Summary

Beans collected from immature pods of cocoa progency C77 × C23, as early as 15 weeks after pollination, successfully produced seedlings as vigorous as those from mature ripe pods. Seedlings produced by beans from 21-week-old pods were the most vigorous, with vigour based on the integral of all measured growth parameters (leaf number, leaf area, seedling height, girth and root weight). There were close correlations between these growth parameters on the one hand and bean maturity and seedling age on the other, the relations with the former being curvilinear and with the latter linear. Seedling age and bean maturity accounted for between 87–99 and 42–96 per cent respectively of the variations in growth parameters. Multiple regression equations are presented for quick estimations of leaf area.
