Growth and productivity of different potato varieties under Gaza Strip conditions

摘要: Four potato cultivars were evaluated for their vegetative growth and tuber production. Results revealed that plant length of Spunta and Mondial, number of main stems in Mondial and Alaska and leaf area in Alaska cultivar significantly increased. Yield as tubers weight plant-1 and number of tubers plant-1 in Mondial and larger tubers >60 mm in Mondial and Alaska significantly increased. Tuber properties as tuber weight of Spunta, Alaska and Mondial, tuber length of Spunta and Mondial, tuber diameter of Alaska, Spunta and Mondial, tuber dry weight% and starch% in Lady Rosetta and ash% in Mondial and Spunta showed significant higher increases. It could be recommended to substitute Spunta by Mondial cultivar for home consumption and Lady Rosetta for processing.
