国审小麦新品种平麦16的选育及产量结构分析OACSTPCD

Pingmai 16 was crossed with Pingmai 189 as female parent and Zhoumai 18 as male parent.It was systematically selected and bred for 15 years and was approved by National crop Variety approval Committee in 2023(National examina-tion and approval of Maize 20230102).In The average yield of Pingmai 16 in the joint regional trial of wheat trial in the southern part of Huang-Huai River in the new century in 2017-2018 and 2018-2019 was 6 903.0 kg/hm2 and 8 723.2 kg/hm2,respectively,while which was 8 409.0 kg/hm2 in production test in 2020-2021.which was 3.32%,5.44%and 8.00%higher than that of the control(CK)Zhoumai 18.The results of yield structure analysis of this variety showed that effective panicle,1000-grain quality and the number of grains per spike were positively correlated with yield,and the direct positive correlation coefficient decreased in turn.According to the comprehensive analysis,Pingmai 16 is a medium gluten variety with high and stable yield,strong lodging resistance,strong cold resistance and coordination of three factors of yield,which has good value of popularization and application.
