Studies of chlorophyll deficient soybeans have shown that normal development of chlorophyll is controlled by several genes . The recent review by Bernard and Weiss (1973) summarizes information about the known published chlorophyll defi cient lines . A number of soybean lines exhibiting chlorophyll deficiencies which have not been studied genetically are included in the genetic type collection maintained at the U.S. Regional Soybean Laboratory.
