Abstract

Incidence of bacterial blight of soybeans was observed from 1953 to 1959. During this period the disease was observed in 25 to 72 percent of the fields examined. A search was made for an improved source of blight resistance. A soybean introduction, P.I. 68708 was resistant to blight under natural conditions and when inoculated. It was also resistant to brown spot but was susceptible to race 8 of Peronospora manshurica as well as to Phytophthora rot. Yield, date of maturity, seed size, seed quality, and lodging resistance of the introduction were comparable to the same characters of the variety Blackhawk.
