Summary

B chromosomes were found in a triploid which had no seedset in selfing, or in a cross with a highly fertile tetraploid (3nB×4n). From the reciprocal cross (4n×3nB) 8 progeny plants were obtained which contained B chromosomes. These plants had very low seedset and yielded only 24 eutetraploids (4n=28) in the next generation. All except one of these plants had B chromosomes. The 4nB plants showed high frequencies of A chromosome chiasmata and multivalents, including complex configurations.
