PREVIOUS work by the authors demonstrated that alfalfa pollen tubes could be successfully cultured in vitro. It was shown that the average pollen tube length in vitro varied greatly among diploid alfalfa clones. If similar variations in pollen tube growth were present in situ, there could be important consequences in alfalfa seed production. Differential pollen tube lengths could result in nonrandom fertilization due to the competitive differences of long and short pollen tubes. Variations in seed yield could also result from pollinations among plants differing in pollen tube length.
