Abstract:

To develop a new foxtail millet variety with high yield, multi-resistance, excellent quality, and wide adaptability, the Chifeng Academy of Agricultural and Animal Sciences bred ‘Jinmiao K4’ through methods of sexual hybridization and systematic selection, using the F₃ generation of ‘Chigu 10’ × ‘Huangjingu’ as the female parent and ‘Jinmiao K1’ as the male parent. This variety has a growth period of 120 d, plant height of 110.6 cm, and total starch content of 82.05%. It is characterized by high and stable yield, superior quality, herbicide resistance, comprehensive stress resistance, broad adaptability, and high suitability for mechanized harvesting. In the 2019-2020 regional trials, the average yield of ‘Jinmiao K4’ was 6077.4 kg/hm². In the 2020 production trial, its average yield reached 6136.4 kg/hm², which was 10.0% higher than that of the control variety ‘Huangjingu’, with a 100% yield-increasing point rate. It was awarded the National First-Class Quality Millet certification in 2021. In 2022, it was granted the national registration for non-main crops (GPD Foxtail Millet (2022)150085), and in 2024-2025, it was recognized as a leading variety in Chifeng City. The successful breeding of ‘Jinmiao K4’ has accelerated the replacement of old cultivars in major foxtail millet production regions, demonstrating broad prospects for application.

Key words: foxtail millet, 'Jinmiao K4', high yield, superior quality, herbicide resistance, breeding, cultivation, adaptability
