Abstract: To fully understand the excellent characteristics of Zhengnonggu 09-6, according to the yield results of the regional test of millet varieties in Henan province from 2014 to 2015, the high yield, stable yield and adaptability of Zhengnonggu 09-6 were analyzed by using various analysis methods such as variance, standard deviation, coefficient of variation, high stability coefficient and regression coefficient. The results showed that the average yield of Zhengnonggu 09-6 was 5 961.6 kg/hm~2 in the 2-year regional trial, ranking the 2 nd and 4 th place respectively, with good yield. This variety had high stability coefficient, small variation coefficient and small regression coefficient, and had good yield stability and wide adaptability. At the same time, the test and detection results showed that the strain had higher stress resistance than the control. All the quality indexes were higher than the national standard of grade two high quality rice. Combined with the promotion and application from 2018 to 2019, this variety had excellent characteristics of good quality, high yield, stable yield, strong resistance to stress, and wide adaptability, which was suitable for promotion and planting in summer valley areas of Henan province.
