RESULTS OF INTERGENERIC FRAGARIA AND POTENTILLA SPP. CROSSES
From among 119 matroclinous plants, 77 produced relatively highly viable seeds in open pollination, 33 gave seeds of low viability and 8 produce completely sterile seeds. Preliminary examination of the progeny of matroclinous plants seems to indicate that it is possible to obtain a next fertile generation (MR2) which, under conditions of controlled pollination, would preserve its initial ploidy. Under the influence of open pollination the matroclinous plants exhibit a tendency to a return to higher ploidy.
