Abstract
Background and aims – The mode of inheritance of the chloroplast genome is an important factor in studies dealing with population and evolutionary plant biology. In this paper, we aim to determine the chloroplast DNA (cpDNA) inheritance in Rhinanthus angustifolius. Methods – We studied the cpDNA inheritance using PCR-RFLP. One hundred sixty six offspring obtained from controlled crosses between individuals with two distinct chlorotypes were analysed. Key results – All the progeny exhibited the maternal chloroplast genome. The power analysis of the binomial distribution showed that the frequency of paternal transmission of the chloroplast, if any, should not exceed 1.81% (with 95% confidence). This work indicates that maternal inheritance of the chloroplast genome in Rhinanthus angustifolius is a reasonable assumption.
