Glory lily (Gloriosa superba L.) is one of the major medicinal plants of India cultivated for its seeds which are exported to developed countries for pharmaceutical use. Identifying germplasm is an important component for efficient and effective management of plant genetic resources. Variability for qualitative and quantitative traits was investigated in 18 genotypes of G. superba collected from different regions of Tamil Nadu and Andhra Pradesh. For qualitative traits, these genotypes were subjected to diversity analysis based on NBPGR descriptors. Fourteen qualitative and twenty quantitative traits of G. superba were evaluated to assess morphological variations among the genotypes collected. In qualitative traits, a large number of genotypes of the 18 clustered together, at 77% similarity in two clusters. Dendrogram constructed on the basis of twenty quantitative traits for the same set of genotypes did not reveal any clear pattern in grouping, and the genotypes were grouped into seven different clusters. Cluster analysis based on qualitative and quantitative traits revealed a different group of genotypes for each of the data-set. This clearly indicated that less variation existed between genotypes with respect to morphological traits. These easily observable morphological traits are useful tools for preliminary evaluation, because, they offer a fast and reliable approach for assessing extent of diversity in G. superba genotypes.Keywords

Phyllanthus amarus Schum. and Thonn (Euphorbiaceae) is recognized commonly as 'Bhumyamlaki' in the Indian system of medicine and has been traditionally used for treating a variety of ailments, including hepatic disorders. Anti-hepatic viral compounds such as phyllanthin and hypophyllanthin were evaluated in different types of in vitro cultures of Phyllanthus amarus by High Performance Liquid Chromatography (HPLC). Among the cultures, in vitro plantlets regenerating from the nodal segment recorded higher amounts of phyllanthin and hypophyllanthin.Keywords

Turmeric (Curcuma longa L.) is an ancient spice, native of India and South East Asia used from antiquity as spice and a dye. It is commonly propagated through rhizomes. The availability of disease free quality planting material is scarce during the cropping season (June – September). An experiment was conducted to study the performance of in vitro derived turmeric plants with conventional rhizome under field condition. The results indicated that the tissue culture plants showed better performance over the conventional rhizome planting. Tissue culture plants grew vigorously and taller than conventional type. The highest yield potential was observed in tissue cultureplants (40.83 tons/ha) as compared to the conventional rhizome planting (30.14 tons/ha). The rhizome rot incidence was lower (3.87%) in tissue culture plants than rhizome-derived plants (25.58%). However, the agronomic traits observed during the present study in tissue culture plants are stable and rhizome harvested from tissue culture plants can be used as disease free planting materials for further planting.Keywords
