染色体数目大的多倍体植物一定起源于染色体短的植物，而染色体长、数目大的多倍体植物通常是异源多倍体。从染色体短、数目少的植物中获得同源四倍体可能更适合于植物育种工作。提出的数据支持这样的理论，即从具有长染色体的植物获得的同源多倍体应具有比从具有短染色体的植物获得的同源多倍体低的育性，只要在任一情况下植物具有相同或近似的育性。相同的染色体数目。
Polyploid plants with large chromosome numbers must have originated from plants with short chromosomes; and those having long chromosomes and large chromosome numbers are usually allopolyploids. Autotetraploids pro-duced from plants with short chromosomes and with small chromosome numbers will probably be more suitable for plant-breeding work. The data presented support the theory that autopolyploids obtained from plants with long chromosomes should have lower fertility than those obtained from plants with short chromosomes, provided that in either case the plants have the same or approx. the same chromosome numbers.
