SUMMARY Seed lots of F 1 hybrids of Brassica oleracea are unmarketable if they contain too many sibs. The modified sequential probability ratio test (SPRT) proposed by Whitehead (1981) can be used to determine whether a hybrid seed lot meets specified quality standards for sib content and to estimate the actual proportion of sibs. It is more economical in testing than a single‐sample procedure of equal accuracy and is particularly suited for use with electrophoretic methods of sib recognition. A computer program has been written to produce control charts, for a range of test standards, for direct plotting of results.
