| Abstract:
A series of pickling melon /Cucumis melo/ lines suitable for fresh and brine processing with a wide range of fruit shapes and colours have been obtained by crossing Oriental pickling, hermaphroditic, and birdsnest melons. F4-F7 pickling melon breeding lines derived from crosses between Oriental pickling and hermaphroditic melons /H × OP/ or hermaphroditic and birdsnest melons /H × B/ produced markedly more fruits per unit area than did the best pickling cucumbers tested. Application of the plant growth regulator chlorflurenol /100 ppm/ to the H × B line D17-5-135-7-1-B at the beginning of fruit set increased significantly the fruit number per unit area at the higher plant populations and the percentage of small fruits at all populations. Yield concentration in terms of fruits per unit area in a once-over harvest system was highest in the H × OP and most pickling cucumber lines at a plant population of 100 000 per hectare, the highest density tested. In contrast, the H × B lines produced concentrated yields at both the lower /10 000, 20 000 and 40 000/ and higher /80 000 and 100 000/ densities and were outstanding with regard to the number of fruits produced per plant. | |
