Flowering plants Calendula officinalis with phyllody and virescence and Dendranthema grandiflora with little leaf and formation of bladder like silique symptoms observed in Uttar Pradesh, India. The presence of phytoplasmas in diseased plants was detected by direct and nested polymerase chain reaction assays using phytoplasma-specific primer pairs P1/P7 and R16F2n/R2. In both flowering plants presence of phytoplasma was confirmed by amplification of 1200 bp product of phytoplasma 16S rRNA region with nested primer R16F2n/R2. This is the first report of phytoplasma associated with Calendula officinalis from India.Keywords

Diversity analysis among the seventy six germplasm of lentil (Lens culinaris Medik.) was estimated using morphological markers. Morphological characterization was done based on different parameters like plant height, primary and secondary branches per plant, number of leaves per plant and fresh weights carried out at different stages of the crop and showed wide variability. Dry matter partitioning viz., leaf dry weight, pods dry weight, total dry weight, yield and yield components, pod per plant, seed per plant, 100 seeds weight and seed yield per plant, were recorded at the time of harvest. The results of present investigation suggested that genetic relationships in lentil germplasm using morphological data may be useful for plant improvement and an efficient way to conserve genetic resources of lentil.
