Abstract
Possibility to receive hybrids between distantly related species is restricted by reproduction isolation barriers. To overcome such barriers different methods are explored. Our attempts to cross lilies from group AH (Asiatic hybrids) with distantly related species L. candidum for a long time was unsuccessful, until AH female was pollinated by pollen of L. candidum L. mixed with pollen of other incompatible species L. regale Wils. and L. monadelphum Bieb. To identify origin of such progeny and to screen offspring of L. candidum L. inheritance of male characteristic SOD (superoxid dismutase) isozymes were choosed. Progeny inherited SOD isoforms from L. candidum L. in juvenile stage posesssed broad leaves – the trait characteristic for L. candidum L. Among 30 progeny l6 were selected as distantly related interspecific hybrids derived from AH × L. candidum L.
