Abstract:

Thirty domestic and international oat cultivars were analyzed for their essential nutrients, amino acids, and mineral contents. The technique of grey correlation degree analysis was used to thoroughly assess their nutritional composition. The findings demonstrated that compositions of some cultivars differed significantly, indicating that oats possessed a high degree of genetic variation. The highest crude protein content was found in Dingyou 1 (23.76%), the highest crude starch content was found in Bayou 6 (73.16%), and the highest crude fat content was found in Baiyan 8 (10.03%). Among the functional nutrition indexes, the contents of total flavonoids ranged from 420.08 (Jinyan 9) to 3395.12mg/kg(Bayou 9). Total phenol content ranged from 1516.02 (Bayou 5) to 5463.71 mg/kg (ITAO-63). Phytic acid content ranged from 8.74 (Shadow) to 25.91 mg/kg (Keyan 1). Compared with other amino acids, the contents of Glu, Leu, Asp, Arg were higher, while the contents of Cys and Met were lower. The highest content of total amino acid was ITAO-63 (16.29%), the lowest was Bayou 1 (11.57%). Among them, the essential amino acid of the materials from Italy was generally higher, and the content of ITAO-27 (3.94%) was the highest. The mineral elements of different resources of oats had particularly rich genetic diversity. The order of major elements content was K > Mg > Ca > Na, while the order of trace elements was Mn > Zn > Fe > Cu > Ni > Se. Ultimately, the equal-weight correlation degree and weighted correlation degree research revealed that Bayou 8, ITAO-63, and Baiyan 6 were the top three comprehensive nutritional attributes among 30 oat types. These cultivars can serve as the foundation for superior oat variety breeding or as specialty cultivars for the creation and application of beneficial foods.

Key words: Oat, Nutrient composition, Amino acid, Mineral elements, Grey correlation analysis
