| Abstract | ||
| Aeroponically produced minituber (G0) was studied for basic potato first generation (G1) production under Egyptian conditions. The study contained three factors i.e., two sizes of seeded minituber (smaller or larger than 15 mm), three varieties (Cara, Lady Rosetta and Hermes) and three plant spacing (10, 15 and 20 cm). Obtained results showed significant differences between the tested factors on vegetative growth characters and G1 tuber yield. Larger minituber size produced higher values of stem number, leaf fresh weight, stem fresh weight, leaf and stem dry weight. Cara and Lady Rosetta varieties gave taller plants with higher leaf number and chlorophyll content than Hermes variety. While, Hermes and Cara varieties produced higher stem number than Lady Rosetta. The 15 cm plant spacing gave the highest leaf and stem fresh weight. The highest dry weight was produced in 20 cm plant spacing. Larger minituber size yielded the highest number and weight of G1 tubers. Lady Rosetta and Cara produced higher total yield in the second season. Lady Rosetta gave the highest yield of more than 45 mm size tubers. The highest total tuber number resulted from planting large minitubers in the narrow plant spacing (10 cm) in both seasons. Also, the same treatment gave the highest value of G1 tuber of seed grade (25-35 mm) as number or weight in both seasons. The study recommends the use of large (>15 mm) size aeroponically produced minitubers of the three tested varieties, with 10 cm in row plant spacing for basic seed potatoes first generation production under Egyptian conditions. | ||
