Abstract:

To further understand the production characteristics and applicable value of the wheat variety ‘Hemai 26’, its yielding ability, yielding stability and adaptability as well as resistibility and quality characteristic were analyzed with ‘Zhoumai 18’ as the contrast using the regional tests of wheat varieties in southern Huang-Huai Wheat Region consisted of institutions and enterprises during 2016-2018 and production tests in 2018-2019. The results showed that the yield of ‘Hemai 26’ increased by 4.5%, 11.53% and 5.28% respectively compared with that of ‘Zhoumai 18’ during 2016-2019, and reached a significant level. Coefficient of variation (CV) of ‘Hemai 26’ was slightly smaller, the high stability coefficient (HSC) was larger and adaptability was higher than that of ‘Zhoumai 18’. The average yield of each experimental variety showed linear regression with the average yield of ‘Hemai 26’ in different test sites, and the regression coefficient tended to 1. ‘Hemai 26’ has strong lodging resistance and general disease resistance. ‘Hemai 26’ has good grain uniformity, high grain bulk density and good quality. ‘Hemai 26’ has outstanding yielding ability, good yielding stability, wide adaptability and excellent quality, which has good promotion and utilization value in Southern Huang-Huai Wheat Region.

Key words: wheat, ‘Hemai 26’, ‘Zhoumai 18’, productivity, stability, adaptability, resistibility, quality traits
