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

Abstract

PurposeTwenty 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 methodExperiment was conducted following randomized complete block design with three replications.FindingsAnalysis 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 (19.98) and maximum yield of green fruits per plant (279.59 g) and maximum yield (1.33 kg/m2) was obtained in the genotype G4 (F1-hybrid) followed by G7 and G18. The maximum edible fruit length was observed in G7 followed by G19 and G15. The maximum number of seeds perfruit was recorded in G4.The highest 100-seed weight was found in G4 followed by G17. On the contrary, the lowest seeds per fruit, 100-seed weight, and green fruit yield per plant were obtained from G6. The highest incidence of yellow vein mosaic virus (YVMV) was observed in the genotype G6 and the lowest in the genotype G19 followed by G8, G2, G4, G17 andG12. The cluster analysis grouped 20 genotypes into five cluster and maximum number of genotypes included in cluster 5. Strong positive correlation was observed between yield per plant and days to 50% germination, germination percentage, number of seeds per fruits and 100-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.
