Jaeger’s Seedlings. About forty years ago Hermann Jaeger, of Neosho, Missouri, became interested in the horticultural possibilities of the wild grapes of his neighborhood. He corresponded with Frederick Muench, of Marthasville, who encouraged him in his efforts. Beside selecting various vines from the woods he made crosses of species. His object was to secure more vigorous, productive and disease-resistant sorts than any of our standard varieties. He was particularly impressed with the Lincecumii or so-called Summer grapes of his section. His selections of this species are notable for their extreme vigor but many of them are susceptible to fungi and as they are all self-sterile they are uncertain bearers when removed from the wild male vines. His most promising seedlings are as follows:
No. 9. Productive; subject to black-rot; cluster large; berry below medium; juicy, sweet; good.
No. 12. Cluster and berry medium; sweet.
