Summary, etc.	A comparative evaluation of the morphological, histological and biochemical <br/>features of various Adhatoda accessions collected from different parts of Kerala was <br/>carried out in the Department of Plantation Crops and Spices, College of <br/>Horticulture, Vellanikkara during 1998-2000 for characterizing the germplasm <br/>accesions and to ascertain their species identity. <br/>The 52 accessions after evaluating for their morphological characters were <br/>classified into three clusters, which represented A.zeylanica (7types), A.beddomei <br/>(20) and intermediate types (25). Key characters which served for distinguishing <br/>between the two species were identified as plant habit, leaf size and shape, stomatal <br/>distribution, streaks on corolla and pubescence of ovary. A.zeylanica types were <br/>taller in habit with more number of branches, long petiole, broadly elliptic lanceolate <br/>hypo stomatic leaves and white flowers with purplish streaks inside and large <br/>pubescent ovary. A.beddomei types were small with lesser number of branches, short <br/>petiole, narrowly elliptic lanceolate amphistomatic leaves, with white flowers <br/>without purplish streaks inside and small glabrous ovary. Intermediate types showed <br/>both the leaf and floral types emphasizing the possible occurrence of natural hybrids <br/>in the genus. The variation in the elution pattern of phenols and terpenoids typical to <br/>the species makes them to be effectively utilized in the biochemical characterization <br/>of the species. A.zeylanica types showed a higher alkaloid content (0.66%) <br/>compared to intermediate types (0.38-0.55%) and A.beddomei (0.27-0.32%). <br/>Isozyme and enzyme studies also showed variation between accessions. However, <br/>further trials involving more enzyme systems is necessary for characterization of <br/>species. <br/>High heritability (broad sense) accompanied with high genetic advance for leaf <br/>area and petiole length indicates that most likely the heritability is due to additive <br/>gene effects and selection based on such traits may be effective. The growth was <br/>found progressive upto 12 MAP when it yielded more fresh and dry weights of whole <br/>plant, leaf, stem and root compared to 6 MAP. A higher alkaloid content as well as <br/>number of spots for phenols, terpenoids and alkaloids in the dry season compared to <br/>wet season indicate the influence of moisture stress on accumulation of secondary <br/>metabolites and the need for scheduling harvesting time coinciding with this season. <br/><br/>
