Abstract: Nerium (Nerium oleander L.) is an evergreen shrub or small tree in the dogbane family Apocynaceae. The family has a widespread distribution throughout tropical and temperate regions. Nerium is an ornamental plant used in the urban landscaping due to its spectacular flowering which can have different colorations as the variety and its resistance to long drought periods. The objectives of this study were to evaluate four nerium cultivars for vegetative, flowering and yield straits. The cultivars under study showed significant variation for different characters. Among the four cultivars of nerium, Pink cultivar recorded maximum plant height, plant spread, number of branches, internodal length and leaf width and lowest plant height, plant spread, number of branches, internodal length and leaf width, was recorded in Yellow cultivar at six month after planting. Regarding leaf length, highest leaf length was recorded in White cultivar and lowest leaf length was recorded in Yellow cultivar at six month after planting. Similarly Pink cultivar recorded maximum number of inflorescences per plant, number of flowers per inflorescence, flower diameter, corolla tube length, hundred bud weight and yield per plant on other hand lowest number of inflorescence per plant in Yellow cultivar, number of flowers per plant, flower diameter and corolla tube length in white cultivar, hundred bud weight and yield per plant in Yellow cultivar. From the study it was found that Pink cultivar was found as superior for vegetative, flowering and yield traits. Hence, the Pink cultivar may be used in breeding programme for further varietal development.
