Abstract

Zhongzu 53, which is an early-season indica rice variety with high yield, was bred by China National Rice Research Institute and was approved by the Zhejiang Crop Variety Approval Committee in 2020. It is suitable for planting in Zhejiang Province and similar ecological regions as it has the characteristics of early maturity, moderate plant architecture, high tillering ability, large panicle with high grain number, and high yielding potentials. The average yield of Zhongzu 53 reached 10.26 t/hm2 and 9.90 t/hm2 in the large-scale demonstration of super rice in 2021 and 2022, respectively. It was subsequently identified as a new super rice variety by the Ministry of Agriculture and Rural Affairs in 2023. Zhongzu 53 was introduced to Jiangshan County for planting in 2017. It has become the main variety in Jiangshan as its production area accounted for more than 38% in 2023 and its cumulative production area has exceeded 3 333.33 hm2 in 2023. This paper introduced the planting performance and summarized the key high-yielding cultivation techniques of Zhongzu 53 in Jiangshan County in the last few years, which provided guidance for further promoting the cultivation of Zhongzu 53 in Jiangshan and similar area.
