Abstract:

 Landraces of vegetable Roselle (Hibiscus sabdariffa var. sabdariffa L.) are under subsistence and commercial cultivation intribal, rural and peri-urban vegetable farming systems by the tribal folks, small and marginal farmers of south India. Leafyields of these landraces are low in farmer’s conditions either due to poor production potential of landraces or pooragrotechniques. The production potential and the economic value can be enhanced by identifying the promising landracesand their intensive cultivation in the market and truck gardens. In collaboration with National Bureau of Plant GeneticResources, Regional Station, Rajendranagar, 28 landraces of vegetable Roselle were collected from parts of AndhraPradesh and Odisha states of India during 2010-2011. These landraces were evaluated in a randomized block design withthree replications during summer 2013 at Vegetable Research Station, Rajendranagar to assess the production potential andthe genetic variability for various agro-economic traits. The variation recorded within the landrace germplasm for plantheight, total biomass, leaf yield, stalk yield, leaf-stalk ratio and harvest index show its potential for use in the geneticimprovement. The landraces RNR-16, RNR-20 and RNR-27 were promising as indicated by the high leaf productionpotential of 14.22, 12.72 and 11.85 g plant-1, respectively. High estimates of heritability coupled with high genetic advanceas percent of mean for plant height, total biomass, leaf yield, stalk yield and leaf-stalk ratio indicating the possibility toimprove these agro-economic traits through selection programs. Selection is effective for plant height, leaf yield, stalkyield, leaf-stalk ratio and total biomass in vegetable Roselle.
