Abstract:

It aims to evaluate the storage tolerance of 20 popular wheat varieties from the Huang-Huai wheat region under natural aging conditions and classify them,thereby providing a theoretical basis for the breeding and selection of storage-tolerant wheat varieties.The experiment involved natural aging treatments of 12 and 24 months,with seeds harvested 3 months prior serving as the control.Measurements included seed vigor,seed coat characteristics(color and cell membrane integrity),and physiological and biochemical indicators(soluble sugar,gluten protein,starch content,antioxidant enzyme activity,and malondialdehyde content).The results indicated that as aging time increased,seed vigor of all varieties significantly declined.Germination rate and germination potential decreased by 2.17-10.79 percentage points and 2.80-23.39 percentage points,respectively,after 12 months,and further declined by 15.95-25.88 percentage points and 14.93-41.44 percentage points after 24 months.The hue,saturation,and intensity of seed coat color decreased,while electrical conductivity increased,indicating gradual damage to the seed coat cell membrane.Among the physiological and biochemical indicators,except for malondialdehyde,soluble sugar,protein,starch content,and antioxidant enzyme activity all showed a declining trend,with greater declines observed after 24 months compared to 12 months.Total starch content exhibited the most significant decrease,declining by 6.43-32.13 percentage points and 21.02-44.95 percentage points after 12 and 24 months,respectively.Based on indicators such as germination rate,seed coat color,electrical conductivity,soluble sugar,and antioxidant enzyme activity,the 20 wheat varieties were classified into storage-tolerant,moderately storage-tolerant,and non-storage-tolerant types.Among them,Annong 0711,Luohan 19,and Xinmai 26 demonstrated strong storage tolerance.The findings provide parental materials,evaluation criteria,and theoretical references for the breeding of storage-tolerant wheat varieties.
