Abstract:

Zhuoliangyou 1126 is a new strong heterosis hybrid rice combination bred by Hunan Agricultural University using the small grain male sterile line Zhuo 201S and the large grain restorer line R1126. It has good plant and leaf morphology, straight sword leaves, relatively low panicle layer, well-developed root system, large panicles and more grains, high seed setting rate, good quality, excellent lodging resistance and high yield potential. At the same time, the small grain male sterile line of this combination can undergo light and simple mechanized seed production, achieving full mechanization of hybrid rice seed production, reducing seed costs, promoting the transformation of rice production methods. In 2023, the super-high yield cultivation demonstration of Zhouliangyou 1126 was carried out in Mengzi City, Yunnan Province, and the average yield is 17.79 t/hm2. This article elaborated on the super-high yielding cultivation techniques of Zhuoliangyou 1126 with yield of 17.79 t/hm2, and proposed key measures to achieve high yield.

Key words: hybrid rice, Zhuoliangyou 1126, high-yielding cultivation techniques

摘要：

卓两优1126是湖南杂交水稻研究中心和湖南农业大学用小粒不育系卓201S与大粒恢复系R1126选配而成的强优势新组合。该组合株叶形态好，剑叶挺直，穗层相对较低，根系发达，穗大粒多，结实率高，稻米品质好，具有优异的抗倒伏能力和较大的高产潜力。同时，该组合的小粒型不育系可进行轻简机械化制种，实现杂交水稻种子生产全程机械化，降低种子成本，促进水稻生产方式转型。2023年卓两优1126在云南省蒙自市进行百亩超高产攻关示范，平均单产达17.79 t/hm2。本文详细阐述了卓两优1126百亩片单产17.79 t/hm2超高产栽培技术，并提出栽培种植过程中获取高产的关键措施。
