Studies were made to determine the amounts of crosspollination when a white-flowered clone was grown alone and with purple-flowered clones in cages using several honeybee management practices. Progeny from seed of the white-flowered clone were classified for flower color. The 2-year average percent crossing was 57 when a nucleus colony was used and 72 when bees were intermittently confined. However, 10% crossing was found in the cage which had only the white-flowered clone. The 72% should probably be adjusted to 62% since 10% contamination may have occurred where bees were intermittently confined.
