Abstract:

In order to select new wheat varieties suitable for planting in southern Shandong Province, 9 traits of 19 wheat varieties were evaluated by DTOPSIS method based on entropy weight. The results showed that: the weight of each index from low to high was growth period < yield < bulk density < plant height < effective panicle < basic seedling < 1000-grain weight < heading rate < number of grains per panicle. The Ci values of 6 varieties were greater than 0.5, including ‘Shannong HH126’ (0.9221), ‘DK171’ (0.8680), ‘Hemai 179’ (0.8515), ‘Feida No. 6’ (0.7196), ‘Jinlai 36’ (0.6967), and ‘Yannong 301’ (0.5232). Therefore, these six varieties have good comprehensive characters and are suitable for planting and promoting in southern Shandong Province.
