Abstract:

Fengza 56 is a liquor-making sorghum hybrid carefully bred by Gaoke Crop Breeding Research Institute of Gongzhuling National Science and Technology Park(Jilin Zhuangyi Seed Industry Co., Ltd.). It was developed by crossing the self-selected sterile line ZY4208A(female) and the self-selected restorer line R2054-4(male) in 2017. This hybrid demonstrates strong drought tolerance, excellent comprehensive resistance, wide adaptability, and stable yield. It was officially registered as a national crop variety in 2022. This paper systematically introduces the parental sources and breeding procedure of Fengza 56, analyzes its main characteristics and yield performance, and summarizes the key techniques of cultivation, propagation and seed production.
