A PARTIALLY MALE-STERILE MUTANT LINE OF SOYBEANS, GLYCINE-MAX (L) MERR - CHARACTERIZATION OF THE MSP PHENOTYPE VARIATION Academic Article

abstract

• Investigations of variable expression of msp partial male sterility in soybeans (Glycine max (L.) M err.) showed that higher temperatures promote male fertility in msp homozygotes and showed that infectious agents are not intrinsic to the sterility system. Exchange grafts failed to modify fertility levels of msp msp rootstocks, Msp Msp scions, and their self-progeny. Tests for soybean mosaic virus and tobacco ringspot virus were negative in partially male-sterile plants, in control fertile plants, and in self-progeny of grafted plants. Growth-chamber experiments and field observations manifested that male fertility of msp msp plants is higher in hot environments than in cooler ones. The unexpected aberrant ratios of fertile to partially male-sterile plants observed in 1977 (Stelly & Palmer, 1980) are explainable on the basis of msp temperature sensitivity. Our observations suggest that homogeneous msp msp populations may be increased in hot environments. 1980 H. Veenman En Zonen B.V.
