Somaclonal Variant

Rose-scented geranium ( Pelargonium spp.), which is highly valued for its essential oil, is exclusively propagated vegetatively. Hence no genetic improvement work is possible through conventional breeding. Somaclonal variation was generated with and without in vitro mutagenesis using N-nitroso- N-methyl urea (NMU) in an Indian cultivar ‘Bourbon’, and a clone ‘Narmada’. A somaclonal variant (N75) with a moderately high content of isomenthone in its essential oil was isolated from somaclones generated after treatment of internodal explants of clone, ‘Narmada’ with 0.25 mM NMU for 1 h. The contents of isomenthone in its essential oil were 26% and 35%, respectively, in SC2/VM2 and SC3/VM3 generations (second and third vegetative generations, respectively, after in vitro mutagen treatment) as compared with 0.7% and 0.3%, respectively, in the parental clone, ‘Narmada’. The contents of alcohols and their esters (linalool, citronellol, geraniol, citronellyl formate and geranyl formate) in the essential oil of N75 in SC2/VM2 and SC3/VM3 generations were 49% and 35%, respectively, as compared with 69% and 63%, respectively, in the parental clone, ‘Narmada’. This is the first report on a chemovariant of rose-scented geranium with a moderately high content of isomenthone. All earlier reported isomenthone-rich variants of rose-scented geranium had quite high contents of isomenthone (64-71%) in their essential oils. The probable modes of origin of this somaclonal variant, its parental clone ‘Narmada’ (with very low content of isomenthone) and four earlier reported isomenthone-rich variants of Indian cultivars of geranium are discussed.

Detailed analysis of the seeds of 128 individual plants of an Indian mustard accession, PI 183117, grown at a field site with adequate soil sulfur, revealed a wide variation in both the composition and total concentrations of seed glucosinolates. An apparent somaclonal variant of the same accession is also reported. Selection of seeds from this variant resulted in the isolation of plants with significantly lower seed glucosinolate levels and a greatly reduced variability in both content and proportions of the major seed glucosinolates, compared with the parental line. Averaged over the field experiment, and 2 glasshouse experiments (the second with 2 soil sulfur levels), the reduction in total glucosinolate concentration was 22%. Neither the effect of additional sulfur, nor its interaction with the test populations, was significant. Assuming that the variation in total seed glucosinolate concentration between plants within the selection was entirely environmental, the lower limit of the broad sense heritability in the original accession was estimated as 29.5%. Additional genetic variation appears to be necessary to reduce the seed glucosinolate content to the maximum level specified under the 'Canola' standard for rapeseed.
