Tianlongyou 1340 is a new three line hybrid rice combination, bred by Sichuan Xike Seed Co. Ltd. and Henan Province Xinyang Academy of Agricultural Sciences, derived from Tianlong 13A, a CMS line as female parent, and Tianlonghui 140, a high biomass and high combining ability restorer line. The average yield of the regional test in 2012-2013 was 585.5 kg/667 m 2, increased by 6.9%, and had extremely significant difference with the control. The average yield of the production test in 2014 was 608.4 kg/667 m2, increased by 7.0%, the yields of all the test points were increased. It was approved by Henan Provincial Crop Variety Approval Committee in 2015. |
