Abstract:

This paper introduced the breeding process, main characteristics and the cultivation technology of silage maize variety ‘Zhongyu 335’. The variety was selected and bred by Sichuan Jialing Crop Variety Research Center, and it is a high-yield, high-quality, widely adapted and dual-purpose new maize variety, crossed by self-selected line ‘2YH1-3’ (female parent) and self-selected line ‘SH1070’ (male parent), and was certificated by Sichuan Province, Guizhou Province, Yunnan Province and Hubei Province in 2009-2012. In 2018-2019, it passed the validation of special silage maize by the Nation and the Beijing Municipality, and was registered for introduction in eight provinces and autonomous regions, including Shannxi, Shanxi, Hebei, Tianjin, Liaoning, Jilin, Inner Mongolia, and Chongqing. This variety has the characteristics of high yield, excellent quality, strong comprehensive resistance, adaptability, and low seed production cost. According to the specific condition of each production place, taking complementary cultivation techniques as timely sowing, reasonable dense planting, scientific fertilization, strengthening field management and pest control, etc., the variety’s potential can be fully exerted and the high yield can be easily obtained.
