Yield And Quality Evaluation Of Capsicum Genotype Under Mesh Net (Umn) And Open Field At Organically Managed Soil In Bangladesh

The study has been carried out at organically converted field under olericulture division of HRC, BARI Gazipur during November 2017 to March 2018 to find out suitable genotypes in terms of horticultural traits and nutritional quality along with growing methods. The two factor experiment was set in a split design where net protection was under main plot and eight capsicum genotypes including 2 released varieties were grown in the sub plot with three replication. Number of fruits per plant varied significantly and the highest number of fruits were yielded by CA0034-3 (17) followed by CA 0036 (16) and CA 0034 (15) under net condition. The lowest numbers of fruits were produced by genotypes BARI mistimorich 1 (6) at UMN. Single fruit wt also differed significantly among the genotypes and also had influenced by net. BARI mistimorich 1 and 2 produced the weightiest fruits (124 and 112 g) at UMN while the same varieties produced the lightest fruits (81.2 and 51.8 g) UMN is a good technology to produce capsicum. BARI mistimorich 1 and 2 are the two varieties released by BARI for conventional farming. In this study it was concluded that the released variety showed good growth along with other genotypes CA 0031 and CA0036 in terms of lycopene and β carotene content

Organic System Based Evaluation Of Tomato (Solanum Lycopersicum) For Participatory Plant Breeding In Bangladesh

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
