Abstract
Individual quantitative variation in rDNA content within three species of the Cucurbitaceae family has been studied by rRNA/DNA filter hybridization experiments. The results showed a 2.3-fold range of variation in the number of ribosomal cistrons per diploid cell in an Ecballium elaterium natural population. This range of variation is compared with the smaller range observed in three Cucumis sativus and in two Cucurbita pepo varieties obtained as F1 hybrids between pure lines.Entities:
