Abstract: In order to promote the promotion of a new waxy corn variety with high quality, this paper briefly introduced the breeding process, variety characteristics, yield performance and cultivation points of a new waxy corn variety Hanian 5. Hanian 5 was bred in 2015 by the maize research office of the Harbin Academy of Agricultural Sciences with self-selected yellow waxy maize inbred line HA4146 as female parent and self-selected yellow waxy maize inbred line HA4139 as male parent. During 2017-2018, the average yield was 15 238.2 kg·ha^-1, which was 4.3% higher than that of the control variety Jinuo 262. During 2019-2020, the average yield was 15 856.6 kg·ha^-1, which was 6.4% higher than that of the control variety Jinuo 262. In 2022, it was approved by the Heilongjiang Variety Approval Committee, with the approval number Heishenyu 20220036. It is yellow in appearance, good quality, high viscosity, thin skin, no residue, good palatability and high yield, and the eating quality is 89 points. In the adaptation area, the feeding period is about 85 days, and the growth days from emergence to maturity is about 110 days, and the variety is suitable for planting in ≥10 ℃ active accumulated temperature of 2 300 ℃.
