Abstract
Okra (Abelmoschus esculentus) is one of the most important green fruit vegetables in Bangladesh
and is grown in all parts of the country. However, its production varies in the different agroecological regions. Thus, the
present study was conducted in the Sadar Sylhet region, Bangladesh to assess the exotic okra genotype(s) based on morphological,
reproductive and yield attributes. A total of 10 Japanese okra genotypes (JO-1 to JO-10) were comparatively evaluated with the
BARI Dherosh-1 (control) in a randomized complete block design in triplicates. All the morphological features viz. stem colour,
leaf, vein, petiole, pedicel, epicalyx, sepal and fruits were demonstrated almost similar in all the studied genotypes except
JO-5. Considering reproductive traits, results showed the significant variations amid the studied genotypes and an individual
genotype performed better in some unique traits. The highest number of flowers (17), fruit setting (84.56 %) and fruits per plant
(14.1) was obtained in the genotype JO-7 while JO- 3 possessed maximum ovary length (1.5cm), fruit weight (23.86g) which in
turn produced the heaviest fruit. The highest yield was recorded in the genotype JO-7 yielded the highest fruit yield
(14.08 t ha-1) followed by JO-9 (11.92 t ha-1) and JO-3 (11.22 t ha-1) while the lowest yield was recorded in JO-5 (2.47 t ha-1).
In conclusion, the genotypes JO-7, JO-9 and JO-3 may be promising lines for cultivating exotic okra in the Sylhet region, Bangladesh.
