Currently, stevia (Stevia rebaudiana Bertoni) seeds are available to growers from many sources, but the origin of these populations is often unknown. Since a natural outcrosser, heterozygous and heterogeneous. We were interested characterize germplasm 16 sources for traits including yield, glycosides, plant morphology, then identify trait correlations. The cultigens evaluated obtained garden se...

Stevia rebaudiana (Bertoni) Bertoni is a perennial herbaceous plant that produces natural low glycemic-index sweeteners alternative to sugar cane. The genetic improvement of needs be investigated increase its productivity. Although this has narrow diversity, through polyploidization may succeed. Meanwhile, genotypic characters tetraploid were previously reported. This study then observed the ph...

Background: Stevia rebaudiana Bertoni, an important anti-diabetic medicinal plant, becomes an inevitable alternative to sugar. Due to the propagation difficulties, tissue culture is the best alternative for rapid mass propagation of stevia plants. Objective: The present study was conducted to optimize a protocol for rapid micropropagation of Stevia rebaudiana by shoot tip explants and to inv...
