Abstract

The Experiment was conducted at Kittur Rani Channamma College of Horticulture, Arabhavi, UHS, Bagalkot during the year 2018-19. In India even though it is rich source of nutraceuticals, still being treated only as a weed and its cultivation as a food crop and the effects of cultural conditions on its nutritional value is known very little. Estimation of the phylogenetic relationship and knowing the genetic diversity between genotypes in germplasm of any species is essential as it provides useful traits for further genetic development and increase selection efficiency. Genetic diversity in plant varieties can be estimated by observing the phenotypes of the plants and measuring the morphological characters which in turn lay foundation for breeding programs. Hence the present study on Genetic plasticity studies in portulaca, accessions collected from different location of Karnataka were undertaken. The experiment was laid out using randomized block design (RBD) with three replications. Ob

Variability, Heritability, Genetic Advance and Portulaca oleracea.

Conclusion

High degree of additive components like high estimates of heritability coupled with high GAM and presence of high GCV and PCV were obtained for the characters like plant height, number of leaves, leaf area, number of branches, number of inflorescence per plant, secondary branches, plant spread E-W, plant spread N-S, stem girth, number of node, number of flowers, 1000 seed weight, fresh weight of plant, dry weight of plant, foliage yield per plant, foliage yield per plot, foliage yield per hectare, Vit-A, Vit-C, protein calcium, magnesium content, iron content, zinc, oxalate, nitrates and chlorophyll. It indicates in portulaca genetic improvement can be achieve through selection by using the existing germplasms for above characters.
