We end‐labeled Hin fI restriction digests of a PCR‐amplified plastid encoded gene, the large subunit of ribulose bisphosphate carboxylase, to investigate patterns of cpDNA inheritance in Turnera ulmifolia . A total of 70 progeny from crosses among plants taken from ten populations revealed varying patterns of inheritance. A majority of progeny inherited the paternal cpDNA (64%), while 19% exhibited maternal and 17% biparental inheritance. Eight variegated progeny showed biparental inheritance and were analyzed in greater detail. We extracted and analyzed the cpDNA content of light‐ vs. dark‐green leaf sectors from these plants. The results showed that vegetative segregation of cpDNA had occurred for seven of the eight plants.
