Abstract

Introduction: The cytoplasmically inherited yellow foliar mutant, cyt-YJ, is the third uniparentally inherited mutant reported for soybeans (Shoemaker et al., 1985). The remaining two maternally inherited mutants are cyt-Y2, also a yellow foliar mutant (Palmer and Mascia, 1980), and cyt-Gl, a green cotyledon mutant (Terao, 1918). cyt-YJ is unique in the respect that it is near-lethal under normal light conditions and lethal under elevated photosynthetic photon flux densities, i.e., 600 to 2,100 microeinsteins m-2, respectively.
