Last Updated: 2024/11/22, (1) Variety source: it is the Zhenshan 97A female parent of Chengdu Biology, Chinese Academy of Sciences, and is a new medium indica late maturing black rice combination made from black rice restorer line 3350 (Shaanxi Yangxian 1 black rice / Yunnan Rui 499). (2) characteristics: the whole growth period is 156.1 days, which is 5.3 days longer than that of Shanyou 63. The plant height is 109.9 cm, the tillering ability is strong, the growth is exuberant, the ear is flat with 166.8 grains, the seed setting rate is 76%, the 1000-grain weight is 26.1g, and the brown rice rate is 77%.

The main results are as follows: (1) Variety source: it is a new medium indica late maturing black rice combination derived from black rice restorer line 3350 (Shaanxi Yangxian 1 black rice / Yunnan Rui 499) from Zhenshan 97A female parent of Chengdu Biology of Chinese Academy of Sciences.

(2) characteristics: the whole growth period is 156.1 days, which is 5.3 days longer than that of Shanyou 63. Plant height 109.9 cm, strong tillering ability, vigorous growth, 166.8 grains per ear, seed setting rate 76%, 1000-grain weight 26.1g, brown rice rate 77.8%, brown rice purplish black, middle and high appearance quality, rice blast resistance identification, leaf blast grade 6-8, neck blast grade 7.

(3) yield performance: in the 1995 provincial regional trial, the average yield per mu was 475.0 kg at 18 points, which was reduced by 15.0% compared with Shanyou 63. In the production test in 1996, the average yield per mu in 5 pilot projects was 506.4 kg, which was 13.05% lower than that of Youshan 63.

(4) Heiyou 1 is the first black rice hybrid rice bred in the province, and its yield is more than 100 kg per mu than that of conventional black rice, which has better economic benefits and prospects for development and utilization.
