Abstract
Abstract Self progenies obtained from bud pollination or from self pollination following high temperature treatment of 7 self incompatible (SI) Petunia hybrida Vilm. plants representing the I1, I4, I6, and I7 generations were tested for SI in both summer and winter greenhouse environments. Five exhibited increased self seed set (pseudo-self compatibility, PSC) after winter pollinations, 1 was more PSC after summer pollinations, and 1 set no self seed in either pollination environment. Comparison of sibling progenies within a line at the I8 generation and differences in PSC between lines at the I7 and I8 generations indicate that inbreeding has not destroyed the possibility of recovering SI.
