Abstract

Abstract:

To determine the relationship between the degree of anthracnose and damage, and to screen the germplasm resources of resistance to anthracnose of southwest glutinous red sorghum, so as to lay a material foundation for breeding resistance to anthracnose. Field spray inoculation was carried out by artificially cultured dominant strain ZG-FS-1 with strong virulence. After inoculation, the resistance level was determined according to disease classification standard. Compared with the uninoculated group, the loss rate of seed weight and germination were obtained. Among the 92 sorghum resources, 10 were highly resistant (HR), 10 were resistant (R), 5 were moderately resistant (MR), 20 were susceptible (S) and 47 were highly susceptible (HS).The average loss rate of spike grain weight of HR, R, MR, S and HS resources were 4.37%, 6.69%, 8.89%, 34.12% and 52.50%, respectively. The average loss rate of 1000-seed weight were 1.81%, 2.98%, 5.59%, 14.56%, 28.89%, and the average loss rate of germination rate were 0.97%, 5.40%, 5.76%, 11.11%, 20.46%, respectively. Sorghum anthracnose can not only greatly reduce the yield of sorghum, but also reduce the germination rate of sorghum seeds. The resistance to sorghum anthracnose could be accurately identified by artificial inoculation and the selected resistant resources could be used as breeding materials for resistance genetic improvement.

Key words: Sorghum, anthracnose, resistance identification, spike grain weight, 1000-seeds weight, germination rate
