In the study, twenty-five accessions of okra collected from different parts of Ghana were evaluated for their horticultural and agronomic attributes in the major and minor cropping seasons of 2008 at the crop and soil sciences experimental field, Kwame Nkrumah University of Science and Technology (KNUST) Kumasi, Ghana, using a randomized complete block design (RCBD) with four replications. The objectives of the experiment were to investigate the horticultural characteristics and performance of all the okra entries. Data collected included fruit and leaf characteristics; Days to first flowering, first flowering node, first fruit-producing node, fresh fruit weight, fruit length at maturity, fruit width, maximum plant height, number of internode, number of seeds per fruit, number of total fruits per plant, seed yield, 100 seed weight. The accessions KNUST/SL1/07Nkrumahene, DA/08/02Dikaba and GH 5787Asontem, GH6102Fetri and ‘Asontem’ showed number of days from sowing to first-flowering at between 44.00 and 48.00 days, first flowering and fruiting nodes at between 5.00 and 6.00th nodes, days to 50% emergence at 8 days after sowing, the average number to total fruits per plant at 60.00 to 145.00 fruits and green immature fruit colour. The results showed that most of the okra displayed symptoms of okra mosaic virus (OMV) and okra leaf curl virus (OLCV). Fruit size varied among the entries. A correlation of the characters with the total fruit production showed that plant height, days to flowering and nodulation, fruit yield and seed yield recorded positive and significant associations, which generally mean that they influenced fruit production or yield. Specific accessions; KNUST/SL1/07Nkrumahene, DA/08/02Dikaba and GH 5787Asontem, GH6102Fetri and ‘Asontem’, identified in this study, could be passed on to breeders for utilization in the okra improvement programmes in Ghana.
