We conducted tests in the summers of 1981 and 1982 to determine seed set on the maturity group 3 cultivar 'Williams' and its ms2 ms2 male-sterile isoline. In these studies, Williams plants segregating for male sterility and the maturity group 5 cultivar, 'Forrest', were grown outdoors in pots at three isolated sites. We identified sterile and fertile plants immediately at flowering using standard pollen germination techniques.
