Agricultural characteristic performance of local and exotic okra (Abelmoschus esculentus L. Moench) genotypes in Bangladesh

Purpose: Twenty genotypes of okra including hybrids and open pollinated varieties both from local and exotic sources were evaluated in the field to study their yield performance and disease response. Research method: Experiment was conducted following randomized complete block design with three replications. Findings: Analysis of variance indicates significant variation among the okra cultivars for all the characters’ studied except days to first germination. The highest number of fruits per plant (۱۹.۹۸) and maximum yield of green fruits per plant (۲۷۹.۵۹ g) and maximum yield (۱.۳۳ kg/m۲) was obtained in the genotype G۴ (F۱-hybrid) followed by G۷ and G۱۸. The maximum edible fruit length was observed in G۷ followed by G۱۹ and G۱۵. The maximum number of seeds perfruit was recorded in G۴.The highest ۱۰۰-seed weight was found in G۴ followed by G۱۷. On the contrary, the lowest seeds per fruit, ۱۰۰-seed weight, and green fruit yield per plant were obtained from G۶. The highest incidence of yellow vein mosaic virus (YVMV) was observed in the genotype G۶ and the lowest in the genotype G۱۹ followed by G۸, G۲, G۴, G۱۷ andG۱۲. The cluster analysis grouped ۲۰ genotypes into five cluster and maximum number of genotypes included in cluster ۵. Strong positive correlation was observed between yield per plant and days to ۵۰% germination, germination percentage, number of seeds per fruits and ۱۰۰-seed weight (g). Limitations: No significant limitation to the report. Originality/Value: The results help to identify the suitable okra genotypes and generate breeding materials.
