High Yield Cultivation Techniques for the New Hybrid Rice Combination Zhuoliangyou 1126 with a Yield of 17.79 t/hm2
s: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.
