优质抗病三系杂交稻新品种忠优511的选育与应用
Breeding and Application of New High-quality and Disease-resistant Three-line Hybrid Rice Variety Zhongyou 511
摘要
Abstract
Zhongyou 511,an indica three-line hybrid late rice variety,is a new high-quality and disease-resistant rice variety developed by crossing Zhongxiang A as female parent and Quanhui 511 as male parent.In 2021-2022,this variety participated in the middle-maturity group trial of late rice conducted by the Xiamen University Seed Industry Innovation Science-Enterprise Consortium,the average growth period of Zhongyou 511 was 121.7 d,which was 0.9 days longer than that of the control Tianyouhuazhan,and the average yield was 8 793.0 kg·hm-2,which was 1.8%higher than that of the control.In production trials,the average yield of Zhongyou 511 was 8 716.5 kg·hm-2,which was 3.7%higher than that of the control Tianyouhuazhan.Zhongyou 511 had the characteristics of high quality,moderate resistance to rice blast,stable yield and wide adaptability.It was approved by Fujian Crop Variety Approval Committee in 2023.In this paper,the breeding process and variety characteristics of Zhongyou 511 were introduced,and the key points of seed production and cultivation techniques were summarized,so as to provide reference for its further promotion and subsequent breeding improvement.关键词
