Summary
For Participatory breeding program FGD and online survey was conducted with atakeholders to identify key plant traits and a total 32 diverse set of tomato germplasm was evaluated under organic management using Augmented design to better understand horticultural constraints and identify adapted germplasm for further development. Stakeholders rated more number of fruits per plant, nutrition color (lycopene, β carotene), flavor, virus resistances, stronger root, storability as their top breeding priority, safety was the prior quality characters of tomato. The ANOVA indicated significance difference among genotypes, the result indicated the existence of high morphological variation in tomato genotypes grown in organic system based condition. Yield per plant showed significant variation with the quality parameter like lycopene and β-carotene. To screen out suitable cultivars through multivariate analysis and genetic diversity in tomato genotypes based on 17 characters was estimated using Mahalanobis’s D2statistics. Eight different homozygous divergent genotypes were selected from five different clusters using variance ranking among genotypes within cluster.
