Abstract
The present investigation was undertaken to analyse the fruits of 13 promising okra cultivars and hybrids for their nutritional and biochemical characteristics, as influenced by the stage of harvest maturity. The fresh fruits of 13 okra cultivars were obtained from the senior Vegetable Breeder, M.P.K.V., Rahuri, and were analysed by following standard procedures. Significant variation was observed with respect to the contents of moisture, crude fibre, crude protein, ash (mineral matter), calcium, iron, total sugars, and vitamin C at different stages of harvest-maturity. Whereas the contents of moisture, crude protein, ash (mineral matter), Ca, Fe, P, and vitamin C decreased with an advancement in the stage of harvest-maturity from 4th to 12th day after the fruit set, the content of crude fibre increased significantly. There was no marked difference in the contents of reducing, non reducing and total sugars, as the pods matured. The data pertaining to chemical nutrients at different stage of harvesting, viz. 4th, 6th, 8th, 10th and 12th days, indicated that okra fruits had the optimum nutrient contents when they were harvested between 6th and 8th day after the fruit set. At the 6th day stage, the moisture content ranged from 87.10 to 90.49% and was highest in cv. Punjab Padmini (90.49%); similarly the crude fibre content ranged from 5.91 to 9.63%, and was highest in cv. Arka Anamika (9.63%); the crude protein content varied from 14.43 to 18.71% and was maximum in cv. RHROH-4 (18.71%); the ash (mineral matter), content ranged from 9.12 to 11.41 % and was highest in cv. RHROH-4 (11.41%); the calcium content varied from (215 to 262 mg/100 g) and was maximum in cv. RHROH-4 (262 mg /100 g); iron varied from 8.17 to 10.54 mg/100 g, with maximum iron in cv. RHROH-4 (10.54 mg/100 g); the phosphorus ranged from 278 to 401 mg/100 g, and was highest in hybrid RHROH-5 (401 mg/lOOg); the total sugar ranged from 7.36 to 10.10% and was highest in RHROH-4 (10.10%); and the vitamin C content ranged from 10.49 to 17.22 mg/lOOg, and was highest in cv. RHROH - 1 (17.22 mg/lOOg). Significant variation in the chemical constitutents of 13 okra cultivars indicated that high nutritional quality cultivars of okra can be developed through breeding and selection.
