Abstract
The role of mutant plastom, nucleus, and nucleus-plastom interaction i n manifestation of the heterosis effect for morphophysiological traits was studied in sunflower hybrids. A high level and frequency of heter osis were mainly determined by mutation differences in plastoms of the parental lines crossed. In a set of hybrids, nuclear genes and intera ction between nucleus and plastom played the main role in development of heterosis.
