Abstract

General characters associated with the soybean male-sterile msl gene have been described in a previous study (Chen et al., 1985). Among the four spontaneous and independent msl source populations (Palmer et al., 1978), the Urbana male-sterile (msl-Urbana) line was reported to have 1) higher female fertility (Boerma and Cooper, 1978), 2) lower percentage of ovule abortion (Kennell and Horner, 1985), and 3) higher percentage of pollen-tube germination in male-sterile anthers (Chen et al., 1986). However, no report has men-tioned whether gynoecia of male-sterile plants would have the same receptivity as those of male-fertile plants, when fertile pollen was applied to the stigma of male-sterile plants.
