Inheritance of the White Seed Character in Alfalfa1
- Robert K. Oldemeyer2
White seed in alfalfa is conditioned by a duplicate set of homozygous recessive genes for colorless and one dominant color inhibitor gene. This gene complex also inhibits anthocyanin production throughout the plant. The distribution of the offspring of a white-seeded hybrid having pure alfalfa parentage was interpreted as resulting from selective pairing of chromosomes, and that of a white-seeded hybrid, having as one parent an artificially induced autotetraploid from diploid Medicago falcata, as being the result of random chromosome pairing. These results are taken as evidence that alfalfa is of autotetraploid origin, and has evolved into a functional diploid.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
