Abstract:

In order to make the large of barley germplasm which domestic bred and introduced to be used reasonable, 41 domestic and foreign two-rowed malting barley had been classified based on grey relation grade analysis of agronomic character. The results showed that, for the varieties which composited character performed well: such as number 2, number 8, number14, after introducing experiment could attend area experiment directly; number 1, number 3, number 12, number 16, number 24, number 38, number 40, number 41 could be used as important parents. The individual plant height of number 1, number 3, number 16 and number 40 varieties could be improved, and the protein contents of number 38, number 41 could also be improved. Number 21, number 22, number 25, number 27, number 31 could be treated as excellent parents for seed selecting. Number 10, number 17 and number 23 which comprehensive expression was not very well could be eliminated courageously, in order to decrease breeding load and cut down cost.
