Abstract:

In order to comprehensively understand the production characteristics of the national approved wheat variety ‘Weimai 9’, the summary data of the regional test and production test of Shaanxi Province from year 2016 to 2018, the regional trial production test of the dry and thin group in the national Huanghuai winter wheat area from year 2018 to 2020, as well as the production test results of the demonstration field of ‘Weimai 9’ in 2021 and 2022 were used. The productivity, stability and adaptability of ‘Weimai 9’ and ‘Jinmai 47’ (CK) were compared by the indicators of yield, coefficient of variation (CV), high stability coefficient (HSC) and adaptability, and the comprehensive resistance of cold resistance, drought resistance, hot resistance and disease resistance were analyzed to clarify the variety characteristics of ‘Weimai 9’. The results showed that the yield of ‘Weimai 9’ was more than 3 % higher than that of ‘Jinmai 47’ in the regional test and production test of 6 years. The CV of yield was slightly lower than that of the control ‘Jinmai 47’, and the HSC was lower than that of ‘Jinmai 47’. The ability to resist dry and hot wind was strong, the yellowing was good, and the quality was also greatly improved compared with ‘Jinmai 47’. ‘Weimai 9’ has outstanding yield, well stability, wide adaptability, excellent quality and well combined resistance, which is suitable for further promotion and utilization in the dry and thin land of Huanghuai area.

Key words: wheat, ‘Weimai 9’, productivity, stability, adaptability
