Abstract:
A new soybean variety Zheng 1311，which was released by Henan Academy of Agricultural Sciences， was derived from the combination of Zheng 9805×Luo F20-3. The average yield of Henan Province regional test was 3 021.7 kg?ha-1，which was 13.7% higher than control variety Yudou 22 in 2017 and 2018.The production test average yield was 2 998.8 kg?ha-1，which was 15.9% higher than control variety Yudou 22 in 2018. The average yield of National Huanghuai central regional test was 3 297.0 kg?ha-1，which was 18.3% higher than control variety Handou 5 in 2017 and 2018.The production test average yield was 3 114.0 kg?ha-1，which was 23.2% higher than control variety Handou 5 in 2018. The average yield of National Huanghuai south regional test was 3 228.0 kg?ha-1，which was 18.0% higher than control variety Zhonghuang 13 in 2018 and 2019.The production test average yield was 3 025.5 kg?ha-1，which was 16.4% higher than control variety Zhonghuang 13 in 2019. It was approved by Henan Province and National Crop Variety Approval Committee， respectively， in 2019 and 2020. Zheng 1311 was a super high yield variety， which has created 8 yield firsts in 9 groups of regional trials and production trials in Henan Province， central and southern Huanghuai region of China.
