Abstract:

This study analyzed the yield performance and composition factors of new elite wheat variety ‘Ruihuamai 520’ with high yield and good quality, aiming to provide a basis for its popularization. The high and stable yield of wheat variety ‘Ruihuamai 520’ was analyzed by using the national and provincial intermediate tests and multi-point data of large-scale application. The results showed that the yield point rate of ‘Ruihuamai 520’ reached 100% in regional trials of Jiangsu Province, the yield increasing point rate was 88.2% in the two-year test in the national regional trial; the mean variation coefficient was 7.16% and 12.2%, respectively, ranking the first and the seventh of the tested varieties. The value of variation coefficient was 494.97 and 618.97, respectively, ranking the second and the third of the tested varieties. The average number ears, the number of grains per ear and the weight of 1000 grains of the variety ‘Ruihuamai 520’ were (633.0 ± 64.5)×10 4/hm2, 31.1 ± 4.5 and 40.2 ± 3.0 g, respectively, indicating that the three factors of yield were coordinated and stable. The experiments show that wheat variety ‘Ruihuamai 520’ has high and stable yield, and good resistance to major diseases and natural disasters in southern Huanghuai area.

Key words: wheat, Ruihuamai520, high yield, stable yield, disease resistance
