Abstract
Segregation for male sterility was observed in an F3 row from the cross of L67-533 (Clark-S, short internode) x SRF300 at Urbana, Illinois in 1971. The observed segregation was 63 fertile: 21 sterile (expected 63:21, 50 assuming sterility controlled by a single recessive gene). This hypothesis was confirmed in 1972, when, totaled over 49 segregating rows, the observed segregation was 1,551 fertile : 528 sterile plants (expected 1,559:520) .
