Soybean Genetics Newsletter


A natural epiphytotic of soybean mosaic virus (SMV) occurred at the Harrow Station in 1976. The disease, which was noted in early July, reduced plant growth. Advanced lines from 'Corsoy' x 'Chippewa 64' were being tested in the field in relation to their flavonol glycoside classification. Plants were rated for severity of leaf symptoms and seeds were rated for mottling.
