[Productivity of autotetraploids and frequency of aneuploidy in reproduction in Haplopappus gracilis L].
Comparative studies of productivity of autotetraploid plants H. gracilis L. after selection for high productivity, without selection for high productivity and aneuploidity, and after selection for low productivity have been done. The results show considerable effectiveness of selection for productivity. Presence of hyperaneuploid forms in the population is a major cause of the decreasing of autotetraploid productivity.
